Case No. U-20629  
COMMENTS OF CONSUMERS ENERGY COMPANY  
ON PROPOSED SERVICE QUALITY AND RELIABILITY STANDARDS  
FOR ELECTRIC DISTRIBUTION SYSTEMS  
I.  
INTRODUCTION  
The Michigan Public Service Commission (“MPSC” or the “Commission”) issued its  
Order and Notice of Hearing (“Order”) on October 26, 2021, in Case No. U-20629, regarding the  
adoption of revised Service Quality and Reliability Standards for Electric Distribution Systems.  
The Order, with the proposed rules attached, scheduled a public hearing for December 9, 2021 to  
allow presentations by interested persons and to set a final deadline for written comments by 5:00  
pm on January 6, 2022. The proposed rules modify the existing Service Quality and Reliability  
Standards for Electric Systems in Mich Admin Code, R. 460.701 – 460.752, which were adopted  
by the Commission in its January 29, 2004 Order in MPSC Case No. U-12270.  
Stemming from the September 11, 2019 Commission Order in MPSC Case No. U-20464,  
which includes the final Michigan Statewide Energy Assessment and associated jurisdictional  
recommendations, the Commission opened the docket in Case No. U-20629 to establish  
workgroups, led by Staff, for the purpose of reviewing the current Service Quality and Reliability  
Standards for Electric Distribution Systems and to recommend potential improvements to the  
standards. Consumers Energy Company (“Consumers Energy” or the “Company”) participated in  
1
multiple stakeholder sessions, hosted by the MPSC Staff (“Staff”), between December 3, 2019 and  
March 12, 2020. The Company also provided feedback in response to three draft rules sets on  
August 28, 2020, October 5, 2020, and November 25, 2020, in addition to other comments filed  
by Consumers Energy in the Case No. U-20629 docket.  
The comments presented below are provided by Consumers Energy in response to the  
proposed rules attached to the Order. The proposed rules will govern the electric services that the  
Company provides to its electric customers; therefore, Consumers Energy has a direct interest in  
this proceeding. In filing these comments in response to the most recent draft of the Service  
Quality and Reliability Standards for Electric Distribution Systems, Consumers Energy reiterates  
its recommendations expressed in its previous comments filed by the Company in this Case No. U-  
20629 docket. Consumers Energy appreciates the opportunity to provide further comments on  
these standards.  
II.  
COMMENTS  
A.  
R. 460.722 Unacceptable levels of performance during service  
interruptions sub rule (e) and (f)  
The Commission should clarify whether the difference between the required data in  
R 460.722(e) and R 460.722(f) is intentional. R 460.722(e) includes “both normal and catastrophic  
conditions,” while R460.722(f) includes “all conditions.”  
B.  
R. 460.722 Unacceptable levels of performance during service  
interruptions sub rule (b)  
As expressed previously, the Company is not aligned with Staff’s proposal to set the  
performance threshold at 48 hours during catastrophic conditions. When the Company  
experiences storms that are significant enough to cause catastrophic conditions, it is usually the  
case that this weather is having a similarly devastating impact on the neighboring utilities that  
would be close enough to provide mutual assistance quickly. It generally takes 48 hours for crews  
2
from out of state, whose service territories had not been impacted by the same events, to begin to  
arrive in Consumers Energy’s territory, meaning that the Company would be without the mutual  
assistance it would require to recover in this time frame. The Company is not guaranteed to secure  
all the resources necessary through mutual assistance, as the releasing utility has the right to hold  
their resources due to a variety of reasons. Often, neighboring utilities are facing the same  
geographic storm system that the Company is facing, thus reducing the ability to secure help. As  
an example, on Saturday, November 14, 2020, the Company requested mutual assistance for 150  
Distribution Line resources to support a windstorm that was expected to impact the state. All  
utilities in the Great Lakes Mutual Assistance network elected to hold all their resources, as they  
were expected to be impacted by the same wind event.  
Moreover, the catastrophic category covers a huge amount of ground; a storm affecting  
10% of the system is far different than a storm affecting 15% or 20% of the system. Even with  
best efforts, the Company cannot recover from this type of “double-catastrophic” type of event  
(such as the events of March 7, 2017, or December 21, 2013, affecting 18.5% and 21.7% of the  
system, respectively) in a 48-hour period, especially during the winter and still less over a holiday  
as assistance tends to be less available.  
For this reason, Consumers Energy proposes a 60-hour threshold to meet its performance  
standards during catastrophic weather, plus four additional hours on national holidays for every  
1% above the 10% threshold for catastrophic conditions. This will allow for additional time to  
secure the necessary resourcing to meet the response needs.  
In order for the Company to meet these more stringent requirements, the use of pre-staging  
resources will be necessary and will be at an additional cost to the service restoration program.  
Pre-staging involves placing Distribution Line resources at locations expected to be impacted by  
3
the storm event prior to the storm hitting. Recovery in rates will be sought to fund deploying  
resources prior to the event. It should be recognized that planning for an event and staging all the  
necessary resources takes days of preparation and planning. Weather can change and forecasts  
can be wrong. This could cause stranded costs in that the storm does not materialize as severely  
as predicted. It is likely that the Company will seek recovery for these additional costs in the  
service restoration program in the future in alignment with the more stringent requirements  
proposed.  
C.  
R 460.744 Customer accommodation for failure to restore  
service after sustained interruption due to gray sky and  
catastrophic conditions, R 460.745 Customer accommodation  
for failure to restore service during normal conditions  
Consumers Energy remains supportive of the increase of an automated customer outage  
accommodation from $25 to $35 in the proposed rules; however, the Company is not supportive  
of the $2 per-hour additional accommodation. In a 24-hour period, the $2 per-hour credit would  
result in a $48 credit on top of the initial $35 credit. This $83 sum far exceeds an average  
residential customer’s electric bill of $3.89 per day. The outage credit is meant to be an  
“accommodation” and not a “penalty” on utilities, reflected in the recent revision to the title of  
R 460.744 and R. 460.745 from “Penalty” to “Customer Accommodation” for failure to restore  
service. The $35 outage credit already provides accommodation for customers experiencing  
outages, so the additional hourly charge can only be viewed as a penalty to utilities as the state  
predicts increasingly stronger and more frequent storms due to climate change.  
The Company is also concerned that the $2 per-hour customer credit is overly complex,  
will be challenging for customers to understand, and may lead to misunderstandings between the  
Company and customers as to what the proper outage credit should be. This will result in  
unnecessary frustration and dissatisfaction for customers and additional administrative burden for  
4
Consumers Energy. Similarly, the requirement to implement an hourly credit mechanism also  
significantly increases the cost and complexity of implementing the automated credit.  
D.  
Automated Outage Credit  
The Company supports the automatic application of the outage credit to eligible customers’  
bills. However, the Company’s current billing system and Outage Management System does not  
support automatic bill credit applications, nor the new proration provision, and it will be costly to  
build this functionality. As the Company has begun formally initiating the project, it has  
completed a more detailed review of the scope to implement the complex changes to the  
Company’s billing system (SAP), Data Lake, and Outage Management System required to meet  
the current draft rules. At present, the Company’s estimated cost for this project is approximately  
$1.6 million, with a target completion of December 2022. The Company will seek recovery for  
these costs associated with implementation of these requirements. If the updated Service Quality  
and Reliability rules are published prior to December 2022, the Company would ask that the MPSC  
recognize in the rules that additional time would be needed for implementation.  
E.  
Additional Comments  
Consumers Energy would like to draw attention to the benchmarking report provided by  
Public Sector Consultants in February 2020, during the active meeting phase of this workgroup  
process. This study concluded that “statewide standards do not lend themselves to utility-specific  
applications or guideline establishment for improving performance,” noting that “the majority of  
[other] state standards require utilities to restore service as soon as possible and subsequently  
report their reliability performance ….”  
Moreover, Michigan is unique from other states with broad requirements that utilities must  
operate the electric grid within defined parameters, in that Michigan’s standards are “among the  
5
most prescriptive in this study” – an observation made before subsequent Staff redlines that  
proposed further restrictions.  
Finally, the Company encourages reconsideration of the proposed Standards in the spirit  
of the workgroup process. There have been significant redline changes during the comment  
period, and there has not been sufficient opportunity to clarify the rationale behind these changes  
or to allow for in-depth discussion of utility counter-proposals. The Company would welcome the  
opportunity to resume meeting virtually in order to participate in these discussions.

ATTORNEY GENERAL  
January 6, 2022  
Ms. Lisa Felice  
Executive Secretary  
Michigan Public Service Commission  
7109 West Saginaw Highway  
Lansing, MI 48917  
Dear Ms. Felice:  
Re:  
MPSC Case No. U-20629, U-20630 and U-21150  
In the matter, on the Commission’s own motion, to establish a workgroup to review the  
service quality and reliability standards for electric distribution systems and to recommend  
potential improvements to the standards.  
In the matter, on the Commission’s own motion, to establish a workgroup to review the  
Technical Standards for Electric Service and to recommend potential improvements to the  
standards.  
In the matter, on the Commission’s own motion, to propose revisions to the rules  
governing consumer standards and billing practices of electric and natural gas utilities  
regulated in accordance with 1919 PA 419, as amended; 1939 PA 3, as amended; and 1965 PA  
380.  
In its November 4, 2021, order in Case Nos. U-20629, U-20630, and U-21150, the  
Commission requested comments from interested parties regarding the proposed  
service quality and reliability standards, and also proposed revisions to rules  
governing consumer standards and billing practices of electric and natural gas  
utilities. The proposed service quality and reliability standards include customer  
bills credits when electric utilities fail to meet specified levels of performance and  
the provision for an incentive mechanism to encourage electric utilities to improve  
the level of performance of the electric distribution system.  
The Attorney General (AG) is pleased to provide comments that will assist the  
Commission in finalizing the aforementioned standards and rules. The overriding  
objective of the Attorney General is that the reliability and service quality of the  
electric distribution system of Michigan utilities must improve from current levels  
and there should be an urgency to achieve significant performance improvement. In  
that regard, paramount in the Attorney General’s comments below are the  
principles that standards and rules must be fair and reasonable to both customers  
and utilities, and that the failure to achieve the stated standards and service  
quality levels has financial consequences for the utilities or cooperatives under the  
commission’s jurisdiction.  
The Attorney General’s comments below pertain to those sections of the service  
quality and reliability standards filed with the November 4, 2021 Commission order  
in Case No. U-20629. Reference to utility or utilities also includes cooperatives  
under the commission’s jurisdiction.  
PART 1: GENERAL PROVISIONS  
PART 2: UNACCEPTABLE LEVELS OF PERFORMANCE  
The Attorney General does not agree with the proposed revisions to Part 1 and Part  
2 of the Service Quality and Reliability Standards for Electric Distribution Systems.  
As expressed in her August 27, 2020 comments (attached to these comments), the  
creation of the gray sky conditions creates a greater restoration time for customers  
than the prior rules that contain just normal and catastrophic conditions. In fact,  
since these prior comments, it appears that the problem identified by the Attorney  
General has worsened in these new revised rules. In addition, no rule has been  
included to address the protecting customers in the event of a major disaster such  
as the discussed in the National Association of State Utility Consumer Advocates  
2019-01 resolution. A disaster preparedness plan on how the utilities plan to  
respond and work with the cities, townships, police, consumer advocates, and  
community groups in their territories is also needed in these rules.  
As to the outage credits, the Attorney General believes the amount is still not  
sufficient to address the cost incurred by customers following an electric outage. As  
expressed in her prior comments in this docket and others, the outage credits need  
to be automatic and the amount the credit doesn’t properly take into account all the  
costs incurred by customers. The Attorney General provided a snapshot of costs  
incurred by customers as a result of the summer outages and believes that the  
Commission should conduct further investigation into the proper amount of the  
credit. The development of a disaster relief fund, as suggested by the Attorney  
General, would also help alleviate some of the burdens experienced by customers  
following a lengthy electric outage. The Commission can make an addition to Part I  
and create R 460.704. In R 460.704 the Commission could create the authority to  
create disaster preparedness plans and require utilities to file within 6 months of  
these rules being adopted to address such plans before the Commission.  
Moreover, the standards define the unacceptable level if service is not restored or  
the response to a wire down is not achieved in a set number of hours for at least  
90% of the affected customers or incidents. As written, the standards do not provide  
for a maximum acceptable service restoration time or response time for the  
remaining 10% of the power outages and wire-down situations. The remaining 10%  
is often the source of most customers complains when it takes several days or weeks  
for customers to have electric service restored. The Commission should remove the  
gray sky condition as discussed above and create maximum acceptable service  
restorations times or response times. If the Commission adopts the proposed rules,  
then the Attorney General recommends that the Commission establish the following  
maximum service levels:  
R460.722(a) All weather conditions AG Recommendation: Maximum  
restoration time within 4 days (96 hours) for 100% of all customers experiencing  
sustained interruptions. No more than 50 exceptions above 96 hours will be  
acceptable within a calendar year for unusual and difficult service restoration  
situations.  
R460.722(b) Catastrophic conditions AG Recommendation: Maximum  
restoration time within 7 days (168 hours) for 100% of all customers experiencing  
sustained interruptions. No more than 100 exceptions above 168 hours will be  
acceptable within a calendar year for unusual and difficult service restoration  
situations.  
R460.722(c) Gray Sky conditions AG Recommendation: Maximum restoration  
time within 5 days (120 hours) for 100% of all customers experiencing sustained  
interruptions. No more than 50 exceptions above 120 hours will be acceptable  
within a calendar year for unusual and difficult service restoration situations.  
R460.722(d) Normal conditions AG Recommendation: Maximum restoration  
time within 3 days (72 hours) for 100% of all customers experiencing sustained  
interruptions. No more than 10 exceptions above 72 hours will be acceptable within  
a calendar year for unusual and difficult service restoration situations.  
R460.723(1) Wire Down all conditions AG Recommendation: Maximum  
response time within 240 minutes (4 hours) for 100% of all first responder wire-  
down notifications.  
R460.723(2) Wire Down Non-Metropolitan area AG Recommendation:  
Maximum response time within 360 minutes (6 hours) for 100% of all first  
responder wire-down notifications.  
R460.724(b) New Service Installation AG Recommendation: Maximum  
installation time for new service requests within 30 business days.  
PART 3: RECORDS AND REPORTS  
R460.732 Annual report contents. AG Recommendations:  
Subpart (b) through (g), should also require that the utility identify and explain all  
situations where service restoration and service levels exceeded the maximum  
acceptable level.  
Subpart (i) through (l), should be revised to include the threshold hours for  
reporting customer credits recommended by the Attorney General in section  
R460.744 below.  
Subpart (m), the requirement for electric utilities with 1 million or more customers  
to list the 10 worst performing circuits could be very limited given the hundreds of  
circuits operated by the large electric utilities. This requirement should be changed  
to the top 20% worst performing circuits.  
Subpart (n), the requirement for electric utilities and cooperatives with less than 1  
million customers to list the worst performing 1% of circuits could be very limited  
given the number of circuits operated by the large electric utilities. This  
requirement should be changed to the top 10% worst performing circuits.  
Subpart (q), the requirement to report the number of CELID cases for indices  
CELID8hours, CELID24hours, and CELID48hours excludes reporting of other  
cases between CELID8hours and 48hours and any cases longer than 48 hours. The  
requirement should be changed to report cases between CELID8hours and 48 hours  
in 8-hour increments and also cases above 48 hours in total.  
PART 4: FINANCIAL INCENTIVES AND CUSTOMER ACCOMMODATIONS  
R 460.741 Approval of incentive and penalties by the commission.  
AG Recommendation: This section should be revised to add penalties to be assessed  
to utilities if they fail to meet a threshold level of performance or repeatedly fail to  
achieve the minimum performance standards established in R 460.722, R 460.723,  
R 460.724, and R 460.151(2)(a) and (b). It is critical to create an incentive and  
penalty mechanism that is symmetrical. In the approved customer rates, electric  
utilities recover the cost to operate and maintain distribution facilities, including  
repair costs, in order for the utilities to provide the level of service defined in the  
aforementioned standards. Furthermore, electric utilities recover the cost of capital  
investments, including a return on those investments. If some or all of the service  
and the reliability standards are not met repeatedly year after year, customers are  
not receiving the expected value for costs paid and included in rates.  
Therefore, it is necessary for customers to recover the lost value in future years in  
the form of penalties imposed on the utilities by the commission. Similarly, if  
utilizes achieve performance levels that exceed the stated performance levels or tied  
to national average reliability performance standards, they should be rewarded  
with incentive payments. Furthermore, it is necessary to begin a performance  
incentive and penalty mechanism with some urgency given the under-performance  
of Michigan electric utilities relative to other electric utilities in the U.S. [CUB  
Utility Performance Report, 2020 Edition (CUB Report), available at:  
/1602176971/CUB_of_MI_Utility_Performance_Report_2020_Edition.pdf?1602176971 ]  
The Attorney General recommends the following revisions:  
Rule 41.  
(1) The commission may authorize an electric utility or cooperative to receive a  
financial incentive if it exceeds all of the service quality and reliability standards  
adopted by these rules and exceeds national average reliability performance  
standards. The commission may also authorize financial penalties and  
increase credits to customers as provided in these rules if an electric  
utility fails to repeatedly meet one or more of the service quality and  
reliability standards established in R 460.722, R 460.723, R 460.724, and R  
460.151(2)(a) and (b) and national average reliability performance  
standards. [Bolded text proposed by AG]  
(2) A request for approval of an incentive mechanism must include financial  
penalties for failing to repeatedly achieve service quality and reliability  
standards and national average reliability performance standards, must be  
made in either of the following proceedings, and must be conducted as a contested  
case under chapter 4 of the administrative procedures act of 1969, 1969 PA 306,  
MCL 24.271 to 24.288: [Bolded text proposed by AG]  
(a) A rate case proceeding.  
(b) A single-issue proceeding filed specifically to address adoption of an incentive  
program.  
(3) An electric utility or cooperative shall not file an application seeking approval of  
an incentive mechanism, including financial penalties and credit increases to  
customers for failing to meet threshold performance levels and for failing  
to repeatedly achieve service quality and reliability standards and  
national average reliability performance standards, until it has exceeded all  
of the service quality and reliability standards adopted by these rules continuously  
for a period of not less than within 6 months from the effective date of  
implementation of the service quality and reliability standards.  
[Strikethrough and addition of bolded text proposed by AG]  
R 460.742 Criteria for receipt of an incentive or assessment of financial  
penalties: [Bolded text proposed by the AG]  
Rule 42. (1) If an electric utility or cooperative qualifies has received approval for  
implementation of an previously approved incentive and financial penalty  
mechanism, it shall file an application seeking authority to implement the incentive  
mechanism payment and/or penalty amounts at the same time that it submits the  
annual report required by R 460.732. [Strikethrough and addition of bolded text  
proposed by AG]  
(2) An electric utility or cooperative shall not apply for qualify to receive a financial  
incentive approved by the commission unless all of the following criteria were met  
during the previous 12Months calendar year: [Strikethrough and addition of  
bolded text proposed by AG]  
(a) All required reports have been filed in a timely manner.  
(b) All required reports fully comply with the requirements as determined by the  
commission.  
(c) The electric utility's or cooperative’s actual performance for the year shall  
have exceeded achieved an overall performance score of more than 100%  
above the target level for the combined service quality and reliability  
standards as defined within the incentive and penalty mechanism.  
Consumer Billing Standard R 460.151(2)(a) and (b) shall also be included in  
the proposed incentive and penalty mechanism. [Strikethrough and addition  
of bolded text proposed by AG]  
(d) The electric utility or cooperative shall have fully responded to any inquiries  
about the content of the reports made by the commission or its staff in a timely  
manner.  
(3) The commission may impose financial penalties, as defined within the  
financial incentive and penalties mechanism, for an electric utility or  
cooperative failing to achieve an overall service quality and reliability  
standards performance score of 100% for the year or for failing to achieve  
a performance standard for three or more consecutive years. [Bolded text  
proposed by AG]  
The Attorney General also recommends that the commission issue guidelines to the  
electric utilities and cooperatives that will guide their filing for an incentive and  
penalty mechanism. The Attorney General’s proposed guidelines are outlined later  
in this document.  
R 460.744 (Rule 44) Customer accommodations (Bill Credits) for failure to restore  
service after a sustained interruption due to gray sky and catastrophic conditions.  
AG Comment/Recommendation: The proposed restoration time to trigger bill  
credits to customers is set at 96 hours for catastrophic conditions or twice the stated  
time of 48 hours established in the performance standards defined in R 460.722.  
Similarly, for grey sky conditions, the proposed restoration time to trigger bill  
credits to customers is set at 48 hours or twice the stated time of 24 hours  
established in the performance standards defined in R 460.722. This doubling of  
the restoration time to trigger bill credits is unjust and unfair to customers. If the  
standards of performance in R 460.722 are appropriate and reasonable, then it is  
appropriate to use those same standards to trigger bill credits to customers when  
those performance levels are not met. Therefore, the Attorney General recommends  
that the performance levels to trigger bill credits to customers be set at the same  
levels as those established in R 460.722 and to eliminate the gray sky condition.  
R 460.745 (Rule 45) Customer accommodations (Bill Credits) for failure to restore  
service after a sustained interruption during normal conditions.  
AG Comment/Recommendation: The proposed restoration time to trigger bill  
credits to customers is set at 16 hours or twice the stated time of 8 hours in the  
performance standards defined in R 460.722. This doubling of the restoration time  
is unjust and unfair to customers. If the standards of performance in R 460.722 are  
appropriate and reasonable, then it is appropriate to use those same standards to  
trigger bill credits to customers when those performance levels are not met.  
Therefore, the Attorney General recommends that the performance levels to trigger  
bill credits to customers be set at the same levels as those established in R 460.722.  
R 460.746 Customer accommodations (Bill Credits) for repetitive interruptions.  
AG Comment/Recommendation: The proposed number of repetitive interruptions to  
trigger bill credits to customers is set at 6 instead of the stated number of 4  
interruptions in the performance standards defined in R 460.722. The higher  
number of repetitive power interruptions is unjust and unfair to customers. If the  
standard of performance in R 460.722 is appropriate and reasonable, then it is  
appropriate to use the same number of power interruptions to trigger bill credits to  
customers when that performance level is not met. Therefore, the Attorney General  
recommends that the performance level to trigger bill credits to customers be set at  
the same level established in R 460.722.  
The Attorney General also recommends that the commission make it clear that any  
bill credits paid by the utilities will not be recoverable in future rate cases.  
PART 5: WAIVER AND EXCEPTIONS  
R 460.751 Waivers and exceptions by electric utilities.  
(3) An electric utility or cooperative need not meet the standards or grant the  
credits required by parts 2 and 4 of these rules under any of the following  
circumstances:  
(a) The problem was caused by the customer.  
(b) There was a work stoppage or other work action by the electric utility's or  
cooperative’s employees, beyond the control of the electric utility or cooperative,  
that caused a significant reduction in employee hours worked.  
(c) The problem was caused by an "act of God." The term "act of God" means an  
event due to extraordinary natural causes so exceptionally unanticipated and  
widespread within the utility service area, and devoid of human agency that  
reasonable care would not avoid the consequences and includes any of the following:  
[Bolded text proposed by AG]  
(i) Flood.  
(ii) Tornado.  
(iii) Earthquake.  
(iv) Fire caused by other than the utility or cooperative, its employees or  
agents. [Bolded text proposed by AG]  
(d) The problem was due to a major system failure attributable to, but not limited  
to,  
any of the following:  
(i) An accident caused by other than the utility or cooperative, its employees  
or agents. [Bolded text proposed by AG]  
(ii) A man-made disaster caused by other than the utility or cooperative, its  
employees or agents. [Bolded text proposed by AG]  
(iii) A terrorist attack.  
(iv) An act of war.  
(v) A pandemic preventing the utility, or cooperative, from performing  
service restorations from a power outage. [Bolded text proposed by AG]  
CONSUMER STANDARDS AND BILLING PRACTICES  
The Attorney General’s comment below pertain to those sections of the consumer  
standards and billing practices filed with the November 4, 2021 Commission order  
in Case No. U-21150  
AG Comment/Recommendation: The proposed service quality and reliability  
standards removed subpart (a), (b) and (c) from Rule 460.724 with the intent to  
transfer those standards to the consumer standards and billing practices Rule  
460.151. It appears that R 460.724 (c) was inadvertently not transferred.  
Therefore, the Attorney General recommends that this standard be added to R  
460.151(2)(b) to read as follows: “An electric utility shall have a complaint response  
factor of 90% or more within 3 business days.”  
COMMISSION GUIDELINES FOR DISTRIBUTION SYSTEM INCENTIVE AND  
PENALTY MECHANISM  
AG Comment/Recommendation: To guide the development of an effective incentive  
and penalty mechanism that will improve the performance of the electric  
distribution systems of Michigan utilities, the Attorney General proposes that the  
commission direct electric utilities to file an application as soon as possible to  
implement a mechanism that includes the following metrics and meets the following  
guidelines.  
1. Include the service quality and reliability standards in R 460.722, R 460.723, and R  
460.724.  
2. Include consumer standards and billing practices R 460.151(2)(a) and (b).  
3. Include the utility’s annual goal to improve the SAIDI (Excl. MED).  
4. Include service restoration O&M cost per incident (threeyear rolling average, including  
MED).  
5. Include an annual goal to reduce the number of customers who experienced one or more  
power outages during the year of 1 hour or longer.  
6. Include a metric to reduce the number of power outages from trees, wind & weather.  
7. Include a metric to reduce the number of power outages from equipment failures.  
8. Include a metric for the number of miles of line cleared annually for vegetation for LVD  
and HVD circuits.  
9. Include a metric to measure performance against national average reliability performance  
standards.  
10. Each standard, goal, or metric should have an appropriate weight as a percentage of  
100%.  
11. Annually the utility or cooperative would file the actual results showing how it performed  
against each individual standard, goal or metric, and a scorecard showing how it  
performed on an overall basis.  
12. If the overall scorecard results exceed 100% of target, the utility or cooperative would be  
eligible for an incentive payment for the year.  
13. If the overall scorecard results are below100% of target and/or the utility fails to achieve  
a performance standard level for three or more consecutive years the utility or  
cooperative would be assessed a penalty amount for the year.  
14. The incentive or penalty amount should be based on a percent of the revenue requirement  
included in the Company’s current rates for distribution capital investments and O&M  
expense in the most recent rolling five-year period.  
15. Incentive payments and penalties should have reasonable maximum amounts to minimize  
the impact of an unusual or unexpected outcome. These maximums should be set as a  
percentage of the target amount.  
16. If properly designed no deadband range for incentive or penalty payments should be  
necessary. The deadband creates a cliff problem where as soon as the deadband is  
exceeded a large payout or large penalty would need to be assessed.  
These guidelines include the essential standards, goals and metrics to spur the  
desired improvements to the electric distribution systems of the Michigan electric  
utilities and cooperatives. The number of metrics should not be so few as to  
prevents achievement of the desired outcomes, or so many as to water down the  
essential metrics or make the performance measurement process unwieldy. The  
Attorney General’s proposed guideline strike the appropriate balance.  
The Attorney General reiterates its recommendation to the commission about the  
necessity to define the key outlines of an effective performance incentive and  
penalty mechanism with some specificity in order to have similar mechanisms  
among the utilities. The commission should direct the utilities to present a  
mechanism that follows the above-proposed guidelines within 6 months from the  
implementation effective date of the service quality and reliability standards. The  
performance incentive mechanisms filed by the utilities and cooperatives should be  
refined through a collaborative process with Staff, the utilities, and other interested  
parties before final commission approval.  
In summary, the Attorney General looks forward to assist the Commission and  
other parties participating in this difficult undertaking to reduce power outages and  
improve the reliability of electric service provided by Michigan utilities.

DTEE Comments on proposed rules  
U-20629  
DTE Electric is fully committed to improving our customer experience and understands the  
frustration and inconvenience to our customers caused by losing power. In light of that  
understanding and our commitment to continue improving customer safety, reliability and  
affordability, DTE Electric would like to provide the following comments on the proposed Service  
Quality & Reliability Standards:  
Issue #1: Performance standard for customer duration threshold during  
CAT conditions in Rule 22 (b)  
Many of DTE Electric ’s customers had a difficult 2021 Storm season, which was historic in all  
manners of measurement. As discussed throughout the Commission’s electric reliability and  
storm response technical conferences this fall, the state of Michigan expects increased severity  
of weather events going forward. We are taking a comprehensive approach to improving our  
grid resilience in the face of increasing storms, searching across the industry for best practices,  
and engaging all employees within the Company to have an efficient and safe process to restore  
customer outages due to severe weather. DTE Electric believes the trend in severe weather and  
the resultant impacts on our customers requires us to develop an industry-leading storm  
response process.  
Large storms carry with them a variety of challenges. Protecting the public, ramping up internal  
resources, and bringing in external resources are all part of our standard for responding to DTE  
Electric Catastrophic-level events. While the team often ramps up these activities proactively  
before the storm, they require 2 to 3 days to bring in sufficient resources from out-of-state to  
restore outages with more than 70,000 customers affected (which would be defined as a  
relatively small Gray Sky day based on the proposed rule). Additionally, for large storms that  
impact the broader region, securing foreign crews can be especially challenging, as neighboring  
utilities will often not be able to release their crews.  
The proposed rules define Gray Sky conditions as 1%-10% of customers, and Catastrophic  
conditions as >10% of customers. Restoring 90% of customers within 48 hours for a storm  
impacting >10% of customers, is nearly impossible. In the past several years, DTE Electric has  
experienced storms impacting 300,000, 400,000, even 500,000 or more customers, and  
restoring this high a volume of customers is a multi-day event because of the extraordinary  
number of resources that need to be mobilized. During DTE Electric’s last 3 Catastrophic  
(>200,000 customers out), we were able to achieve a 90% restoration in approximately 6 days  
(144 hours) on average. DTE Electric proposes to maintain the 60-hour threshold for  
Catastrophic conditions, which is still a very difficult goal considering the increasing severity of  
storms. Alternatively, DTE Electric proposes a lower percentage of restoration in the 48-hour  
period such as 75% within 48 hours.

DTEE Comments on proposed rules  
U-20629  
Issue #2: Performance standard for CEMI metric in Rule 22 (e) and Rule  
22 (f)  
DTE Electric fully recognizes the customer impact of repetitive outages and the importance of  
the CEMI metric as a critical measure representing the customer experience. With the  
implementation of the investments identified in the 2021 Distribution Grid Plan, DTE Electric is  
confident our customers will see steady and significant improvements in service reliability in  
coming years. We expect to achieve second quartile SAIDI and SAIFI by 2025 and first quartile  
by 2030. With that said, even under an aggressive investment scenario driving reliability  
improvements, we do not expect to achieve the 6% CEMI 4 target until 2028 and 5% until 2035.  
In the near-term we are accelerating our tree trimming program with the $70 million surge  
investment, hiring more local labor to increase the pace of repairs and upgrades to pole-top  
infrastructure, and working our plan to improve communication with our customers during  
outages.  
DTE Electric is concerned that the tightening of the frequency threshold as proposed does not  
allow sufficient time for the Company to execute the required improvements to the distribution  
grid outlined in the Distribution Grid Plan. DTE Electric has been working with the Commission  
and stakeholders on an alternative proposal, that utilizes a performance-based rate making  
mechanism to drive the CEMI 4 metric to a desired state. We recommend that the Commission  
and stakeholders consider performance-based rate making as the appropriate mechanism to  
drive improvements to the CEMI4 metric.  
Issue #3: The $2/hour incremental payments for customers  
experiencing long duration outage event in Rule 44  
DTE Electric understands the inconvenience our customers endure during power interruptions,  
particularly the loss of power for multiple days caused by severe weather conditions. DTE has in the  
past voluntarily offered customer outage credits beyond utilities standards (e.g., during this  
summer’s August storm and in the March 8, 2017 wind storm) as well as setting up shelters for  
residents without power, delivering ice/water during summer storms and blankets/ hand warmers  
during winter storms. DTE Electric is committed to continuing to provide accommodations during  
these unusual circumstances above and beyond the standards’ requirements in the future while  
working diligently to prevent the underlying causes and restore customers as quickly and safely as  
possible.  
Adding the hourly component to credit payments may introduce negative impacts to customer  
satisfaction due to the additional complexity in the credit calculation and customers’ potential  
lack of full understanding of how the credit is being calculated and applied. DTE Electric has  
received 31 complaints regarding outage credits since August, and the vast majority of these  
are due to customers not understanding the criteria. Further complicating the calculation, as  
presently proposed, will drive customer dissatisfaction. For these reasons, DTE Electric has  
proposed an alternative $35 per day incremental payment in lieu of the $2 per hour payment.  
We would like to recommend it again for the Commission and the stakeholders’ consideration.

DTEE Comments on proposed rules  
U-20629  
Conclusion  
As Public Sector Consultants noted in their February 2020 benchmarking report, which was  
submitted in the comment process, the purpose of the utility standards is to define the baseline  
performance for electric service. The report notes that no other state’s utility standards have  
pursued, restoration duration, CEMI performance and customer outage credits in the same level of  
detail that is being proposed in Michigan. The MI Power Grid Incentives/Disincentives workgroup  
can address reliability concerns beyond the baseline performance which these rules address. With  
this in mind, we urge the Commission to reconsider the areas we have outlined.  
Respectfully Submitted,  
DTE Electric Company

COMMENTS OF THE MICHIGAN ELECTRIC AND GAS ASSOCIATION  
Introduction  
The MEGA companies1 appreciate the MPSC staff’s efforts to provide an open forum to discuss  
and collect feedback on the myriad of issues raised as part of the review of the Grid Security and  
Reliability Standards Workgroups. MEGA has engaged in the discussions to represent the unique  
position of small utilities to ensure the staff and other stakeholders understand how the impacts  
of potential changes can vary from that of larger utilities. These comments come from that  
perspective.  
Service Quality Standards (U-20629)  
The MEGA companies offer the following feedback on the Service Quality Standards:  
1 The MEGA companies are Alpena Power, Citizens Gas Company, Indiana Michigan Power Company, Michigan Gas  
Utilities, Northern States Power-Wisconsin, SEMCO Energy, Upper Michigan Energy Resources Company, Upper  
Peninsula Power Company.  
Definitions (460.702)  
MEGA has several comments or suggestions related to the new or modified definitions on  
section 460.702.  
The definition of utility in 460.702 (i) does not make it clear whether transmission-caused  
interruptions should be included in its tracking and reporting or not.  
Grey Sky Conditions (460.722)  
In the proposed Rule 22(e) and (f), grey sky conditions are excluded from (e) and included in (f).  
Annual Reporting Requirements (460.732)  
The MEGA companies would appreciate the opportunity to see and comment on the staff format  
for annual reporting as part of the development process. In addition, the following suggestions  
apply to the reporting requirements:  
460.732(o) should apply to worst performing segments, not circuits. Using segments will  
directly point to areas of the system with repetitive issues. An exemption of this  
requirement for small utilities would also be appropriate since they have relatively few  
circuits and therefore the data wouldn’t provide the type of insight that might be gained  
for a larger utility.  
460.732(p) same device would be a better measure than circuit, or use CEMI, SAIDI,  
SAIFI, CAIDI as better indicators state of the system overall. Similar to subsection (o)  
above, an exemption for small utilities would be appropriate due to the lack of value in  
the data.  
460.732(s) consider an exemption for small utilities or recognition that some utilities  
don’t have the systems capability to make this information readily obtainable or valuable.  
Annual Report Momentary Outages (460.732(r))  
There are several concerns with both the value of the data collected and reporting of momentary  
outages as required in 460.732(r), particularly as it applies to small utilities, and especially on a  
quarterly basis and MEGA would like this requirement eliminated.  
First, as previously stated on this issue in the stakeholder process and in previous comments, the  
data will not distinguish between “good” momentary outages that are designed into the system to  
avoid widespread outages, and “bad” momentary outages that are truly a system failure and  
cause for concern. Further, some small utilities do not have equipment that would collect this  
data, and for some that have AMI, it is relatively new or in the implementation phase.  
Second, expensive software upgrades will be required even for those that have advanced meters.  
If the requirement is retained, MEGA requests an exemption for small utilities is appropriate or  
having a threshold for companies with “mature” AMI based on the amount of penetration in the  
system or number of years since full deployment.  
Outage Credits (460.744 - 460.746)  
The MEGA companies accept the increase in the amount of the outage credit, but annual  
adjustments are cumbersome for small utilities.  
Some MEGA utilities do not have systems in place to automate the credits which will be costly  
to incorporate and may require significant manual processing. MEGA also has concerns with the  
proposal that credits should be prohibited from recovery. As noted, these credits are intended to  
be some compensation for customers experiencing outages but are not a penalty. Any amount  
associated with these credits would be better spent on continued improvements to the distribution  
system to avoid other issues in the future.  
MEGA suggests the following changes:  
Revisiting the amount on a periodic basis, but five years or more would be more  
meaningful to minimize short-term volatility in the number of billing system changes that  
would be needed.  
Providing a date certain for the new credits to take effect. This provides certainty to both  
customer and the utility, providing the utility some time to update its systems accordingly  
to reflect the new credit. For example, if the commission were to issue an order in the  
Fall by September 30, the new amount should give, at minimum, six months for utilities  
to update their systems.  
Outage Credit Thresholds Repetitive Interruptions (460.746)  
The reduction of the threshold of same circuit repetitive outages in 460.746 should include an  
exemption for rural utilities that keeps the threshold at 7 or identify a threshold of customer  
complaints for small/rural utilities with a required report about how the issue will be addressed.  
No basis has been provided to support the need to change this number or the specific reduction  
proposed.  
Technical Standards for Electric Service Rules (U-20630)  
Annual Line Clearing Report (460.3203(i))  
MEGA appreciates the accommodation for small utilities from having to file a quarterly line  
clearing report. As discuses in prior comments, the line clearing plans included in the small  
utility rate cases have not been a source of controversy or concern. The level of data requested,  
and quarterly reporting would require a significant amount of manual work to report.  
MEGA notes that the customer threshold for defining a small utility has traditionally included all  
the MEGA members, and MEGA requests that the customer count threshold be increased to  
recognize that longstanding principle.  
Solid State Meter Reporting: (460.3203(j))  
Some small utilities have not yet adopted and/or are early in the process of adopting solid state  
meters. As such, the requested data is either not available or data systems not currently structured  
to collect or report the data as stated in the rule.  
MEGA requests either an exemption for small utilities, limiting the data required to subsection  
(ii) that describes how the small utility uses the data, or threshold of time after adoption of solid-  
state meters would be an appropriate accommodation for small utilities.  
Extension of Electric Service: (460.3411(16))  
MEGA maintains the addition of this new requirement is unnecessary. Utilities should remain  
responsive to customer requests for meetings and adding language to this Rule implies that there  
remain unresolved issues with Rule 411. There have been court decisions and law changes in  
recent years that have provided clarification of some gray areas, but at this time, the rule and  
framework surrounding it are understood and working well. MEGA does not believe any  
revisions are necessary.  
Conclusion  
MEGA reiterates its thanks to the Commission and the staff for their engagement on these topics  
and consideration of these comments.

BEFORE THE MICHIGAN PUBLIC SERVICE COMMISSION  
Case U-20629  
In the matter, on the Commission's own motion, to establish a workgroup to review the Service  
Quality and Reliability Standards for Electric Distribution Systems and to recommend potential  
improvements to the standards.  
COMMENTS OF THE CITIZENS UTILITY BOARD OF MICHIGAN  
The Citizens Utility Board of Michigan is submitting these comments in response to the order  
U-20629-0055 issued on Nov. 4, 2021 that requested “written comments, suggestions, data,  
views, questions, argument, and modifications concerning the issues” surrounding the proposed  
amendments to the service quality and reliability standards. We appreciate the opportunity to  
make recommendations to the Commission on this important topic. We offer extensive  
comments below.  
I. The Commission should not squander this opportunity to have a  
meaningful impact on electric utility reliability.  
It is well-established that Michigan electric utilities have for many years provided customers with  
relatively poor reliability, with outage frequency as measured by System Average Interruption  
Frequency Index (SAIFI) somewhat above national median, outage duration as measured by  
Customer Average Interruption Duration Index (CAIDI) amongst the worst in the country, and  
total annual outage experience as measured by System Average Interruption Duration Index  
(SAIDI) essentially always in the fourth quartile and often much worse than the 25th percentile.  
This poor performance characterizes the performance of Michigan utilities when either including  
or excluding major event days (MEDs). Graphs and tables illustrating this performance were  
1
included in a recent report by the Citizens Utility Board of Michigan, available from 2021 Utility  
Performance Report_CUB of MI.pdf. The relevant graphs and tables are attached to these  
comments as Appendix A. A comprehensive perspective on recent average performance of  
Michigan’s electric utilities is provided in the following graphs.  
2
As can be seen in the tables in Appendix A, this level of performance by Michigan utilities has  
been persistent since 2013 when national recordkeeping on these topics was initiated by the US  
Department of Energy’s Energy Information Administration. We also know from prior information  
accumulated by a committee of the Institute of Electrical and Electronics Engineers (IEEE),  
which is no longer readily available for reference, that this level of comparative performance by  
DTE and Consumers Energy extends well back into the 20th century.  
This Commission has repeatedly investigated, solicited Staff reports, solicited utility plans, and  
instructed utilities to do better in providing reliable electrical service to their customers. A partial  
history of these efforts includes:  
1991 Investigation in U-9916  
1995 Investigation in U-10908

2020 MiPowerGrid Review of Technical and Quality Standards  
Throughout this history, the reliability performance of Michigan’s major utilities has not materially  
improved. However, it is worth noting that after a major ice storm caused widespread and  
long-duration outages for customers of the Lansing Board of Water and Light, recommendations  
from a citizens review committee and replacement of the General Manager led to rigorous tree  
trimming on a 5-year cycle beginning in 2015, with the results shown in the following graph:  
This case demonstrates that, with appropriate effort, a utility can make a material improvement  
in reliability.  
The MPSC Staff’s proposal for revisions to the service quality and reliability standards  
accomplishes the bare minimum of fixing the obviously irrational problems with the existing  
standards, such as the lack of automatic credits. But the proposal does not go much above that  
4
floor and misses many opportunities to substantially improve consumer protections and  
enhance reliability.  
CUB’s view is that this round of amendments to the Commission’s Service Quality and  
Reliability Standards is likely the last opportunity for potentially many years for the Commission  
to establish a just and reasonable framework for improving the poor reliability of electric utility  
service in Michigan. The standards have not been updated since 2004. Once this review  
process has finished, it will be very unlikely the standards will be changed again for quite some  
time. That means that for years, as severe weather events continue to increase and put  
additional pressure on the grid, utility customers will be locked into what the Commission  
decides here.  
The Staff proposes some commonsense changes, such as requiring the utilities to offer credits  
to customers in an automatic and transparent process and updating the base credit from $25 to  
$35 to account for inflation, plus a very modest and limited variable credit (which we will address  
in more detail in these comments.) But these proposals have all been on the table for about a  
year (since the final Staff report was released). Since then, reliability has become a much bigger  
concern for Michigan residents due to the widespread power outages in the summer of 2021.  
If the Commission simply approves the recommendations in the Staff report, it will appear as if  
the events of the summer had little to no impact on the Commission’s views about the urgency  
of reliability. It seems hard to believe that the impact on customers from the power outages this  
summer would not push the Commission to be more ambitious.  
CUB argues that, instead, the Commission should seize this rare moment where the impetus is  
behind revising these rules for the first time in about 20 years and use that momentum to put  
Michigan on a path for improved reliability. We urge the Commission not to squander this  
opportunity, but rather to further revise these proposed amendments to its Service Quality and  
Reliability Standards before proceeding with the adoption of these rule amendments.  
There are three main areas where the Commission should harness the momentum: First, the  
Commission should adopt a credit that is based on the costs of service interruptions as informed  
by research on the economic cost of outages, and is not just an arbitrary amount. Second, the  
proposed use of a “gray sky” category to determine bill credit eligibility takes the standards  
backwards and needs to be amended. The standards should be expanding the number of  
residents eligible for credits, not reducing the number. Finally, the Commission should ensure  
the standards reflect Michigan’s current level of poor reliability and thus are designed to  
incentivize utilities to work harder to reduce outages, and not reward utilities for unfocused or  
insufficient progress in improving reliability.  
Following the primary text of the comments we show CUB’s proposed redlines to the rules.

II. The Commission should require utilities to collect data to support future  
redetermination of customer interruption costs.  
We argue below that customers should receive bill credits for service interruptions that are  
commensurate with the costs to customers of service interruptions. First, however, we assert  
that it is important for the Commission to have accurate knowledge of customer interruption  
costs even if that information is not used to establish bill credits, that current estimates are not  
adequate, and that the Commission should therefore provide in these rules for the necessary  
accumulation by utilities of data needed to improve estimates of the cost to customers of service  
interruptions.  
As the Commission is well aware, Michigan utilities are planning substantial distribution system  
spending, significantly justified by the need to improve service reliability.1 The Commission has  
already recognized the importance of benefit-cost analysis in relation to distribution system  
planning, soliciting stakeholder discussion and Staff reports on this topic. Most recently, Staff  
reconvened stakeholders for a November 3, 2021 technical conference on benefit-cost analysis,  
on which the Staff reported on December 22, 2021. A portion of that technical conference was a  
presentation on the Interruption Cost Estimate (ICE) Calculator, which has been used by  
Michigan utilities to estimate benefits of improved reliability, by Joseph Eto of the Lawrence  
Berkeley National Laboratory, who has long been a leading researcher on this topic. The Staff  
summary of his presentation is in part that:  
There are some challenges and limitations to the ICE Calculator. The currently used  
surveys are old and outdated. The surveys are from 1980-1990 and represent a time  
when many people did not work at home. Not all utilities or regions of the country are  
represented by the surveys. The surveys are designed around shorter duration  
interruptions and their use is not recommended for interruptions lasting longer than 24  
hours.  
There is a plan to update and upgrade the ICE Calculator at the beginning of next year.  
It would include the development of a consistent set of short duration, customer  
interruption cost survey questions including some to understand customer behavior  
during widespread, longer duration 6 interruptions. It would coordinate the administration  
of surveys to ensure the results are statistically representative of all US regions and  
customer classes. It would also include new information and improvements to design  
and performance. Sponsoring utilities’ responsibilities in the update is to provide funding,  
support survey administration and sampling of customers, and provide feedback on ICE  
Calculator improvements to Berkeley Lab.2  
1 See utility distribution system investment plans in docket U-20147.  
2 See page 5 of the Staff report at  
6
The particular deficiencies of the ICE calculator presented by Eto are especially relevant in  
Michigan where we have a history and continuing problem of widespread, longer duration  
outages. Standard economic reasoning suggests that because customers have fewer options to  
mitigate the effects of an outage when it is widespread and/or of long duration, the costs to a  
single customer of an outage will increase with the scale of the outage and accelerate with the  
duration of an outage. It follows that the estimates produced by the ICE Calculator understate  
the outage costs experienced by Michigan utility customers.  
This deficiency of information to support valid benefit-cost analysis is not only a problem at this  
moment, but one that will endure, as it will likely take a considerable time to improve distribution  
system reliability in Michigan and the problem of distribution reliability will be exacerbated by  
climate change. We therefore recommend that the Commission create a new rule in this rule set  
that gives the Commission clear authority and assigns utilities a clear responsibility to  
accumulate and provide to the Commission and stakeholders the data necessary to accurately  
analyze the economic value to customers of electricity service interruptions. The Commission  
could then make initial use of that authority to require Michigan utilities to participate in the  
Berkeley Lab’s plan to improve the ICE Calculator. We propose the following rule:  
“R 460.xxx Determination of the customer cost of service interruptions  
(1) The commission may adopt on its own motion standard service interruption survey  
instruments and procedures for the purpose of obtaining data about the customer cost of  
electric service interruptions.  
(2) Following each service interruption event experienced by customers of an electric utility  
or cooperative, the electric utility or cooperative shall survey affected customers as  
prescribed by the Commission’s standard service interruption survey instruments and  
procedures. Not later than March 1 of each calendar year, each electric utility or  
cooperative shall convey to the commission in a form and manner prescribed by the  
commission all data accumulated by the electric utility or cooperative through such  
surveys, excluding data that identifies the respondent customers. Such data will be  
made available to researchers and stakeholders by the commission.  
(3) Within one year of the effective date of the amendments to these rules and not less than  
once every three years thereafter, the commission will open a docket for the purpose of  
establishing appropriate formulas and values to determine the customer costs of  
electricity service interruptions that are to be used by electric utilities in reporting service  
interruptions and in analyses of utility investments in distribution system reliability.”  
III. Initial valuation of customer interruption costs  
Economists have estimated the cost of outages through a combination of methods, such as  
surveys of customer behavior and computer modeling of changes in general equilibrium from  
7
power outages.3 Lawrence Berkeley National Laboratory and Nexant have entered dozens of  
datasets of various surveys estimating interruption costs into a meta-analysis that was used to  
develop the econometric model behind the ICE Calculator.  
We entered Michigan-specific data into the ICE Calculator4 and it produced a total cost to  
residential customers of $78.55 million for that CAIDI/SAIFI combined score, or $17.85 per  
customer. With average restoration time (CAIDI) at nearly six hours, that cost comes out to  
about $3 per hour.  
The ICE Calculator model is partially based on willingness-to-pay surveys, which ask  
participants for the maximum price they would be willing to pay for a product or service. Other  
estimates more specifically produced by willingness-to-pay surveys have estimated residential  
costs of power outages at $4.4 per hour5 and $0.07 per minute, or $4.2 per hour.6  
Willingness-to-pay estimates, however, should be viewed as a lower-bound estimate for cost of  
outages. Since electricity is a basic necessity, the willingness-to-pay for electricity is, relative to  
share of income, comparably higher for low-income customers than it is for moderate or  
high-income customers. Their willingness-to-pay is so relatively high, in fact, that it at times  
outstrips their ability to pay. This reality can be observed by the amount of low-income  
customers who go into arrears on their electric bills, as well as through empirical studies of the  
sacrifices low-income customers make to be able to pay for power. Willingness-to-pay studies  
cannot capture the full value of electricity to customers of lesser means.  
In summation, the above sources have estimated $3 to just over $4 as a reasonable hourly cost  
of outages for residential customers, and those estimates should be used as lower bounds due  
to the aforementioned issues with willingness-to-pay surveys when applied to electricity.  
Aside from the use of outage-duration thresholds, which we discuss below, the Staff proposal to  
use $2 per hour for residential customers appears to be materially less than the marginal  
residential customer cost of outage duration. CUB previously proposed $2 per hour for all hours  
of outage as a more reasonable value than the amounts used in the current rules. The evidence  
suggests that CUB’s proposal of $2 per hour for all outages is very conservative, and likely too  
low. CUB recognizes, however, that when introducing a sharp change from the status quo, it is  
prudent to be conservative at the outset. Therefore, we also recommend that the MPSC order a

Study. Southern California Edison Workpapers.

regularly scheduled review process for the value of the credit, so stakeholders can further refine  
the estimate and make it better conform to customer experience. We recommend that the  
proposed rules be changed to provide an initial bill credit for residential customers based on $2  
per hour, but that the rules authorize and require the Commission to update that value based on  
evidence.  
We also note that Staff did not propose a change in the bill credits for business customers,  
which is essentially capped at a proportion of the customer’s monthly fixed charge. This amount  
is generally radically less than the business customer cost of service interruption shown in the  
available evidence. Due to the variability of business customers both as to size of load and the  
sensitivity of the business to outages, the Commission will likely need to use a different  
approach than a bill credit based on outage duration. We recommend the Commission engage  
business customers in consideration of bill credit design for those customers.  
IV. To be effective, bill credits must be automatically paid to customers  
Current rules provide that bill credits are to be paid only to customers “that notify the utility of the  
interruption.” Unfortunately, it is clear from the available record that bill credits available to  
customers under the current rules are rarely paid to customers, with Consumers Energy  
apparently crediting customers for less than 1% and DTE crediting customers only around 5%  
of the bill credits for which customers were eligible.7 Indeed, it is unclear that bill credits are paid  
by some utilities to customers who “notify the utility of the interruption” unless the customer  
requests the bill credit.  
Given that customers receive bill credits at such low rates, it is simply implausible that bill credits  
serve any policy purpose.  
At the time the current rules were adopted in 2004, it was plausible to argue that a utility would  
not necessarily know of an outage or of the duration of an outage unless notified by the  
customer. With the advent of advanced metering and other grid sensors, a utility should know of  
an outage contemporaneously with its start and should have metered records of the start and  
end times of an outage. It is therefore practical for the utility to automatically credit customers for  
outages on the same schedule as it bills for power usage.  
We strongly support the Commission’s proposed amendments to require an electric utility to  
automatically credit customers for outages when the customer is eligible for credit.

V. The Commission should establish outage bill credits that reasonably  
reflect its best estimates of the customer costs of service interruptions,  
rather than limit credits based on the concept that they are penalties  
As embodied in current rules and the proposed amendments thereto, bill credits serve primarily  
as a form of penalty for “unacceptable service,” standards for which are defined in the existing  
rules and would be modified by the proposed amendments; credits are payable only to  
customers who experience “unacceptable service” as prescribed by the rules and in amounts  
that that have no established relationship to the customer costs of service interruptions. Nothing  
in the Commission’s stakeholder process or in the Commission’s records indicate that the  
standards for “unacceptable service” were proposed in light of evidence about the levels of  
service that can cost-effectively be achieved by a utility. Consequently, both the standards of  
service and the amounts of bill credits are essentially arbitrary.  
The Commission should not view bill credits as penalties for “unacceptable service.” Rather, bill  
credits should be viewed as an instrument by which customers are partially insured against the  
costs of service interruption, partial redress for inequities amongst customers in electric utility  
service reliability and restoration, and as a key tool for performance-based regulation of utility  
distribution system reliability. Through provisions regarding utility revenue recovery for bill credit  
liabilities, the Commission can determine the degree to which bill credits serve as penalties for  
“unacceptable service,” without limiting customer bill credits to instances of “unacceptable  
service.” Much of the usefulness of bill credits depends on unlinking bill credits from exclusive  
treatment as a penalty for the utility. The usefulness of bill credits as insurance, for redressing  
inequities, and as a tool for performance-based regulation is optimized when bill credits closely  
reflect the customer costs of service interruptions.  
There is no doubt that most electric utility customers suffer economic harm because of electric  
service interruptions and that that harm exceeds the customer’s avoided payments for electricity  
that is not delivered to the customer. Electric utilities have both a natural and a legal monopoly  
in the provision of electricity distribution services to customers in Michigan, so customers are  
stuck with the level of distribution reliability provided by their utility. Customers have some  
options to defend against lack of electric distribution reliability through use of on-site power  
supply resources, but these are comparatively expensive, are not physically and economically  
accessible for all customers, and in some cases are discouraged or limited by utilities and  
Michigan regulatory policy. Thus, most customers must suffer the consequences of electricity  
service interruptions and either suffer harms or make expenditures to mitigate those harms by  
replacing lost food, eating out, finding alternative lodging, etc. Lost work time either costs the  
employer in lost productivity or the person in lost income.  
We could, as a society, provide optional insurance for utility customers to recover a portion of  
these costs but this is generally not done for small customers because of the marketing and  
10  
transaction costs that would be involved. Furthermore, an approach wherein each customer  
must either provide their own insurance or mitigate the costs of service interruption necessarily  
burdens those customers who, through no fault of their own, have the worst service reliability  
and they generally do not have control over their service reliability. Thus, separating the  
financing of insurance or mitigation of harm from the financing of utility service just adds insult to  
injury for those who experience poor reliability. We think that reasonable provisions for bill  
credits that offset a significant portion of the harms and/or mitigation costs of electricity service  
interruptions would be welfare-improving.  
Providing bill credits for customer service interruptions does not increase electricity bills. To the  
extent that bill credits are not recoverable by the electric utility, bill credits will constitute a bill  
reduction and a utility incentive to cost-effectively reduce service interruption; we further discuss  
these aspects of bill credits below. To the extent that bill credits for customer service  
interruptions are recoverable by the electric utility by, for example, being included in distribution  
rates per kWh, that revenue is also paid out to customers in the form of bill credits. The net  
effect of rate-recoverable bill credits on customer bills is zero, but those customers who  
experience reliable service pay more and those customers who experience service interruptions  
pay less than they would in the absence of bill credits. Bill credits that are not rate-recoverable  
provide a bill reduction to customers who experience service interruptions.  
If service interruptions are essentially random, then rate-recoverable bill credits serve simply as  
insurance. If service interruptions are not really random but instead reflect geographic variation  
in utility infrastructure and performance, then both non-recoverable and rate-recoverable bill  
credits provide more equitable electric service and bills. The commission has limited formal  
evidence regarding inequities in electric service but substantial reasons to assume that there is  
significant inequity amongst customers. Underground distribution and service lines are well  
known to provide more reliable service than overhead distribution and service lines and portions  
of each utility service territory are overhead and other portions are underground but with  
customers in the same class paying the same ongoing rates for distribution without regard to  
whether they are served by underground or overhead facilities.8 The Commission has long  
required utilities to report “worst circuits,” a concept that has meaning only if reliability is not  
uniform and is therefore in some sense inequitable. Recent utility reports filed in docket U-21122  
provide maps showing significant geographical inequities in distribution system reliability.  
There is also good reason to believe that inequities in electric service reliability are correlated  
with income. Newer suburbs were developed after underground facilities became the norm and  
low-income communities are typically located in the older portions of towns and metropolitan  
areas. Distribution systems are upgraded when required by load growth so that growth areas  
tend to have new and improved distribution facilities that are likely more reliable but low-income  
communities are typically located in areas where load is not growing.  
8 We acknowledge that the costs of initial construction of underground facilities as compared to overhead  
facilities are largely addressed through payments at service installation, but this practice falls far short of  
providing for accurate cost allocation and does not address the differences in reliability experience.  
11  
We therefore conclude that a system of bill credits, whether recoverable in utility revenue or not,  
will provide a valuable blend of insurance against the harms caused by service interruption and  
more equitable utility services and rates. Note that in Section X, below, we articulate a standard  
for recovering bill credits based on performance relative to an external standard. Setting bill  
credits at such a level will beneficially provide customers with appropriate insurance against the  
harms or mitigation costs of outages, reduce inequities in service quality and bills as between  
customers with different reliability experiences and likely improve equitability in relation to  
individual and community income. Used in conjunction with allowance for rate recovery of bill  
credits, bill credits will provide a key tool for implementing performance-based regulation of  
utility distribution system reliability. We strongly urge the Commission to change the proposed  
rules to align bill credits with the customer cost of service interruptions.  
It is obvious that both the insurance and equity-improvement of a system of bill credits are best  
served if bill credits reasonably approximate the customer costs of electricity service  
interruption.  
VI. The Commission should penalize and incentivize utilities through the  
cost recovery of bill credits, not through the bill credits themselves  
We next discuss the degree to which bill credits should be recoverable by the utility and the  
mechanisms by which bill credits provide a key tool for performance-based regulation. In effect,  
the Commission can determine the degree to which bill credits function as a penalty without  
limiting the amount of bill credits or the circumstances in which they are paid.  
The utility’s ability to fully recover the costs of bill credits back through customer rates weakens  
any incentive effects on the utility of the obligation to provide bill credits. The ability to recover a  
portion of the bill credit costs also weakens the incentive effect, although less so the farther the  
portion is from 100%. On the other hand, if recovery of bill credits is based on a performance  
standard that is fixed with respect to the utility’s actual performance, then the full amount of bill  
credits per outage event serves as an incentive to the utility to reduce outage frequency or  
duration. If the utility provides service that is worse than the fixed standard, then bill credits will  
exceed recovery and will be a penalty for the utility. If the utility provides service that is better  
than the fixed standard, then recovery based on the bill credits that would be paid under the  
fixed standard will exceed actual bill credits and the utility will receive excess revenue and a  
positive incentive. If the fixed standard is understood to be either permanent or slowly evolving,  
then the expected net present value of avoided bill credits becomes an explicit benefit to the  
utility for improving reliability. If the amount of the bill credits reasonably approximates the  
customer costs of service interruption, then the net present value of avoided bill credits is a  
good proxy for customer benefits of reliability improvements. A comparison of the costs of the  
12  
avoided bill credits to the costs of reliability improvement can be an effective benefit-cost test for  
those reliability improvements. For these reasons, bill credits are a most effective tool for  
performance-based regulation if they reasonably approximate the customer costs of service  
interruptions and are not recoverable in proportion to bill credits paid out.  
A Commission decision to establish bill credits that reasonably approximate the customer costs  
of service interruptions leaves open the question whether the revenue allowed to offset bill  
credits is structured so that utilities are penalized for their existing poor performance or provided  
an opportunity to earn additional earnings to equity. If for example, the revenue allowance for bill  
credits was set at the current expected level of bill credits (or higher), then the utility would only  
experience a positive incentive in that reduced outages would produce reduced bill credits  
which would increase utility earnings. Setting revenue allowance for bill credits at zero would  
mean that the utility would always experience bill credits as a penalty, though that penalty would  
be reduced by reliability improvements. Selection of any intermediate standard of performance  
as the basis for setting a revenue allowance for bill credits would create an initial penalty for  
currently poor performance but provide the utility the opportunity to reach incentive earnings  
through improved performance. The following graph illustrates that the Commission can  
establish the relative use of penalties and incentives by the way in which rate recovery is  
allowed, while providing bill credits that fully reflect the customer cost of service interruptions.  
We therefore conclude that concern about utility financial results need not be a bar to applying  
bill credits that reasonably approximate customer costs of service interruption. Setting bill credits  
at such a level will beneficially provide customers with appropriate insurance against the harms  
or mitigation costs of outages, reduce inequities in service quality and bills as between  
customers with different reliability experiences and likely improve equitability in relation to  
individual and community income. Used in conjunction with allowance for rate recovery of bill  
credits, bill credits will provide a key tool for implementing performance-based regulation of  
utility distribution system reliability. We strongly urge the Commission to change the proposed  
rules to align bill credits with the customer cost of service interruptions.  
13  
We also draw the Commission’s attention to the way in which use of bill credits for  
performance-based regulation helps to focus utility activity to improve reliability. Simply, a utility  
seeking to avoid bill credits because of the incentive effects of a performance-based regulation  
mechanism such as we propose will naturally focus on measures that are directly tailored to the  
avoidance of bill credits. This will include measures that reduce outage duration and not just  
efforts to avoid outages. The utility will focus on both the geography and distribution system  
components that are likely causes of outage. Bill credits as a tool for performance-based  
regulation would also create nearly as much incentive for operations and maintenance  
expenses as for investments, reducing the capital bias that we observe in current distribution  
system investment plans. In contrast, we believe that the most recent round of distribution  
system investment plans proposes expenditure patterns that are significantly less focused than  
we would expect under a performance-based regulatory mechanism that is based on bill credits.  
VII. Limiting bill credits to customers that experience “unacceptable  
performance” undermines the effectiveness of bill credits for any purpose  
CUB stands by its proposal in previous comments that the credit should initially be a simple per  
hour credit that applies to all sustained interruptions (those that last more than five minutes) in  
all grid conditions.  
The $25 flat credit for unacceptable performance in the existing rules has no rationale behind it,  
as all parties seem to have agreed in the lengthy discussions throughout 2020 in the Service  
Quality and Technical Standards workgroup. The proposal to update the credit to $35 to account  
for inflation, therefore, retains the same flaw as found in the original credit. The lack of rationale  
is perhaps best demonstrated by considering the Customer Average Interruption Duration Index,  
which measures the average time a customer is waiting for power to be restored after an  
interruption. The thresholds that the Staff have chosen for bill credit eligibility compare  
unfavorably to the CAIDI score of 356 minutes for Michigan utilities, or 5.93 hours. With a  
customer not receiving a credit until 16 hours under normal grid conditions, 48 hours under gray  
sky conditions and 96 hours under catastrophic conditions, Michigan customers would never  
qualify for credits under the vast majority of outages, despite the material economic harm that  
can come from outages that last well below 16 hours, much less 48 or 96 hours.  
However, based on the available evidence that a residential customer experiences  
approximately a $3 per hour cost of service interruption and with bill credits as provided in the  
proposed rules, a customer that experiences just under a 16-hour service interruption normal  
grid conditions has a cost of approximately $42 but would receive no bill credit and a customer  
that experiences just over a 16-hour service interruption under normal grid conditions similarly  
experiences a cost of approximately $42 but would receive a $35 bill credit. A customer that  
experiences just under a 48-hour service interruption under gray sky conditions has a cost of  
14  
approximately $144 but would receive no bill credit and a customer that experiences just over a  
48-hour service interruption under gray sky conditions similarly experiences approximately $144  
in costs but would receive a $35 bill credit. A customer that experiences just under a 96-hour  
service interruption under catastrophic conditions has a cost of $288 and would not receive a bill  
credit and a customer that experiences just over a 96-hour service interruption under  
catastrophic conditions has a cost of $288 but would receive a bill credit of only $35.  
While the Staff’s idea of the credit increasing hourly after a certain threshold has been passed  
pushes the credit in the right direction, the use of thresholds based on the proposed definitions  
of “unacceptable performance” clearly fails to provide bill credits that will provide any material  
insurance function for customers, fails to address inequities in outage experiences as between  
customers, and fails to provide a useful tool for performance-based regulation. Furthermore, we  
do not believe that a system of credits based on large outage-duration thresholds can be made  
to provide those potential functions of a system of bill credits. While using a short outage  
duration such an hour as a “deductible” for bill credits would likely fit with an insurance  
perspective for most outages, it would fail to provide either insurance or utility incentives for  
customers who experience repeated temporary outages. We urge the Commission to apply bill  
credits to all sustained service interruptions (excluding momentaries) and to make those bill  
credits generally proportional to or increasing in the duration of the service interruption.  
VIII. The Commission should not use the “gray sky conditions” category as  
proposed to determine bill credit eligibility.  
The “gray sky” conditions proposed by staff can refine data collection about outages by  
capturing a middle category of grid conditions that are neither normal nor catastrophic. While we  
support the concept of the “gray sky” category for data collection, the staff’s proposal as is  
should not be used to determine credit eligibility.  
The staff’s proposal would create a new missing middle group of customers who currently  
qualify for credits but would not under the new rules: customers who lose power for more than  
16 hours but less than 48 hours under gray sky conditions. Under the current standards, that  
situation would be considered normal grid conditions, and those customers would be eligible for  
credits. Given the severity of the reliability problem in Michigan, as seen this summer, this is not  
the time to be making it harder for customers to qualify for credits.  
CUB’s proposal avoids these problems entirely by using the same standard for credit eligibility  
regardless of grid condition. Another option would be to simply revise the threshold for gray sky  
conditions from 48 to 16, the same threshold as the staff’s proposal for normal conditions.  
We recommend the Commission not use the gray sky conditions category for bill credit eligibility.  
A very simple way to implement this recommendation is to set the credit at a fixed dollar rate per  
15  
hour, as we advocate above. Alternatively, it should allow customers whose power is out for 16  
hours or more to be eligible for a bill credit under gray sky conditions.  
IX. The Commission should not base utility performance-based regulation,  
bill credits, nor revenue allowances for bill credits on performance  
standards as lax as those in the proposed rule.  
The existing rules, only slightly modified by the proposed amendments, allow a utility that meets  
all of the performance standards in the rules to seek an incentive plan from the Commission that  
would reward the utility for its performance (Rule 460.741) The existing performance standards  
would allow a utility to seek incentive revenue when up to 10% of the utility’s customers who  
experience sustained service interruptions have service interruptions that exceed what the  
rules otherwise deem to be “unacceptable performance.” The proposed rules would further relax  
the standards by allowing utilities to seek incentive revenue even if up to 10% of customers lose  
power for more than 4 days under “gray sky” conditions. While we think it unlikely that the  
Commission would actually authorize incentive revenue for a utility that had these performance  
levels, this illustrates how inadequately these rules are formulated as performance-based  
regulation.  
Although there is not a straightforward way to model these standards in relation to the widely  
available SAIDI, SAIFI, and CAIDI statistics to compare Michigan utilities to those in other  
states, we believe that a utility satisfying the performance standards in the proposed rules could  
still have reliability performance that is amongst the worst in the United States. We note that the  
record in support of this rulemaking does not even include a calculation whether Michigan  
utilities currently satisfy all of the proposed standards for acceptable performance, despite their  
currently very poor ranking in comparison to utilities in the rest of the United States. Although  
there is no current reporting using the “gray sky” conditions defined and used in the proposed  
rules, our review of the available evidence on outage frequency and duration suggests that  
Michigan utilities would currently qualify for an incentive plan under the proposed rules.  
We provided evidence above that basing bill credits on the proposed outage thresholds means  
that customers may experience very substantial harms without qualifying for a bill credit and that  
the proposed bill credits will often fall far short of the level of harm experienced by customers.  
This poor alignment of bill credits with harm is primarily due to the use of these “unacceptable  
performance” standards as the basis for bill credits. As noted above, this problem is  
exacerbated by the Staff’s proposed addition of a “gray skies” condition to the rule.  
For the same reasons, the proposed “unacceptable performance” standards should not be used  
as the basis for determining the revenue allowed a utility for recovery of bill credits.  
16  
We urge the Commission to unlink bill credits and incentives from the list of “unacceptable  
conditions” in the draft rules. We also urge the Commission to direct Staff to provide an analysis  
of whether meeting the proposed “unacceptable conditions” will materially improve current  
electric utility reliability in Michigan.  
X. If the Commission adopts a performance-based regulation method  
based on an allowance for bill credits in rates, the allowance should be  
based on national average performance.  
Based on our experience of the regulatory process, if the revenue allowed a utility for recovery  
of bill credits is not based on an external reference but is instead “negotiated” with the  
Commission, we think it likely that the Commission will start with an approach that is meaningful  
but that utilities will gradually render it ineffective or one based on positive incentives alone. We  
therefore strongly urge the Commission to apply an external reference in these rules.  
Given the current poor reliability performance of Michigan’s utilities, we do not support an  
approach to performance-based regulation that only provides a positive incentive. Furthermore,  
most strategies proposed by utilities in their recent distribution investment plans and in rate  
cases attempt to improve reliability through additional capital investment that has the effect of  
increasing utility profits. Thus, a positive incentive would simply add to those profits and the  
associated increase in rates. We therefore strongly urge an approach that would initially result in  
a net penalty for the poor performance currently achieved by Michigan utilities.  
Since improving reliability is likely to include investments that increase utility profits, we are  
inclined to achieve some symmetry by treating all bill credits as penalties. However, we  
anticipate that would inevitably lead to other utility accommodations, such as an increase in the  
authorized return on equity. We therefore recommend an approach that is symmetric, uses an  
external point of reference, and allows the standard to evolve as climate, technology practices,  
and technology evolve. We recommend that the Commission authorize revenue allowance for  
bill credits based on national average reliability of investor-owned utilities. This will begin as a  
penalty for the current poor performance of many Michigan utilities but enable them to reach a  
level of performance that provides additional earnings by outperforming their peers.

R 460.702 Definitions.  
Rule 2. As used in these rules:  
(a) "All conditions" means conditions reflected by data derived through the  
amalgamation of data from normal conditions, gray sky conditions and catastrophic  
conditions. "All conditions" does not mean only normal conditions or only gray sky  
conditions or only catastrophic conditions.  
(b) "Answer" means that a utility representative, voice response unit, or automated  
operator system is ready to render assistance or ready to accept information necessary  
to process the call. An acknowledgment that the customer is waiting on the line does  
18  
not constitute an answer.  
(c) "Call" means a measurable effort by a customer to obtain a telephone  
connection whether the connection is completed or not.  
(d) "Call blockage factor" means the percentage of calls that do not get answered.  
The call blockage factor is calculated by multiplying the remainder obtained by

subtracting the number of answers from the number of calls, multiplying by 100, and  
then dividing that value by the total number of calls.  
(e) "Approved by the commission" means that a favorable commission order has  
been obtained.  
(f) "Catastrophic conditions" means either of the following:  
(i) Severe weather conditions that result in sustained interruptions for 10% or

Lisa Felice  
Executive Secretary  
Michigan Public Service Commission  
7109 West Saginaw Hwy, 3rd Floor  
Lansing, MI 48909  
Dear Executive Secretary,  
Please accept these comments for filing in the docket of case U-20629, Service Quality and Reliability  
Standards for Electric Distribution Systems.  
These comments address only the need for clear and specific standards to apply to street lighting  
services, which are absent in the proposed draft. The applicable statute requires that the Commission  
adopt “generally applicable service quality and reliability standards.” (MCL 460.10p(5)).  
Members of MI-MAUI local governments served by DTE Electric and Consumers Energy - have a  
particular interest in municipal street lighting. Primary concerns they share, relevant to this proceeding,  
include poor reliability performance of their streetlights, meager or non-existent bill credits for outages  
and lack of standards and penalties to compel utilities to improve reliability.  
As a mostly unmetered service, the application of the current or proposed standards to streetlighting  
can be difficult and ambiguous. For instance, the rules require either unrealistically quick response  
times (those equivalent to residential or business customers) or none at all to streetlight outages,  
depending on how they are read. In practice, the tariffs and contracts in place within various utility  
territories create an inconsistent and patchwork approach to these customer classes.  
Current Rules Fail to Create Quality and Reliability Incentives for Streetlighting Services  
This patchwork approach (or application of rules premised on the assumption that a customer is  
metered) is not achieving the statutory goal of fostering a robust and reliable system. See MCL  
460.10(c). For instance, in the Consumers Energy territory from 2017-2020, streetlighting reliability  
declined every year, and grew from hundreds to more than a thousand outages that took more than 30  
days to resolve. The combination of increased outages and increased average duration resulted in total  
reported outage-days more than doubling over that period. This slide in reliability was no more  
pronounced in the COVID year of 2020 than in 2018 or 2019. Nor are these reliability difficulties limited  
to a single utility or even single lights in unobtrusive locations. In early 2020, it took 18 days from the  
time of report for DTE to restore service to six streetlights near the intersections of S. University and  
State Street in Ann Arbor (an intersection with very heavy U-M pedestrian and vehicle traffic); and that  
outage occurred in January and February, when the daylight hours are short and student traffic is high.  
City of Ann Arbor staff, despite reporting and tracking numerous outages exceeding 30 days, cannot  
recall ever receiving a streetlighting outage credit.  
In this and other ways, the rules fail to offer street lighting customers protections comparable to those  
offered to all other classes of customers. In this comment, we offer some specific adjustments to the  
rules that would improve protection for streetlighting customers. However, we believe the only way to  
provide streetlighting customers with workable, clear, quality and reliability protections fully  
comparable to those covering other distribution customers and consistent with the spirit of the  
Standards would be to develop comprehensive streetlighting-specific rules, and thus our primary  
recommendation is that the Commission order a collaborative process for that purpose.  
Proposed Approach: Collaborative Process to Draft New Section to the Rules  
In general, we take the view that lighting customers should receive the same kinds of protections as  
other customer classes without necessarily having identical provisions, which is best achieved by  
lighting-specific rules.  
First, when customers do not receive service, they should not pay, starting from the moment service  
goes out. No other customer class is forced to pay for service they do not receive.  
Second, when customers of any kind experience long or repetitive outages, additional penalties  
should apply, consistent with the Standards.  
Third, utilities should be required to consistently monitor their own equipment (either physically or  
through electronic means) to proactively identify faults and outages.  
Allowing utilities to continue operating monitoring and response practices that they know  
leave many outages undetected and unreported for long after they occur is unfair to  
customers. Strong evidence suggests that undetected outages account for vastly more outage-  
days than reported outages, once again forcing customers to pay for service they are not  
receiving. Operational and technological solutions to outage detection are readily available.  
Utilities that fail to adopt them should not be permitted to cite lack of evidence as a reason to  
continue charging customers as if the lights were on all the time.  
The proposed rules do not provide any of these protections for streetlighting customers. Thus, our  
primary recommendation is to follow MI-MAUI’s original request to commence a stakeholder process to  
add specific streetlighting quality and reliability content to the Standards. MI-MAUI does not have  
members in all utility territories, and therefore would want to ensure that smaller utilities and  
customers have a voice in standards that would apply to them.  
We believe this is the best approach because there are reasons not to apply the same reliability  
standards to unmetered services as to other electric distribution services. First, as noted above, most  
streetlights are unmetered, thus different ways to monitor service, quantify outage durations and  
frequencies may be needed. Second, it may be economically or socially impractical or undesirable to  
apply the same service restoration timelines to streetlights as to electricity service for occupied  
buildings. But we do strongly maintain that streetlight customers are entitled to statewide uniform  
service and reliability standards rather than leaving it up to each utility to set individual standards,  
especially as resulting reliability levels do not meet statutory goals for robust and reliable service.  
Smaller Changes to this Rule Set  
We recommend wholesale changes to create streetlighting-specific standards, but the following smaller  
changes could be made in the existing proposed rules as a start to addressing these issues.  
“Service restoration” should be defined for streetlighting to occur when “a fixture again  
provides light” to prevent an argument that (as some tariffs provide today) municipal customers  
should pay the same amount for a light that is working as they do for a light that is out, because  
electricity may be flowing to a luminaire that is not providing illumination.  
Annual reports on reliability should be required to include data for streetlighting specifically.  
Right now, the proposed (and current) rules require reports on sustained interruptions and  
credits by customer class, but utilities do not as a rule include streetlighting classes in those  
reports. We recommend the rules be amended to explicitly require both outage information  
and credits paid to streetlighting customers be included in these reports. We suggest adding “A  
report required under this section to report by customer class shall include all customer classes,  
including non-metered customer classes.”  
Sections R 460.744-745 detail customer bill credits for failure to restore service after sustained  
interruptions. We would recommend that for streetlighting, interruption to “lighting service” be  
defined as interruption to “the provision of light by each fixture for which the customer is  
billed,” for the same reason as described in the service restoration discussion above. Under  
normal weather conditions, for example, failure to restore service within 16 hours entitles the  
customer to a bill credit, meaning streetlighting customers would no longer be charged for  
those nights when the fixture is not providing light.  
We have consistently advocated for better protections for street lighting customers since this docket  
was opened. While street lighting customers comprise a small percentage of electric service customers  
and load, the statute directing the Commission to adopt service quality and reliability protections  
requires that they be of general applicability, meaning that streetlighting customers must receive the  
same basic protections afforded all other customers. We urge the Commission to order development of  
standards that will bring street lighting customers under the same protective umbrella as all other  
customer classes, ideally by stepping away from a one-size-fits-all approach to crafting streetlighting-  
specific service quality and reliability rules.  
Sincerely,  
Rick Bunch  
Executive Director
