Dive Brief:
- The Michigan Public Service Commission on Thursday ordered a series of reliability improvements for Consumers Energy and DTE Electric, including bolstering the utilities’ vegetation management programs and prioritizing equipment replacement programs “based on inspections and the actual condition of the equipment instead of solely on age of facilities.”
- Michigan regulators launched the audit in 2022 following a string of storm-related outages and downed-wires incidents that resulted in the death of a 14-year-old child. Restoration times at both utilities are “worse than average,” the audit concluded in September.
- Both utilities say they are reviewing the PSC’s order and taking steps to improve reliability. The two utilities serve more than 80% of Michigan residents.
Dive Insight:
Almost 500,000 Michigan customers lost power, some for several days, following severe storms in August 2022. And in addition to the young girl killed, two boys were critically hurt by contact with power lines downed in the storm.
“After a thorough and detailed audit process, now is the time for implementation,” Commissioner Katherine Peretick said in a statement. “The recommendations provided by the third-party experts will now be embedded into decisions going forward, including distribution plans and rate cases for cost recovery.”
DTE and Consumers serve more than 4 million customers combined. The audit was performed by The Liberty Consulting Group.
The commission directed both utilities to file a report on downed-wires policies and resources by Aug. 29.
“The steps the Commission is outlining today build on what we’ve learned from the audit and a series of initiatives going back nearly a decade and take concrete actions to continue addressing reliability issues that have frustrated customers,” PSC Chair Dan Scripps said.
For both utilities, the PSC ordered they focus on:
- Expansion of resources to address downed wires, and for the utilities to file information regarding personnel, protocols, policies and procedures, around downed wires, and methods to ensure public safety;
- an analysis of how to balance capital spending vs. operations and maintenance spending and tree trimming, to meet reliability goals; and,
- aligning requests for cost recovery in rate cases with previously filed electric distribution plans, “with full explanation of any changes, including evidence and rationale.”
For Consumers, the PSC wants the utility to:
- Analyze the impacts of utilizing a 4-year fixed tree-trimming cycle instead of the company’s current 7-year cycle;
- increase the number of employees and contractors on hand during outages; and,
- evaluate the costs and benefits of burying more low-voltage distribution lines beyond the company’s currently approved undergrounding pilot program.
“We’re reviewing today’s MPSC recommendations based on the audit of our company’s storm response, and we look forward to working with them to deliver on our shared vision of a stronger, more resilient electric grid for Michigan,” Consumers said in a statement.
The utility said it is “fully committed to delivering energy reliably to our customers,” adding that it has been improving service to through a reliability “roadmap,” reducing outage duration and “moving closer to our goal to restore power in all situations in less than 24 hours.”
For DTE, the commission’s recommendations included:
- For the utility to submit more “detailed distribution plans than it has in the past, with realistic analyses of costs and benefits and alternatives”;
- filing a strategy for improving the safety and reliability of its 4.8-kV system, investments in Viper reclosers, and a comparison to alternatives including tree trimming, in its next distribution plan;
- encouraging the company to continue its subtransmission cable replacement program while also providing “realistic and actionable investment and timeline plans for future cable replacement planning when it submits cost recovery requests”; and,
- a “deeper analysis” of planning in making capital and operations and maintenance investments.
DTE said in a statement that the PSC’s order “aligns with our commitment of reducing outages by 30% and cutting outage time in half by 2029.”
With the combination of $1.5 billion of investment in the electric grid last year, coupled with less extreme weather, our customers experienced a nearly 70% improvement in time spent without power in 2024,” the utility said. “We look forward to continuing to work with the MPSC on ways to provide our customers with the safer, more reliable and resilient, cleaner and affordable energy they demand and deserve.”
