Michigan’s utility regulator issued a formal straw proposal on August 6 to tighten the financial incentive and penalty framework that links DTE Energy and Consumers Energy earnings directly to how reliably they keep the lights on, opening a new public comment round in a proceeding that could reshape how Michigan customers pay for poor grid performance.
What the MPSC is proposing
The Michigan Public Service Commission is seeking comment on a straw proposal that would refine the focus areas of the MPSC’s performance incentive initiative, centered on ways to improve utility reliability performance, customer outcomes, and safety (Case No. U-21400). The commission released the straw proposal to facilitate discussion on the second phase of its performance incentive initiative, which is exploring challenges to utility readiness to accommodate and leverage growth of distributed generation, electric vehicles, and other cost-effective distributed energy resources.
On February 27, 2025, the commission issued an order adopting a modified version of a proposal developed by MPSC staff and directed Consumers Energy Company and DTE Electric Company to file a proposed performance mechanism in standalone dockets by April 15, 2025. The August 6 straw proposal is the next phase of that effort.
Michigan regulators previously announced financial penalties for DTE Energy and Consumers Energy if they fail to reach reliability metrics, with the commission imposing incentives and disincentives based on whether the companies meet targets such as reducing the length of power outages, establishing penalties for utilities whose customers experience four or more sustained power interruptions per year, or limiting the number of customers experiencing repeated outages.
The proposal represents a significant step toward performance-based regulation, a type of utility oversight that connects utility earnings directly to the achievement of measurable targets.
The reliability backdrop
The commission set a limit for penalties and incentives at a total of $10 million for the 2026 calendar year. Consumer advocates have argued that the current penalty cap is modest relative to utility earnings, describing it as insufficient to meaningfully change utility behavior.
DTE and Consumers together serve roughly 80 percent of Michigan’s electric customers. That concentration means that any financial mechanism the commission adopts will affect a substantial share of the state’s households and businesses.
DTE Energy’s annual net income for 2024 was $1.40 billion. CMS Energy’s annual net income for 2024 was $993 million. Consumer advocates have argued that the current penalty cap is modest relative to those earnings.
Storm costs add pressure on the proceeding
The performance incentive debate is playing out alongside significant new storm-related costs. The commission separately approved an application from Consumers Energy requesting accounting authority to defer significant costs from a series of high-impact storms in mid-March.
Those storms caused more than 6,700 downed wires and other damage, including the need to replace 515 poles and 1,330 crossarms, costing an estimated $57 million in operations and maintenance costs across lower Michigan.
The storms pushed Consumers’ total expense for service restoration from January to April to $111 million, while the utility’s total amount approved for 2026 is $154 million. The commission’s approval is for accounting treatment only, noting that Consumers must still meet all evidentiary burdens of reasonableness and prudence before the utility can recover restoration costs through rates in a future proceeding. That review raises the stakes for how robust the performance incentive structure must be to offset ratepayer risk.
Next steps
Michigan’s approach is part of a wider national wave of performance-based utility regulation. As grid stress grows, commissions across the country are weighing whether traditional rate cases alone are sufficient to hold utilities accountable between filings.
The Michigan model embeds financial consequences into ongoing utility operations rather than waiting for the next rate case. How aggressively the MPSC tightens the August straw proposal’s metrics will determine whether any penalty ceiling rises in future years.
Initial comments are due by 5 p.m. October 1, 2026, and may be filed using the MPSC’s E-Dockets, mailed to the Executive Secretary, or emailed to [email protected]. Reply comments must be filed by 5 p.m. November 5. The commission has not yet announced a target date for a final order.
Advocates including the Citizens Utility Board of Michigan have submitted comments in the proceeding, and have stated that getting the details right is critical if the new rules are actually going to motivate utilities to improve service. They have also argued that utilities should be barred from earning incentive payments while their performance remains below national industry benchmarks, and that any penalties ultimately be paid directly to affected customers as bill credits rather than absorbed by the state.
Michigan is among the worst in the U.S. for frequency and duration of outages, giving that debate an urgency that regulators in quieter states rarely face. For Michigan ratepayers, the outcome of the MPSC’s August proposal will set the financial stakes utilities face every time a storm takes down a line.
