Utility landscape

• Consumers Energy IOU

  Lower Peninsula of Michigan, serving approximately 1.8 million electric and 1.7 million gas customers across a large swath of central and western Michigan

  Consumers Energy has pursued aggressive rate increases tied to its Clean Energy Plan, seeking significant capital recovery for grid modernization and renewable build-out. The MPSC has been active in scrutinizing its integrated resource planning and cost allocations, particularly following legislative mandates under Public Act 235 of 2023.

• DTE Electric Company IOU

  Southeastern Michigan, including Detroit metro and surrounding counties, serving approximately 2.3 million electric customers

  DTE Electric has faced regulatory pressure over reliability performance and storm restoration response, with the MPSC imposing enhanced service quality metrics. Recent rate cases have focused on accelerated coal retirement timelines, battery storage procurement, and infrastructure hardening cost recovery.

• DTE Gas Company IOU

  Southeastern and mid-Michigan natural gas distribution, serving approximately 1.3 million customers

  DTE Gas filed for rate increases tied to pipeline integrity programs and leak detection upgrades under federal pipeline safety mandates. The MPSC has pushed back on certain O&M capitalization practices and required enhanced low-income affordability plan integration.

• SEMCO Energy Gas Company IOU

  Southeastern Michigan and Battle Creek area, serving approximately 310,000 natural gas customers

  SEMCO, a subsidiary of the Southern Company Gas portfolio, has maintained a relatively stable rate environment but faces scrutiny on pipeline replacement cost recovery and alignment with Michigan's building electrification policy discussions.

• Midwest Energy Cooperative coop

  Southwestern Lower Peninsula of Michigan, serving rural electric customers across Cass, St. Joseph, Branch, and adjacent counties

  As a distribution cooperative served by Wolverine Power Cooperative's generation mix, Midwest Energy has been navigating wholesale power cost pass-through implications as Wolverine transitions away from coal generation under EPA pressure and Michigan's clean energy standards.

• City of Holland Board of Public Works muni

  Holland, Michigan and portions of Park Township in Ottawa County

  Holland BPW operates a vertically integrated municipal electric utility and has been recognized for its geothermal snowmelt system and renewable energy commitments. It operates largely outside MPSC retail rate jurisdiction but coordinates on transmission access and wholesale market participation through MISO.

Key issues

• Implementation of Public Act 235 and Public Act 233 of 2023: The MPSC is actively developing rules and integrated resource plan review standards to enforce Michigan's mandate of 100% clean energy by 2040 and 50% renewable portfolio standard by 2030, requiring all major IOUs to file updated long-term energy plans with accelerated coal retirement schedules and storage procurement commitments.
• DTE Electric and Consumers Energy reliability performance enforcement: The MPSC has intensified oversight of SAIDI and SAIFI metrics following repeated storm outage criticism, with pending proceedings examining whether performance-based ratemaking mechanisms and penalty structures should be codified into rate case outcomes to create stronger financial accountability.
• Rate affordability and low-income program expansion: With cumulative electric and gas rate increases from multiple consecutive rate cases straining household budgets, the MPSC is examining mandatory low-income assistance program enhancements, shut-off protection rule reforms, and potential cross-subsidization structures as part of broader energy equity proceedings.
• Grid modernization and AMI capital recovery: Both DTE Electric and Consumers Energy are pursuing multi-hundred-million-dollar advanced metering infrastructure and distribution automation investments, with the MPSC scrutinizing cost-benefit methodologies, cybersecurity standards, and the appropriate rate of return and amortization periods for these deferred regulatory assets.
• Natural gas infrastructure long-term role and stranded asset risk: In the context of Michigan's 2040 clean energy mandate, the MPSC is beginning to grapple with the policy framework for gas distribution system long-term planning, including whether utilities should be required to produce gas network transition plans and how to address potential stranded asset exposure for ratepayers if electrification accelerates.

Upcoming
