Michigan Public Service Commission Faces Criticism Over Renewable Energy Plan Revisions

Strategic Insights

— 1 min read

The Michigan Public Service Commission (MPSC) has been criticized for its Proposal for Decision (PFD) in the case of Consumers Energy Company's renewable energy plan, which has been deemed inadequate by The Ecology Center, Environmental Law & Policy Center, Union of Concerned Scientists, and Vote Solar (collectively referred to as the Clean Energy Organizations or "CEO"). The CEO has submitted exceptions to the PFD, outlining the commission's failure to adopt key recommendations regarding load forecasting, energy storage, and curtailment in the company's next Integrated Resource Plan (IRP).

Key Takeaways:

  • The MPSC's PFD failed to adopt the CEO's recommendation regarding modeling load forecast sensitivities in the IRP.
  • The commission also failed to discuss the CEO's recommendations regarding curtailment and storage resources, despite the company's support for these measures.
  • The CEO has asked the commission to order Consumers to model curtailment of renewables, including off-peak renewables production, on the final proposed course of action, as well as any additional sensitivities representing full decarbonization, in its next IRP.
  • The organization has also requested that the commission order Consumers to develop plans to meet the energy storage requirement, including identifying potential sites for energy storage projects and planning for those projects in its next IRP.
  • The MPSC's decision has been criticized for prioritizing form over substance and delaying the implementation of IRP modeling requirements.
  • The CEO's recommendations were based on a thorough review of the record in the case, and the organization believes that the commission should have adopted these recommendations in its PFD.

Statistics:

  • 3 (number of recommendations made by the CEO regarding load forecasting, curtailment, and energy storage)
  • 12 (page number of the CEO's brief where they argued for swift implementation of IRP modeling requirements)
  • August 11, 2025 (date of the CEO's submission of exceptions to the PFD)
  • Public Act 295 of 2008 (regulation that the MPSC is seeking to amend)
  • 2023 (year in which Public Act 235 was amended)
