LANSING, Mich. — The Michigan Court of Appeals released a significant split decision on Thursday, May 7, 2026, regarding the state’s 2023 clean energy law, which shifts the authority to approve large-scale wind and solar projects from local municipalities to state regulators.

While the three-judge panel upheld the core of the Michigan Public Service Commission’s (MPSC) power to override local objections for major renewable energy and battery storage developments, it also delivered small victories to the 79 local governments that filed the legal challenge.

The court clarified that the MPSC had overstepped by narrowing the definition of which local units are considered “affected” by a project, ruling that any community bordering or containing project land must be included and given the opportunity for developer payments and public input.

In addition to expanding the definition of affected local units, the court rejected the state’s previous interpretation of the timeline for local officials to respond to developers. Under the new ruling, the clock for a municipality to declare that it has a “compatible renewable energy ordinance” begins on the date of a formal meeting with the developer, rather than when a developer first offers to meet.

While local government advocates expressed disappointment that the primary permitting shift remains in place, renewable energy organizations praised the decision for affirming the state’s ability to meet climate goals by streamlining land use for green energy projects without the risk of indefinite local moratoriums.
