A three-judge panel of the Michigan Court of Appeals ruled on Thursday that state regulators followed proper legal procedures when drafting implementation rules for a 2023 law that shifts approval authority for large wind, solar, and battery projects from municipalities to the Michigan Public Service Commission. The panel rejected several arguments brought by local governments but sided with municipal challengers on two narrow interpretations of the statute concerning timeline triggers and community eligibility for project payments.
The ruling carries direct implications for a wave of renewable energy proposals currently moving through the state’s permitting pipeline. It also establishes a clearer boundary between municipal zoning authority and statewide energy policy under Public Act 233, a law passed along party lines in 2023 to accelerate Michigan’s renewable transition after local opposition delayed multiple planned installations.
State regulators framed the decision as a validation of their rulemaking process. “While the Commission continues to review the impact of specific findings of the Court’s decision on cases before us, today’s decision largely affirms the Commission’s approach and allows for continued and timely implementation of the law,” said Matt Helms, a spokesperson for the Public Service Commission.
Attorneys representing the coalition of local governments that filed suit against the state characterized the outcome as partially successful but incomplete. Michael Homier, who represented dozens of municipalities, said he is “pleased with portions of the ruling that favored his clients, but disappointed the court didn’t apply the same reasoning” to the remaining legal challenges. The Michigan Townships Association, which has lobbied extensively against the state’s permitting framework, did not respond to a request for comment.
The court’s two concessions to local governments centered on procedural timelines and geographic definitions. Under the original 2023 law, local jurisdictions have 30 days after a meeting with developers to initiate their approval process. State regulators had written rules that started the 30-day window when developers merely offered to meet. The judges rejected that interpretation, stating the clock must start after the actual meeting occurs, despite state arguments that local officials might delay projects by simply refusing to meet.
The panel also sided with municipalities on the definition of an “affected local unit.” State rules had limited the designation to government bodies holding zoning jurisdiction over project land. The court ruled instead that any county, township, city, or village whose boundaries touch the proposed project site qualifies as affected, which makes those jurisdictions eligible for compensation payments from developers.
Judges Christopher Murray, Michael Gadola, and Michael Kelly otherwise upheld the commission’s authority. They dismissed arguments that the agency violated rulemaking procedures, wrote overly restrictive terms for local ordinances, or improperly curtailed municipal power. The 2023 law permits local governments to maintain approval authority over renewable projects if they adopt a “compatible renewable energy ordinance” with standards no stricter than statewide benchmarks for noise, setbacks, and related measures. Communities that do not adopt such ordinances cede approval jurisdiction to the Public Service Commission.
Renewable industry groups welcomed the ruling as a confirmation of local autonomy alongside state-level development goals. Laura Sherman, president of the Michigan Energy Innovation Business Council, said the decision “affirmed the ability for Michiganders to use their land as they wish while stimulating job creation and economic development.”
