What the law actually does
Senate Bill 271 of 2023 (Public Act 235 of 2023) requires utilities to hit a 50% renewable portfolio by 2030, 60% by 2035, and 100% “clean” electricity by 2040. Companion bills raised efficiency mandates and — in Public Act 233 — let the Michigan Public Service Commission override township zoning for large wind, solar, and battery projects.
- Rural counties host the turbines. The electricity feeds the statewide grid, largely serving downstate load.
- Capacity is built for windy and sunny hours. On still, overcast days the blades sit and gas or storage fills the gap.
- Residential rates rose about 27% from 2019 to 2026. Utilities recover build costs plus a guaranteed return through your bill.
- Local tax revenue (schools, roads) does land in host counties. It does not show up as a lower electric bill.
