Wisconsin: every permit portal for solar, wind, and storage
The quick find: which office handles each approval a utility-scale project touches in Wisconsin, with the agency's own page. Counties and cities add their own land-use approvals; the state table is the part that is the same across the state.

County and city pages for Wisconsin
From the nationwide permit finder; counties and cities issue most land-use approvals, so start with the jurisdiction that covers the parcel.
- Wisconsin — Water permitting programs (State): Wisconsin environmental authority. Start with this agency for the linked water program. Check construction stormwater, wastewater and water-quality approvals separately; this link does not cover every environmental permit.
- Wisconsin — Construction project review (State): Wisconsin energy / siting authority. Confirm technology, project size, location and the current state-versus-local approval pathway with this authority.
- Wisconsin — local government contacts (City & local): State government / local-government association. Locate the relevant government using this directory; some directories list only cities or only counties. Confirm municipal boundaries and any separate fire, drainage, water or other district authority.
