PSC of Wisconsin has siting authority for wind/solar ≥100 MW (Wis. Stat. §196.491). Projects <100 MW: local CUP/SUP under county/town zoning governs. Local restrictions on wind systems must meet one of 3 conditions: (1) public health/safety; (2) not significantly increase cost/decrease efficiency; (3) allows comparable alternative. Local solar restrictions face similar reasonableness standard. No statewide preemption below 100 MW threshold — strong local control. MISO interconnection territory statewide.
