A bill for an act relating to the siting and operation of renewable electric power generating facilities.

SF 2447 establishes statewide setback requirements for renewable energy facilities in Iowa, directly affecting local governments (cities/counties) and developers of wind, solar, and battery storage projects. The bill mandates specific minimum distances: wind facilities must be 3 times their height from homes/community buildings, 1.1 times their height from non-participating property, and 1.1 times their height from roads or utility lines. Local authorities cannot enforce stricter setback rules than these standards, though they may adopt limited additional requirements like a 30-hour annual shadow flicker limit or 47-decibel sound limits. The law applies to all wind facilities proposed after January 1, 2025, and sets uniform rules to streamline approvals for renewable projects.
