A bill for an act establishing standards for obstruction lights on wind energy conversion facilities and providing penalties.

HF 2081 requires wind energy facilities (turbines generating over 100 kilowatts) built on or after July 1, 2026, to use aircraft detection lighting systems (ADLS) for obstruction lights, with existing facilities needing to switch by January 1, 2028. The ADLS automatically activates lights when aircraft are detected, turning them off after the aircraft passes, and must be FAA-approved. Facility owners must maintain continuous ADLS operation, with exemptions for locations where ADLS is impractical due to terrain, airports, or military routes. Violations incur civil penalties of $100-$2,500 per day, with fines going to the state general fund. This bill directly affects wind energy facility owners and operators in Iowa.
