What’s in it
This bill establishes standards for obstruction lights on wind energy conversion facilities. The bill defines “aircraft detection lighting system” (ADLS) as a sensor-based system designed to detect aircraft as they approach an obstruction or group of obstructions. The bill explains that an ADLS turns an obstruction light on when an aircraft is detected or if there is a system failure, and keeps an obstruction light on until the aircraft exits the coverage area. The bill defines “obstruction light” as a high-intensity beacon, typically red or white, installed on tall structures to warn aircraft pilots of the structure’s presence.
Read the full explanation
The bill defines “wind energy conversion facility” as a wind energy conversion system that collects and converts wind into energy to generate electricity, or a wind turbine that is part of a wind energy conversion system, with a nameplate generating capacity greater than 100 kilowatts. The bill requires all obstruction lights on wind energy conversion facilities constructed on or after July 1, 2026, to be controlled by an ADLS. The bill further requires wind energy conversion facilities constructed prior to July 1, 2026, that utilize obstruction lights not controlled by an ADLS to be altered to utilize obstruction lights controlled by an ADLS by January 1, 2028. The bill requires any ADLS required under the bill to be approved by the federal aviation administration. The bill provides that a wind energy conversion system located at a site where an obstruction light controlled by an ADLS is not appropriate due to terrain limitations, proximity to airports, visual flight rules, or military training routes is not required to utilize an ADLS. The bill provides that an owner of a wind energy conversion system with an obstruction light controlled by an ADLS is responsible for ensuring the ADLS remains continuously operational. The bill provides that an owner of a wind energy conversion facility in violation of the bill is subject to a civil penalty by the commission of not less than $100 nor more than $2,500 per violation. The bill provides that each day a violation continues is a separate and distinct offense, but allows the commission to compromise any civil penalty based on certain factors. The bill directs any civil penalties collected to be forwarded by the chief operating officer of the commission to the treasurer of state to be credited to the general fund of the state.
