The bill aims to revise laws related to wind generation facilities in Montana by establishing specific height and lighting requirements for wind turbine towers. It introduces several definitions, including "aircraft detecting lighting system," "turbine rotor hub," "wind generation facility," and "wind turbine tower." Notably, the bill stipulates that starting January 1, 2026, wind turbine towers cannot exceed 350 feet in height, measured from the natural ground level to the middle of the turbine rotor hub. This height restriction does not apply to towers constructed before this date.

Additionally, the bill mandates that from January 1, 2026, wind turbines must adhere to lighting requirements that prevent excessive illumination, aligning with the minimum standards set by the Federal Aviation Administration (FAA). Furthermore, all wind generation facilities with towers exceeding the specified height must install FAA-approved aircraft detection lighting systems. The provisions outlined in the bill are intended to be codified as part of Title 75, chapter 26, and the act will take effect on January 1, 2026.
