Provides that, beginning June 1, 2025 and subject to Federal Aviation Administration approval to equip and operate light mitigating technology for at least 30% of the proposed wind towers included within a commercial wind energy facility, a county shall require the facility owner of a commercial wind energy facility constructed beginning in 2019 or later to install light mitigating technology at the commercial wind energy facility.
