The bill amends Chapter 5, Title 21 of the Idaho Code by adding a new section, 21-515B, which mandates the installation of light-mitigating technology systems on wind energy conversion systems. Starting July 1, 2025, any new wind energy conversion system must apply to the Federal Aviation Administration (FAA) for approval of such a system before commencing commercial operations. If approved, the installation must occur within 24 months. Additionally, from January 1, 2026, existing systems that began operations without this technology must also apply for installation and comply with the same timeline.

The bill outlines the responsibilities of developers, owners, or operators regarding the installation and maintenance of these systems, stating that all associated costs will fall on them. It also requires them to notify the Idaho Transportation Department's Division of Aeronautics about the progress of the installation, especially if delays occur. The bill defines "light-mitigating technology system" as a system that reduces the impact of obstruction lighting while ensuring aircraft can still identify and avoid collisions with wind energy conversion systems. An emergency clause is included, making the act effective immediately upon passage and approval.
