Relating to restoring local jurisdiction to state political subdivisions over certain electric power facilities.

HB 4509 prohibits counties and municipalities from imposing local zoning, building permits, licensing, or other regulations on certified microgrid districts and certified high impact data centers. It bans local governments from enacting ordinances that restrict the development, operation, or expansion of these specific projects. The bill designates a "Data Economy Liaison" at the Department of Commerce to coordinate with developers and expedite project approvals. This measure removes local regulatory authority over these projects, directly affecting county/municipal governments and the owners of certified microgrid and data center facilities.
