Providing that any lease or easement involving commercial wind or solar electric generation resources shall not be in force and effect until the board of county commissioners of the affected county approves the commercial wind or solar electric generation project.

SB 173 requires county commissioners to approve commercial wind or solar energy projects before any related lease or easement agreement becomes binding. It directly affects facility owners (those developing projects with at least one megawatt capacity for sale) and landowners, as these agreements cannot take effect until county approval is secured. The bill mandates that counties with zoning regulations must issue a building or development permit, while counties without such regulations must enter a development agreement. This requirement applies to all new agreements filed on or after July 1, 2025, and does not affect leases recorded before July 1, 2011.
