Relating to the authority of a taxing unit to enter into an agreement to exempt from ad valorem taxation a portion of the value of property on which a renewable energy facility is located or is planned to be located.

HB 4057 prohibits local taxing units (municipalities, counties, and county commissions) from entering agreements to exempt renewable energy facilities from ad valorem property taxes. The bill specifically applies to solar, wind, and qualifying battery storage facilities that sell energy wholesale to the power grid. It blocks tax exemptions for both the real property where these facilities are located and any related tangible personal property during the agreement term. This law directly affects local governments seeking to offer tax incentives for renewable energy projects meeting these defined criteria.
