The Commercial Solar Facility Decommissioning Act establishes regulations for the decommissioning of solar power facilities in Oklahoma. It defines key terms such as "generation assets," "grantee," and "solar power facility," and outlines the responsibilities of grantees regarding the removal of solar facilities from landowner properties. The Act mandates that solar power facility agreements include provisions ensuring that grantees are responsible for safely removing all associated equipment and restoring the land to its original condition. Additionally, landowners must make timely requests for decommissioning within 180 days of the facility ceasing operations or receiving notice of intent to decommission.

The Act also requires grantees to provide financial assurance to cover the costs of decommissioning, with acceptable forms including bonds and letters of credit. The amount of financial assurance must be based on estimates from an independent engineer and must be updated regularly. Importantly, any agreement provisions that attempt to waive rights or liabilities under this Act are deemed void, and individuals harmed by violations are entitled to seek injunctive relief. The Act is set to take effect on November 1, 2025.
