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 for the grantee to safely remove all solar energy devices and associated infrastructure, restore the land to its original condition, and ensure that any holes or cavities created during the removal process are filled appropriately. Additionally, landowners must make 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, which must be determined by an independent engineer. Acceptable forms of financial assurance include bonds, letters of credit, or parent company guarantees. The financial assurance must be maintained throughout the duration of the agreement and cannot be canceled until the grantee has fulfilled their decommissioning obligations. The Act aims to protect landowners and ensure that solar facilities are responsibly decommissioned, with an effective date set for November 1, 2025.
