Bill No. 1373, known as the "Commercial Solar Facility Decommissioning Act," establishes regulations for the decommissioning of commercial solar facilities in Oklahoma. The bill defines key terms related to solar power facilities, including "generation assets," "grantee," and "solar power facility agreement." It mandates that any agreement between a landowner and a grantee must include specific provisions regarding the removal of solar facilities, the restoration of the land, and the financial assurance required to cover the costs associated with these obligations. Notably, any provision in a solar power facility agreement that attempts to waive rights or exempt a grantee from liability under this act is deemed void.

The act also outlines the requirements for financial assurance, specifying acceptable forms and the minimum amount needed to ensure the grantee's obligations are met. The grantee is responsible for obtaining and delivering this financial assurance to the landowner, with regular updates on estimated removal costs and salvage values provided by an independent engineer. Additionally, the bill prohibits the cancellation of financial assurance until the grantee has fulfilled their decommissioning responsibilities, ensuring that landowners are protected throughout the process. The act is set to take effect on November 1, 2025.
