HB 1373 Summary

• Establishes the Commercial Solar Facility Decommissioning Act to govern removal and restoration of commercial solar power facilities in Oklahoma, applying only to facilities that are generation assets.

• Requires grantees (solar facility operators) to remove all solar equipment, foundations to a depth of at least 3 feet, buried cables, and overhead lines, with landowners able to request removal of roads and restoration of property to tillable condition within 180 days of facility decommissioning notice.

• Mandates solar power facility agreements include financial assurance (parent company guaranty with investment-grade credit rating, letter of credit, bond, or other acceptable form) equal to estimated removal and restoration costs minus salvage value.

• Requires financial assurance amounts be determined by independent professional engineers licensed in Oklahoma, with updated estimates due at the 10-year anniversary and every 5 years thereafter, with costs borne by the grantee.

• Voids any agreement provisions attempting to waive decommissioning duties and allows injunctive relief for violations; financial assurance cannot be cancelled until removal obligations are completed or replaced with equivalent coverage, and remains in place upon ownership transfer.

• Effective November 1, 2025.
