OK HB1373

Creates the "Commercial Solar Facility Decommissioning Act" requiring solar power facility lease agreements to include provisions making the grantee (non-utility solar operator) responsible for removing all equipment upon decommissioning

Mandates removal of solar devices, transformers, substations, and buried cables to at least 3 feet below surface grade, with holes filled using similar soil types; landowners may also request road removal and restoration to tillable condition within 180 days of decommissioning notice

Requires grantees to provide financial assurance (parent company guaranty, letter of credit, bond, or other acceptable form) covering the estimated removal and restoration costs minus salvage value, as determined by an independent Oklahoma-licensed professional engineer

Financial assurance must be delivered by the earlier of agreement termination or the 20th anniversary of commercial operations, with updated cost estimates required at year 10 and every 5 years thereafter

Agreement provisions waiving landowner rights or exempting grantees from Act requirements are void; effective November 1, 2025
