Okla. Stat. tit. 17 § 801.6
Energy efficiency and demand side management are important components to maximizing the energy resources of our state. Therefore, every electricity generating entity in Oklahoma may use energy efficiency and demand side management measures to assist the state in meeting its renewable energy standard. Provided, however, that demand side management may not be used to meet more than twenty-five percent (25%) of the overall fifteen percent (15%) renewable energy standard for the state. Energy conservation measures shall be described and quantified to the Corporation Commission on March 1 annually. The Commission shall make the final determination of the amount of generation capacity the electricity generating entity conserved and determine to what degree that will count toward meeting the renewable energy standard for the state.
