Oklahoma State Solar Policy Resources

 

Oklahoma Energy Storage Policy and Market Overview

Oklahoma is undertaking a comprehensive approach to expanding the energy storage market and grid capacity. The state is positioning policy actions to align with renewable energy-plus-storage procurement and reducing energy curtailment.

Utility procurement is leading the battery storage deployment in Oklahoma. NextEra Energy Resources currently operates the only grid-scale storage facility in the state with a capacity of 200 MW. Oklahoma is also committed to investing in the energy storage economy on the manufacturing front. State legislation has outlined energy storage goals and codified state commitments to becoming a clearinghouse for the four “Rs” of battery storage: repairing, refurbishing, repurposing, and remanufacturing. Oklahoma offers opportunities to interconnect storage systems with renewable energy, cultivate a circular economy, and pursue wide-scale grid reliability and resiliency.
