Missouri’s energy storage market remains in an early stage, with limited deployment despite growing solar development across the state.
While solar capacity and investment are increasing, dedicated storage policies and deployment remain limited. As the state continues to expand its renewable energy portfolio, energy storage is expected to play a larger role in supporting grid reliability and future market growth.
