Sun Streams 3 solar and storage

Sun Streams 3 is the first project at Longroad’s Sun Streams complex that includes battery energy storage. The storage component will provide reliability benefits to the Arizona grid because it will allow solar energy generated during the day to be dispatched in the evenings when it is needed most. The project’s total output will be purchased by Arizona Public Service via a long-term Power Purchase Agreement.
