Arizona Republic | SRP deploys state’s largest battery system to handle peak energy demand spikes
Salt River Project is deploying two new industrial-scale battery storage systems, including the state’s largest so far, to absorb excess energy when it’s not needed for release at later periods when demand spikes.
