Salt River Project, Plus Power LLC, and officials from the city of Avondale will soon break ground on the new large-scale battery facility, Sierra Estrella Energy Storage.
The facility will store up to 250 megawatts, or 1,000 megawatt-hours, which will serve SRP customers during times of peak electricity demand and facilitate the integration of renewable resources into the SRP power system.
This is enough stored energy to power more than 56,000 average-size homes for a four-hour period.
The Sierra Estrella facility is one of two battery storage projects SRP recently announced with Plus Power that is scheduled to come online by summer 2024.
Plus Power will design, build, and operate the project to updated national codes and standards for Battery Energy Storage Systems, which incorporate lessons learned from incidents at other battery facilities.
