Energy Storage & Solutions

Arizona’s First Standalone Energy Storage Project

Energy storage is already providing a wealth of services to central Arizona’s grid... from supporting the growth of renewables to boosting reliability on transmission and distribution grids. This latest investment will add needed much-needed efficiency and value for our more than 1 million electric consumers.

The 10-megawatt project, built in Chandler, was procured as part of an SRP initiative to learn more about grid-scale battery storage so that SRP will be better prepared to implement battery storage technology at an even larger scale in the future. The energy storage solution provides peaking capacity that injects power into the grid during high peak demand periods for SRP customers.

Under the 20-year agreement, AES provided SRP with the 10-megawatt, 40 megawatt-hour battery-based energy storage system that is charged by an SRP distribution substation. The solution can deliver the energy equivalent to power about 2,400 homes in the greater Phoenix metropolitan area for up to four hours and will help SRP assess how best to scale up future energy storage projects across its 2,900-square-mile electric service area.

SRP’s new energy storage project marks the latest move to secure resources that enable the integration of more renewables for its electric service area. This comes at a time when Arizona is evaluating steps to transform its energy infrastructure, including proposals for both the largest energy storage target in the United States – three gigawatts by 2030 – and a “clean peak” standard.
