Project Overview

The 250 MW / 2,000 MWh Copper Basin Energy Storage facility will provide energy and capacity services to the SRP grid, enhancing grid reliability and accelerating the integration of locally produced renewable energy. The project will abide by the most stringent design and cutting-edge safety standards to ensure the project maximizes benefits to SRP and the San Tan Valley.

Construction of the Copper Basin facility is anticipated to start in 2029. The 2031 completion of the facility will ensure that SRP meets its reliability needs.

Situated along a major transmission corridor feeding the Abel substation, the site’s location in a commercial zone minimizes environmental impacts. Copper Basin’s site location is optimal for new energy infrastructure as it does not require long transmission lines to connect the facility to the power grid and is complementary to surrounding land uses.
