Strata Clean Energy, a grid-scale renewable energy solutions provider, broke ground on its 255 MW Scatter Wash battery storage complex in Phoenix, Arizona. Once operational in April 2025, the project’s batteries will store enough electricity to power over 250,000 homes for 4 hours daily for 20 years.

The Scatter Wash facility will effectively provide Arizona Public Service (APS) customers with reliable energy while supporting increasing power demands and storing significant amounts of renewable energy from solar power plants on the grid to use when needed. This will be particularly helpful to APS in the summertime when extreme heat and electricity demand are high throughout the state.

The facility will utilize Tesla’s Megapack 2XL, a fully integrated battery system that features advanced battery technology, software, and power conversion systems. These battery systems will efficiently store and dispatch electrical energy to and from the grid during optimal periods.

“Arizona is one of the fastest growing states in the country, and reliable and affordable power is critical for APS customers, especially during our hottest summer days,” said Jacob Tetlow, Executive Vice President of Operations at APS. “These batteries will help us continue to serve our customers with a balanced and diverse power supply.”

Strata entered into a 20-year tolling agreement with APS for the Scatter Wash battery storage complex in 2023 to help meet the growing needs of residential and business customers with affordable, reliable, and clean electricity.

Under the agreement, Strata will build, own, and operate the battery storage complex as part of the firm’s portfolio of clean-energy assets.

The Scatter Wash facility is also supported by the Investment Tax Credit for standalone energy storage created by the Inflation Reduction Act of 2022.
