Strata Clean Energy has broken ground on its 255MW/1020MWh Scatter Wash battery storage complex in Phoenix, Arizona.
The facility is expected to become operational in April 2025. The project’s batteries can store enough electricity to power more than 250,000 homes for four hours daily for 20 years.
Scatter Wash will provide APS customers with reliable energy, support increased power demand, and store significant amounts of renewable energy from solar power plants on its grid to use when it is needed, particularly in the summertime when extreme heat and electricity demand is high in Arizona.
Tesla’s Megapack 2XL, a fully integrated battery system featuring advanced battery technology, software, and power conversion systems, will be used throughout the project. These battery systems will efficiently store and dispatch electrical energy to and from the grid during optimal periods.
“This groundbreaking demonstrates a considerable advancement in large-scale sustainable energy solutions in a major growing metropolitan area, underscoring Strata’s dedication to addressing critical grid challenges,” said Strata Clean Energy president Josh Rogol.
“In showcasing our dedication to utility clients like APS and Arizona homes and businesses, we continue shaping the future of energy storage by ensuring grid reliability and driving progress towards broader decarbonization and economic development goals through local jobs and investment. It exemplifies our dedication to a more sustainable future.”
