Canadian Solar has announced that its subsidiary e–Storage has signed a battery supply agreement and long-term service agreement (LTSA) with Strata Clean Energy’s White Tank Energy Storage LLC for a 100 MW/576 MWh DC battery energy storage system in Arizona. Construction is set to begin in October of 2026.

The White Tank project will deliver stored renewable energy to Arizona Public Service, utilising 120 of its proprietary SolBank 3.0 BESS technology. E–Storage will supply, commission, and oversee the long-term operation of the battery system.

Following commissioning, e-Storage will manage the system under a 20-year LTSA, with the aim of ensuring optimised system performance, comprehensive monitoring and maintenance, and seamless integration with APS’s energy grid.

Colin Parkin, president of e-Storage, commented: “White Tank … will play a crucial role in supporting Arizona’s clean energy goals. Our SolBank technology is designed to deliver safe, high-performance energy storage solutions that meet the growing demand for reliable, dispatchable renewable energy.”
