Canadian Solar Inc. announced that e-STORAGE, part of its majority-owned subsidiary CSI Solar Co., Ltd., has signed a Battery Supply Agreement and Long-Term Service Agreement (LTSA) with Strata Clean Energy’s White Tank Energy Storage LLC. The project involves building a 100 MW / 576 MWh DC Battery Energy Storage System (BESS) in Arizona, USA, with construction set to begin in October 2026.
The White Tank Battery project, developed by Strata Clean Energy, will store renewable energy and supply it to Arizona Public Service (APS), enhancing grid reliability by balancing energy supply and demand. e-STORAGE, a leading global provider of energy storage solutions, will deliver, install, and manage the system using its advanced SolBank 3.0 technology.
Bob Schaffeld, President of Strata Clean Energy, said in a statement, “Strata is pleased to announce the inclusion of e-STORAGE’s flexible, turnkey solutions and service support in our White Tank energy storage project. Their commitment to performance excellence aligns perfectly with our mission to deliver only the best quality to our customers.”
Colin Parkin, President of e-STORAGE, stated, “We are proud to partner with Strata Clean Energy on the White Tank Battery project, which 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. e-STORAGE remains committed to driving energy innovation and delivering best-in-class solutions for the U.S. market.”
As part of the agreement, e-STORAGE will provide around 120 SolBank 3.0 battery enclosures to help store excess renewable energy generated during the day and release it in the evening when demand is higher. After the system is commissioned, e-STORAGE will oversee operations under a 20-year LTSA, ensuring optimal performance, regular maintenance, and smooth integration with APS’s energy grid. This project highlights Canadian Solar’s ongoing commitment to advancing clean energy solutions and strengthening grid stability through cutting-edge technology.
