e-STORAGE, part of Canadian Solar’s majority-owned subsidiary CSI Solar, has agreed to deliver a 100MW/576 megawatt hours (MWh) direct current (DC) battery energy storage system (BESS) for Strata Clean Energy’s White Tank battery project in the US state of Arizona.
The project aims to enhance grid reliability by delivering stored renewable energy to Arizona Public Service (APS).
Utilising its SolBank 3.0 BESS technology, e-STORAGE will supply, commission and manage the long-term operation of the battery system under a battery supply agreement and long-term service agreement (LTSA) with Strata Clean Energy.
120 SolBank 3.0 battery enclosures will dispatch renewable energy from midday to early evening, aligning with peak customer demand.
e-STORAGE president Colin Parkin 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 US market.”
Construction is scheduled to commence in October 2026, with e-STORAGE managing the system under the 20-year LTSA upon completion.
The agreement ensures optimised system performance, comprehensive monitoring and maintenance, and seamless integration with APS’s energy grid.
Strata Clean Energy president Bob Schaffeld stated: “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.”
In addition, e-STORAGE has recently secured agreements to supply 1.8GWh of battery energy storage systems for two projects by Aypa Power in the US: a 160MW alternating current (AC)/806MWh DC BESS in California and a 200MW AC/998MWh DC BESS in Texas, both expected to begin construction in the third quarter of 2025.
These initiatives will enhance grid resilience and support the integration of renewable energy into key US markets.
