CSI Solar Co., Ltd.’s e-STORAGE has received a supply and integration contract for 1 GWh DC of energy storage solution named SolBank for the Roadrunner Reserve System project in Arizona, which will be constructed and operated by DEPCOM Power and Tucson Electric Power (TEP), respectively.
With a rated capacity of 200 MW and a total storage capacity of 800 MWh AC, the energy storage project will serve up to approximately 42,000 homes for a four-hour duration once operational.
This is Arizona’s second e-STORAGE project, following the introduction of the Papago Storage project (1,200 MWh / 1,519 MWh DC nominal) in August of 2023. While the Papago project is scheduled to be operational in late 2024, the Road Runner Reserve System project is expected to commence service in the summer of 2025.
“The Roadrunner Reserve System project will contribute to Arizona's growing solar energy capacity and aid the state in meeting surging electricity demand and energy reliability goals,” said Colin Parkin, President of e-STORAGE Business Group.
SolBank uses the safest battery technology with LFP cells, highly efficient liquid cooling systems, and multi-level fire safety management systems. It also includes state-of-the-art monitoring and control systems and an active cell balancing system to ensure safe operation and optimal product performance.
So far, e-STORAGE has implemented over 3.3 GWh DC of battery energy storage solutions across the U.S., Canada, the United Kingdom, and China, bringing the total installed capacity and contracted pipeline to 12.4 GWh DC.
"Battery energy storage systems that offer safe and reliable operation are key to Tucson Electric Power's expansion of clean energy resources," said Eric Bronner, TEP Senior Director of System Integration and Operations.
