Chinese-owned Canadian Solar (CSIQ) has secured an agreement to develop what would be the largest standalone battery in Arizona, in the latest evidence that the US standalone battery market is growing. Under a 20-year tolling agreement with Arizona Public Service Company (APS), CSIQ’s Recurrent Energy will construct, own and operate the 1,200 MWh Papago Storage project that is expected to dispatch enough power for approximately 244,000 homes for four hours every day, the Chinese company said last week. Construction of Papago Storage is expected to begin in the third quarter of 2024, with commercial operation planned in the second quarter of 2025. The Papago Storage project will “complement Arizona's growing solar energy capacity,” said CSIQ, noting that APS has committed to supply its customers with 100% clean and carbon-free energy by 2050.
