Copenhagen Infrastructure Partners (CIP), through its fifth flagship fund CI V, and EDF Power Solutions North America announced today that CIP has acquired full ownership of the 1 gigawatt-hour (GWh) Beehive Battery Energy Storage System (BESS) in Peoria, Arizona.
Beehive is a 250 MW / 4-hour duration (1,000 MWh) storage project, construction of which began earlier this year under EDF Power Solutions. CIP will now oversee the project through completion, with commercial operations expected in the first half of 2026.
The project is backed by a 20-year tolling agreement with Arizona Public Service Company (APS), the state’s largest energy provider, serving 1.4 million customers across 11 counties. Beehive will charge during periods of high renewable generation and discharge during peak demand, strengthening grid reliability while supporting APS in meeting its rising capacity needs.
“With electricity demand rapidly increasing in the Southwest, we anticipate battery storage will play a critical role in powering innovation and economic growth,” said Tim Evans, Partner and Head of North America at CIP. “Beehive will provide reliable energy and grid services to customers in Arizona and build on CIP’s track record of developing, constructing, and operating energy infrastructure investments across the country. We are pleased to have worked with the EDF power solutions team.”
