Copenhagen Infrastructure Partners has acquired full ownership of the 1GW Beehive battery energy storage project in Peoria, Arizona, from EDF power solutions North America.
The 250MW four-hour facility is under construction and is expected to enter service in the first half of 2026, CIP said.
Beehive will operate under a 20-year tolling agreement with Arizona Public Service Company, serving about 1.4 million homes and businesses in 11 counties.
The project will take in energy from the grid during periods of high renewable output and discharge power at peak demand, supporting APS in meeting 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.
EDF power solutions said Beehive is its second stand-alone storage project, reinforcing its commitment to BESS technology as a complement to its renewables business.
“EDF power solutions actively seeks partnerships across all stages of a project’s lifecycle, with an eye toward both optimising our portfolio and maximising value creation,” said Ryan Pfaff, executive vice president for grid and distribution-scale power.
CI V, which is investing in the project, reached final close in March 2025 with more than $14bn committed to energy infrastructure in North America, Europe and Asia Pacific.
