Clēnera, an Enlight company, entered into a 20-year power purchase agreement (“PPA”) with Arizona’s largest utility, Arizona Public Service’ (APS), for solar and battery storage services at the CO Bar complex outside of Flagstaff.

The agreement calls for 258 megawatts (MW) of solar and 824 megawatt-hours (MWh) of battery storage, Englight said in an Aug. 30 press release.

The CO Bar complex is a landmark solar and storage complex being developed by Clēnera, a subsidiary of Enlight Renewable Energy, the company said. The complex comprises a total of 1.2 gigawatts and 824 MWh of battery storage and is expected to be one of the largest renewable energy installations in the U.S.

“We are excited to work with APS to develop the first combined solar and storage project at the CO Bar complex and help drive Arizona’s clean energy initiatives to deliver affordable, clean power to households in the state,” said Gilad Yavetz, CEO of Enlight.

The agreement with APS is the third power purchase agreement signed at the complex and the first to provide battery storage. With the agreement, the entire complex is contracted to provide power to Arizona’s leading utilities. The complex is scheduled to commence construction by the end of the year and to reach operations during 2025.
