Clearway Energy Group of San Francisco, Calif., announced on Feb. 5, 2026, that it closed financing and began construction on the Spindle Energy Center, a 199 megawatt (MW) energy storage system in Weld County, Colo.

Spindle Energy Center will use American-made two-hour Tesla batteries and store up to 398 MWh of dispatchable power.

Clearway is partnering with Blattner Energy on construction, which will create nearly 80 jobs. Spindle is expected to reach commercial operations in late 2026

"Spindle represents a significant investment in Weld County's energy future, delivering reliable storage and economic benefits to the region," said John Woody, chief development officer. "We are deeply grateful to our partners for their collaboration and look forward to continuing our work with the local community, our customer and lenders."

Spindle is contracted with Xcel Energy's subsidiary in Colorado, Public Service Company of Colorado under a long-term agreement that provides the energy company with dispatchable, reliable power.

To finance the $261 million energy center, Clearway assembled a bank consortium consisting of U.S. Bank National Association, BBVA, KeyBanc Capital Markets, National Australia Bank Limited and Norddeutsche Landesbank Girozentrale.

Spindle is expected to generate more than $12 million in tax revenue over the life of the project.

That money will go toward supporting area hospitals, schools, emergency responders and other public services.

The project has allocated $125,000 in community donations to date, including support for numerous local events, youth programs and the Weld Food Bank.
