Built with union labor in Alameda County, the 100 MWac project now serves Ava Community Energy and CleanPowerSF

LIVERMORE, Calif., Oct. 9, 2026 — IPX Power, LLC (“IPX Power”) today announced that its Aramis Solar Energy Generation and Storage Project in unincorporated Alameda County has begun delivering power to Ava Community Energy and CleanPowerSF. The project reached commercial operation Aug. 20 and began deliveries under contract Oct. 1.

Aramis pairs 100 MWac of solar capacity with an integrated 400 MWh battery storage system. The batteries charge during the day and send power to the grid in the evening, when demand peaks. Aramis can power 36,000 homes annually or discharge enough power to support up to 74,000 homes for four hours.

“Most projects this size are built far from the people who use the power. Aramis is different,” said David Brochu, CEO of IPX Power. “Built by a union workforce right here in Alameda County, this is clean, reliable Bay Area power for Bay Area customers.”

Construction began in May 2025 under a five-craft project labor agreement and peaked at about 500 union workers. Aramis was built with American-made solar panels and batteries, including roughly 226,000 First Solar modules and 118 Tesla Megapack units. The project supports four permanent operations positions.

Aramis generated more than $7.6 million in local sales tax revenue during construction and will contribute about $475,000 a year in property taxes to Alameda County, more than $4.7 million over its first 10 years.

“Ava celebrates the launch of Aramis, Alameda County’s largest solar and battery storage project,” said Howard Chang, CEO of Ava Community Energy. “Aramis reflects our commitment to developing local clean energy projects and creating good green-economy jobs. The resource adequacy Ava receives from the project will help us continue delivering clean, reliable energy at competitive rates to our customers across Alameda and San Joaquin counties.”

“This project is helping CleanPowerSF, San Francisco’s community energy program, supply more of our renewable power from generating resources located right here in the Bay Area. It also helps us make better use of that power throughout the day,” said SFPUC Assistant General Manager Michael Hyams. “Battery storage allows us to use that clean energy after the sun goes down, improving the reliability and environmental performance of power supply in our region. Aramis has also been a strong community partner, donating more than $260,000 through our Social Impact Partnership for energy cost reduction programs for nonprofits.”

“IPX Power believes that clean energy is about more than producing electricity. It’s about empowering the communities where we work” said Micah Day, community engagement manager at IPX Power. “We strive to build long-term, authentic relationships with our neighbors, and to provide meaningful resources to the organizations that are making a difference in these communities.”

IPX Power’s long-term commitment to the Tri-Valley region includes supporting 15 local organizations working in education, health, food security, and sustainability. Additionally, IPX Power has established a Donor Advised Fund at Three Valleys Community Foundation ensuring continued impact for years to come.

IPX Power marked the milestone with a ribbon cutting at the project site Oct. 1. Speakers included Alameda County Supervisor David Haubert, Ava Community Energy CEO Howard Chang, San Francisco Public Utilities Commission Assistant General Manager Michael Hyams, and Three Valleys Community Foundation President and CEO Dr. Kelly Bowers.
