Standalone four-hour system adds 600 MWh of contracted storage capacity

Lydian Energy ("Lydian"), an Excelsior Energy Capital-backed developer, owner, and operator of energy infrastructure projects, today announced that its Faraday battery energy storage system (BESS) in Utah County, Utah, has reached commercial operation. The 150 MW/600 MWh project began operating on September 18, 2026. Faraday is contracted via a Schedule 34 contract in support of Meta's Eagle Mountain data center operations.

A standalone, four-hour lithium-iron-phosphate (LFP) battery system, Faraday BESS delivers 600 MWh of contracted storage capacity to PacifiCorp under a long-term energy storage agreement, supporting grid reliability in Utah. The project is situated on an approximately eight-acre site adjacent to the 525 MW Faraday solar facility and shares that facility's substation and interconnection, allowing Lydian to add storage using existing infrastructure. Lydian took Faraday BESS from mobilization to commercial operation in approximately 10 months. Faraday BESS is expected to pay approximately $9 million in property tax over the course of the project life.

"Faraday BESS shows what a mature platform like Lydian's can deliver," said Kim Smith, Chief Operating Officer of Lydian. "Bringing it online on an extremely tight timeline took close coordination across our own team and our supply chain, construction, and financing partners, from acquisition through commissioning. When a wildfire threatened the area in June, our team put safety first while keeping the project on track. Faraday BESS enhances PacifiCorp’s reliable, contracted capacity for Utah customers."

"Storage is an essential part of a resilient grid. It gives utilities the flexibility to respond when conditions change, from extreme weather to unexpected outage," said Amanda Yang, Director of Clean and Renewable Energy at Meta. "Our investments in new energy resources are helping projects like Faraday BESS reach the grid, and that's a role we want to keep playing as we support our Eagle Mountain Data Center.”

"Excelsior backed Lydian because we recognized that a disciplined, execution-driven team could build a leading energy infrastructure platform," said Chris Moakley, Managing Partner at Excelsior Energy Capital and Chair of the Board of Lydian Energy. "As demand for reliable, domestically produced power continues to grow, storage projects like Faraday BESS will play a larger role in keeping the grid dependable."

The completion of Faraday BESS draws on Lydian's integrated platform, which spans development, capital markets, and project delivery. Lydian is also developing Faraday BESS 2 at the Utah site, which would add up to 375 MW/1,500 MWh of storage with a targeted in-service date of the fourth quarter of 2028.
