Excelsior Energy Capital-backed developer Lydian Energy has brought its 150MW/600MWh Faraday battery energy storage system (BESS) project in Utah County, Utah, US into commercial operation.
Announced on 10 November, the standalone, 4-hour duration lithium iron phosphate (LFP) system is contracted under a Schedule 34 agreement to support Meta’s Eagle Mountain data centre operations.
It delivers its contracted storage capacity to utility PacifiCorp under a long-term energy storage agreement (LTESA), supporting grid reliability in Utah.
Faraday BESS occupies an approximately eight-acre site next to Lydian’s 525MW Faraday solar facility and shares its substation and interconnection infrastructure.

Lydian said it took the BESS from mobilisation to commercial operation in about ten months, while construction continued through a June wildfire that threatened the area. Over its lifetime, the project is expected to generate around US$9 million in property tax revenue.
The commercial operation milestone follows Lydian’s February 2026 announcement that it had secured US$689 million in financing for Faraday BESS and two solar projects: AC Ranch 1 in New Mexico and Yellow Viking in Texas.
Supported by Canadian Imperial Bank of Commerce (CIBC) and MUFG Bank, the full-stack financing included a construction-to-term loan, a tax credit bridge loan, a co-investment bridge loan, and a letter of credit facility.
At the time, Faraday BESS Phase 1 was described as a 150MW/733MWh system backed by a long-term power purchase agreement (PPA) with an investment-grade off-taker. PacifiCorp’s 2025 Integrated Resource Plan (IRP) for Utah had also listed a PPA for the project.
Lydian, which officially launched in 2024 with backing from Excelsior Energy Capital, has continued to expand its storage portfolio.
In July 2025, the company closed a US$233 million project financing for three BESS projects in Texas: the 150MW/391MWh Headcamp BESS, the 200MW/521MWh Crane BESS, and the 200MW/521MWh Pintail BESS, all supplied by lithium-ion battery manufacturer CATL.
Separately, parent company Excelsior signed a 7.5GWh supply deal with LG Energy Solution in December 2024 for domestic-content-qualifying BESS, with LG ES subsequently starting manufacturing of LFP cells across 17GWh of US production capacity, which the South Korean manufacturer continues to ramp up.
Lydian is also developing a second phase at the Utah site, Faraday BESS 2, which would add up to 375MW/1,500MWh of storage capacity, with a targeted in-service date of Q4 2028.
