Gore Street completes energisation of 400 MWh US battery storage system

Gore Street energises Big Rock, a 200 MW / 400 MWh battery in California, raising its total capacity to 621.4 MW / 792.1 MWh.

Gore Street Energy Storage Fund has completed the energisation of Big Rock, a 200 MW / 400 MWh battery storage project in California, increasing the fund’s total energised capacity to 621.4 MW / 792.1 MWh across five grids.

Big Rock, Gore Street’s largest asset to date, represents a 47% boost in its energised capacity. The project has secured a 12-year fixed-price Resource Adequacy (RA) contract valued at over $165 million. The RA is stackable, allowing multiple revenue streams. While RA revenue begins in June 2025, the asset is expected to generate merchant revenue earlier.

Big Rock is also eligible for an investment tax credit (ITC) of up to 30% of qualifying capital expenditures under the Inflation Reduction Act.

Meanwhile, construction at Dogfish, a 75 MW / 75 MWh asset in Texas, is progressing well, with major cabling work complete and energisation on track for February. However, the 57 MW / 57 MWh Enderby project in the UK has been delayed due to last-minute transformer inspections required by National Grid Electricity Transmission (NGET). Gore Street is working with suppliers to complete energisation in the coming weeks.

Alex O’Cinneide, CEO of Gore Street Capital, stated: “With Enderby and Dogfish set to energise soon, our portfolio is on track to reach 753.4 MW / 924.1 MWh. We expect this to drive increased revenue and free cash flow to support dividend cover.”
