The Big Rock energy storage project, located in Imperial County, will provide resource adequacy (RA) and ancillary services to the CAISO market, adding to the 5.6 GW of energy storage already in place. Big Rock will be operated at 100 MW of deliverability to supply 400 MWh and meet the four-hour discharge needs of an RA contract.
Is big Rock a Gore Street Energy Storage fund investment?
Big Rock joins other energy storage investments by the Gore Street Energy Storage Fund in Texas, Ireland, Great Britain, and Germany. “The Big Rock project marks GSF’s most recent acquisition, and the company’s biggest to date,” said Alex O’Cinneide, CEO of Gore Street Capital.
How much power does Big Rock have?
Big Rock will be operated at 100 MW of deliverability to supply 400 MWh and meet the four-hour discharge needs of an RA contract. The project is being developed by Gore Street Energy Storage Fund, which acquired the site in February 2023 from Avantus, which will continue to provide administrative and development services for the installation.
How much power does a big rock battery store?
The Big Rock units have a power rating of 1.5 MW and can store 3.5 MWh. Along with tier-1 lithium-ion batteries, the 137 containers include over 1,300 of LS-ES’s modular 140 kVA AiON-SIS string inverters installed inside an air-cooled section of the container, together with a liquid-cooled DC battery compartment.
How does the Aion-ESS big rock installation work?
As with other AiON-ESS Energy Series installations, the Big Rock installation will integrate DC and AC components inside each container and provide AC output ready to be fed into medium voltage transformers.
