Zenobe has connected its 100MW UK battery in Capenhurst, Cheshire, to the grid.
The facility is the largest battery directly connected to the transmission network in Europe, connecting at 275,000 volts, and the first in the world to have a commercial contract to provide reactive power.
The site will provide Merseyside and the surrounding areas with a clean, reliable and secure supply of energy at a lower cost to consumers.
Through enabling more renewable power onto the grid, the project is forecast to save over 1m tonnes of CO2 from entering the atmosphere over the next 15 years.
James Basden, co-founder and director of Zenobe, said: “With Capenhurst, we’re solving a key issue on the grid in the Merseyside region while significantly enhancing the nation’s use of renewable power. This pioneering project enables us to deliver vital grid services without the need for fossil fuels, supporting cities like Liverpool with their zero carbon targets.
“The activation of the site represents a key milestone for Zenobe as a business and for the UK as it moves towards a zero-carbon power system. Decarbonisation is more important than ever, as we face increasing energy prices and seek greater energy independence. We look forward to taking these solutions into other countries, using our expertise to make clean power accessible across the globe.”
