Enel signals Cali battery charge
Three PG&E storage facilities totalling 85MW to be online by 2023
Enel Green Power North America has signed three energy storage agreements with California utility Pacific Gas and Electric (PG&E) totalling 85MW.
Under the terms of the agreements, Enel and Sovereign Energy Storage will build the 50MW Kingston, 25MW Cascade and 10MW Sierra stand-alone lithium-ion energy storage projects in California.
The facilities are expected to be operational by 2023, pending review and approval by the California Public Utility Commission and local and regulatory agencies.
They will connect to PGE&E’s grid and will charge when there is an abundance of renewable energy, Enel said.
“The energy stored in the batteries will then be delivered back to the grid during times of peak demand, increasing grid reliability, while also easing congestion,” it added.
Enel global thermal generation head Enrico Viale said: “The signing of these agreements marks an important step forward in our group’s plan to strengthen its presence in the energy storage market and expand this business in the US, and California in particular, which are at the forefront in the development of this market.”
PG&E signed three more projects alongside the three contracts awarded to Enel for a total capacity of 165MW.
EDF Renewable Energy will develop the 10MW Calstor facility, LS Power has the contract for the 50MW Diablo project and Tesla will build a 20MW plant.
