ESS Tech (NYSE: GWH) and Burbank Water and Power have announced a new agreement for ESS to deliver a utility-scale battery storage project in California. Under terms of the agreement, the company will install a 75 kW / 500kWh ESS Energy Warehouse™ connected to a 265 kW solar array on the BWP EcoCampus.

Manufactured in the United states, the company says that the iron flow battery will support increased use of renewable power and allow for excess renewable energy to be stored as a baseload energy for Burbank, which it says will improve the resilience and reliability of the grid.

Hugh McDermott, ESS Senior Vice President of Business Development and Sales stated: “ESS is pleased to partner with Burbank Water and Power to deploy the first long-duration energy storage project in the city. BWP is demonstrating the central role that energy storage will play in a decarbonized grid – supporting increasing amounts of renewable energy and enhancing operational resilience.”

Long-duration energy storage will play a critical role in achieving California’s ambitious decarbonization goal: 100% zero-emission electricity by 2045, which the state estimates will need nearly one gigawatt hour of long duration storage by 2030.

ESS Tech’s mission is to accelerate global decarbonization by providing safe, sustainable, long-duration energy storage that powers people, communities and businesses with clean, renewable energy anytime and anywhere it’s needed.
