Safe and sustainable energy storage solution is first utility-scale deployment for BWP

WILSONVILLE, Ore.--(BUSINESS WIRE)-- ESS Inc. (“ESS”) (NYSE: GWH), a leading manufacturer of long-duration iron flow batteries for commercial and utility-scale energy storage applications, and Burbank Water and Power (BWP) in California have entered into an agreement for ESS to deliver BWP’s first utility-scale battery storage project. Under the agreement, a 75 kW / 500kWh ESS Energy Warehouse™ will be installed and connected to a 265 kW solar array on the BWP EcoCampus.

The iron flow battery will support the increased use of renewable power and allow excess renewable energy to be stored and used as baseload energy for Burbank, improving the resilience and reliability of the grid. ESS iron flow battery technology is safe and non-toxic, offers a 25-year lifespan without capacity degradation, and is manufactured in the United States using domestically sourced, earth-abundant materials.

“ESS is pleased to partner with Burbank Water and Power to deploy the first long-duration energy storage project in the city,” said Hugh McDermott, ESS SVP of Business Development and Sales. “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. We look forward to working with them to achieve their ambitious climate goals.”

“BWP is already using small-scale battery technology at our substations, but we see the value in adding considerably more storage to the network. This initiative will be the largest battery installed in Burbank, providing enough renewable power for 300 homes annually,” says Mandip Samra, Assistant General Manager for Power Supply at BWP. “The project is a big step forward to help meet our goal of having a greenhouse gas-free power supply by 2040 and providing energy storage for Burbank now and for decades to come.”

Long-duration energy storage will play a critical role in achieving California’s ambitious decarbonization goal: 100% zero-emission electricity by 2045. The California Energy Storage Alliance (CESA) estimates that the state will need nearly one gigawatt-hour (1000 MWh) of long-duration storage by 2030 to integrate intermittent renewable energy and optimize assets for a cleaner, more affordable and reliable grid.

The ESS Energy Warehouse™ is expected to be installed in Burbank by December 2023.
