ESS Inc., a manufacturer of long-duration iron flow batteries, will install a 75 kW / 500kWh ESS Energy Warehouse system and connect it to an existing 265 kW solar array on the EcoCampus of the Burbank Water and Power (BWP) utility in California.

The new utility-scale battery storage system will be a useful addition to the EcoCampus, which already uses sustainable landscape technologies and energy-efficient lighting.

The ESS Energy Warehouse is a safe and non-toxic battery technology, using only iron, salt and water. It has a 25-year life, ensuring electricity storage without capacity fade. The battery is manufactured in the U.S. and does not use rare earth minerals.

This will be the largest battery installed in Burbank. It will store and supply sufficient energy to power 300 homes annually, said 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," Samra added. 

The California Energy Storage Alliance expects the state will require an estimated one gigawatt-hour (1000 MWh) of long-duration storage by 2030 to integrate intermittent renewable energy.

“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,” Hugh McDermott, ESS SVP of Business Development and Sales, said.

Installation of the ESS Energy Warehouse is expected to be complete by December 2023.
