Redflow batteries approved for 20MW Californian project

June 6, 2023

Redflow’s flow batteries have been funded and approved by the California Energy Commission (CEC) for a large-scale solar and storage project, which will provide power for the Paskenta Band of Nomlaki Indians.

The 20 MWh system will be one of the “largest zinc-based battery projects in the world”, Redflow said, and will represent the company’s largest single sale and deployment of batteries globally to date.

With this project, Redflow joins a small number of commercially proven non-lithium storage providers that the CEC is funding, as it looks to compile a robust portfolio of long-duration energy storage projects. The projects represent a key step to help address an estimated 45-55 GW of long-duration energy storage required in California by 2045 to support grid reliability and the state’s clean energy transition targets.

The project will be funded by the CEC’s US$140 million long-duration energy storage grant program focused on enabling commercially proven non-lithium energy storage technologies to scale.
