Redflow has completed the 2 MWh energy storage system for Anaergia in California. The 2 MWh sale was announced on March 9, 2021. This represents Redflow’s largest single sale of batteries to date. The energy storage system, comprising 192 zinc-bromine flow batteries, has been designed for Anaergia’s Rialto Bioenergy Facility as part of the Facility’s microgrid. The project was funded in part by a grant from the California Energy Commission and consists of the batteries, a biogas conditioning system to support a 2.0MW biogas-fuelled cogeneration unit, and a microgrid control system. The battery system is consisted of 12 x 160 kWh Redflow Energy Pods that are clustered into four strings tied to four 125 kW Dynapower inverters.
Each of the four battery strings has now been successfully charged and discharged and has passed critical acceptance testing criteria. The final test of the entire system will be executed in January – when Siemens integrate the battery into the microgrid controller and the facility can absorb the entire 2 MWh load of the energy storage system. Anaergia has given Redflow approval for full invoicing of the project.
Commenting on the installation, Andrew Dale, the Lead Project Manager for Anaergia, said, “Redflow has completed the deployment of the 2 MWh energy storage system, a major milestone for us both, and we look forward to working with them on future energy storage projects.”
