Redflow Limited announced that the U.S. Department of Energy (DOE) has approved funding for a 34.4 MWh long-duration energy storage (LDES) microgrid project in which Redflow has been named as the battery provider. The project will form part of the DOE's USD 325 million LDES program which seeks to advance critical clean energy technologies, expand the adoption of renewable energy resources, and strengthen America's energy security, announced on September 22. The Children's Hospital Resilient Grid with Energy Storage (CHARGES) project will enable the Valley Children's Hospital in Madera, California to replace diesel generators with cleaner, more cost-effective resources at the hospital facility, and provide a roadmap for hospitals and critical infrastructure throughout the country to implement similar projects.

Redflow will collaborate on the system with its project development partner, Faraday Microgrids. The project is being sponsored, and expected to be co-funded by, the California Energy Commission (CEC).Valley Children's Hospital in Madera is the only full-service pediatric facility in California'sCentral Valley and regularly faces extreme heat conditions, drought, coastal smog, and poor air quality. The 34.4 MWh long-duration energy storage and solar microgrid will enable the hospital to better serve the region's residents, even during power interruptions.

This project also represents an important step toward meeting California's goal of installing 45-55 GW of long-duration energy storage by 2045 to support grid reliability and the clean energy transition. The system is expected to maintain critical hospital operations during utility outages or shortages not attributable to earthquakes. In the event of obligatory natural gas or fuel cell shut-offs during seismic events, the systems will maintain facility operations for at least 18 hours after earthquakes.

In addition to Redflow batteries, the microgrid will be paired with other renewable energy resources to support decarbonization, result in cost savings for the hospital, provide resilient infrastructure for the hospital in case of natural disasters and power outages, and provide overall grid benefits.
