Eos Energy Enterprises (NASDAQ: EOSE) announced the first purchase order under a 2 gigawatt-hour capacity reservation agreement with Frontier Power USA Parent, LLC (FPUSA), supporting the Redbird project, a 100 MW / 400 MWh battery energy storage system in the ERCOT market.

The Redbird project, developed by Bimergen (NYSE American: BESS) and previously by Bridgelink, will use Eos' Z3™ technology and is designed as a four-hour storage system intended to provide dispatchable capacity in ERCOT. FPUSA and its affiliates have acquired the project and will provide 100% of the equity for construction. Bimergen retains a minority economic interest and will collaborate with FPUSA on bringing the project to commercial operation.

"Redbird did not happen overnight. It came from years of working with Bimergen to move projects under active development toward execution," said Nathan Kroeker, Chief Commercial Officer of Eos. "What FPUSA adds is the capital to turn opportunities into operating assets."

"We developed Redbird to address growing demand for dispatchable storage in ERCOT and selected Eos because Z3™ is purpose-built for the multi-hour applications the market requires," said Cole Johnson, Co-Chief Executive Officer of Bimergen Energy.

The Redbird volume will be applied against the 2 GWh firm capacity reservation agreement between FPUSA and Eos. With this order, Eos states it has fulfilled nearly 50% of a separate 1 GWh Bridgelink master supply agreement, while reporting an additional development pipeline of 12 GWh across ERCOT, PJM, CAISO, and MISO markets.

FPUSA is affiliated with Cerberus Capital Management. Aaron Maczonis, Managing Director at Cerberus, said the platform was "created to bridge the gap between project development and execution."
