Eos Energy Enterprises Announces First Purchase Order Under Frontier Power USA's 2 GWh Capacity Reservation Agreement
PITTSBURGH, Pa., June 18, 2026 (GLOBE NEWSWIRE) -- Eos Energy Enterprises, Inc. (NASDAQ:EOSE) ("Eos" or the "Company"), America's leading innovator in designing, manufacturing, and providing zinc-based long-duration energy storage (LDES) systems sourced and manufactured in the United States, today announced the first purchase order under the 2 GWh capacity reservation agreement with Frontier Power USA Parent, LLC (FPUSA). The order supports FPUSA's Redbird project, a 100 MW / 400 MWh battery energy storage system using Eos' Z3™ technology.
Developed by Bimergen, and previously by Bridgelink, for the Electric Reliability Council of Texas (ERCOT) market, the Redbird project was previously approved under a Joint Development Agreement with Eos, with Eos' Z3™ technology selected for deployment. As previously announced, FPUSA and its affiliates have acquired and will provide 100% of the equity for construction of the Redbird project. Bimergen retains a minority economic interest and will collaborate with FPUSA to bring the project into 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. That is what FPUSA was built to do, and the Redbird conversion is one of the first to prove it out."
This order reinforces the strength and scalability of the FPUSA model: converting long-standing developer relationships into a high-quality, late-stage pipeline and deploying capital to bring projects that use Eos technology into operation.
"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. "Combining proven technology with committed capital converts projects like Redbird into operating assets."
Designed as a four-hour system, Redbird is expected to provide dispatchable storage capacity in ERCOT, supporting energy shifting, ancillary services, and overall grid reliability. The project meets rising demand for long-duration storage built for safety, reliability, and domestic supply chain strength, and is positioned to serve forecasted load growth and ERCOT market requirements.
"FPUSA was created to bridge the gap between project development and execution," said Aaron Maczonis, Managing Director, Cerberus Capital Management. "FPUSA is building relationships with leading developers, assembling a portfolio of high-quality projects, and providing access to the capital needed to bring them online."
As part of the acquisition and purchase order by FPUSA and its affiliates, the Redbird volume will be applied against the 2 GWh firm capacity reservation agreement between FPUSA and Eos. In addition, with this order, the Company has now fulfilled nearly 50% of the 1 GWh Bridgelink master supply agreement (MSA), while further advancing an additional development pipeline of 12 GWh across ERCOT, PJM, CAISO, and MISO.
