Eos Energy Enterprises (EOSE) saw its shares increase about 9% on Thursday after the company announced the first purchase order placed under a 2 GWh capacity reservation agreement with Frontier Power USA Parent, LLC.
The order is tied to the Redbird project, a 100 MW / 400 MWh battery energy storage system that will use Eos Energy's Z3 technology. Developed by Bimergen for participation in the Electric Reliability Council of Texas market, Redbird was previously approved under a Joint Development Agreement with Eos. According to the announcement, Frontier Power USA and its affiliates will supply 100% of the equity required for Redbirds construction, while Bimergen will retain a minority economic interest in the project.
Redbird is configured as a four-hour storage asset intended to deliver dispatchable storage capacity within ERCOT. The system is designed to support energy shifting, provide ancillary services, and contribute to on-grid reliability, per the companys description of the project.
Under the transaction, the volume associated with Redbird will be allocated against the 2 GWh firm capacity reservation agreement between Frontier Power USA and Eos. Separately, Eos noted that, with this purchase order, it has satisfied nearly half of a 1 GWh Bridgelink master supply agreement. The company also reported advancement of an additional development pipeline totaling 12 GWh across the ERCOT, PJM, CAISO, and MISO markets.
Eos manufactures zinc-based long-duration energy storage systems in the United States. The Redbird order represents the first firm purchase tied to the Frontier reservation and is presented as part of the companies broader commercial activity across multiple regional power markets.
Summary
The companys first purchase order under a 2 GWh reservation with Frontier Power USA covers the Redbird 100 MW / 400 MWh project in ERCOT, uses Eos Z3 technology, and was followed by a roughly 9% rise in Eos shares. The Redbird volume will be applied to the firm reservation and Eos continues to advance a 12 GWh development pipeline across major U.S. grid regions.
