U.S.-based Eos Energy Enterprises, Inc., a company specialising in zinc-based energy storage systems, has announced a strategic partnership with independent power producer Talen Energy Corporation. The initiative aims to deploy energy storage capacity across Pennsylvania to meet increasing electricity demand linked to the expansion of AI-powered data centres.
Deployment of projects at existing sites
The two companies plan to identify and develop several storage projects on sites owned by Talen Energy. These locations include operational power plants and retired fossil fuel facilities, all located in Pennsylvania. The targeted capacity represents several gigawatt-hours (GWh), intended to optimise use of existing assets while enhancing grid reliability.
Locally developed zinc-air storage technology
The partnership relies on Eos’ Z3 technology, a zinc-based storage solution designed to provide safety, duration, and reliability. Manufactured in the United States, this technology uses over 90% domestically sourced components. It is designed to absorb energy demand spikes caused by power-intensive applications such as AI servers, while reducing dependence on imported lithium batteries.
Strengthening digital infrastructure
Executives from both companies highlighted the strategic relevance of the initiative to support the expansion of the digital economy. Increasing available electrical capacity will ensure reliable power for cloud computing infrastructure while enabling more effective integration of low-carbon energy sources into the regional grid.
Replicable capacity and local industrial footprint
The companies present the model as replicable nationwide, combining existing generation facilities with long-duration storage technologies. This strategy could rapidly address rising power consumption while reinforcing local supply chains.
