Eos Energy Enterprises Connecting Zinc-Based Battery Storage with Two IPP Customers
Zinc-based battery storage firm Eos Energy Enterprises is advancing supply projects which could exceed 1 GWH of capacity with two independent power producers across the U.S.
Eos Energy Enterprises signed a strategic coloration agreement with Talen Energy Corp. to develop energy storage capacity that can help meet growing demand for artificial intelligence (AI) infrastructure in Pennsylvania. The partnership will focus on leveraging Eos’ American-made Z3 battery technology and Talen’s generation portfolio in Pennsylvania to deliver power while advancing the Commonwealth’s clean energy transition.
Both the companies are looking to develop energy generation and storage capacity to improve grid reliability and release greater capacity utilization from existing assets, effectively generating more electrons from the same infrastructure.
As part of the pact, Eos and Talen will jointly identify and develop multiple storage projects across Talen’s existing assets, including potential sites in Pennsylvania at or near operating Talen plants and retired fossil fuel plants, representing multiple GWh of capacity to meet increasing electricity demand driven by planned AI and cloud computing growth in the Keystone State.
“Our collaboration with Talen marks a significant milestone for Eos and the broader Pennsylvania energy ecosystem,” said Joe Mastrangelo, Chief Executive Officer of Eos Energy. “By pairing Talen’s operational expertise and infrastructure with Eos’ safe, scalable zinc-based storage technology, we’re demonstrating how American innovation can strengthen grid resiliency, address a national security imperative, and power the next generation of digital infrastructure with urgency.”
Meanwhile, Eos Energy Enterprises also announced a supply agreement for about 750 MWh with MN8 Energy, a renewable company in the United States, to deploy Eos next-generation Z3 energy storage systems supporting a portfolio of projects and providing clean, dispatchable power for large load applications.
The first projects MN8 is considering includes Eos’ Z3 technology which is expected to incorporate 200 MWh of storage systems with 10-hour energy discharge duration, combining solar generation and long-duration storage to deliver round-the-clock renewable power. The supply agreement will bring a reliable, American-made solution to high demand sectors like data centers, commercial and industrial facilities, or manufacturing.
This supply agreement enables MN8 to pursue opportunities to deploy Eos’ zinc-based Z3 systems across its energy portfolio within the PJM Interconnection and other U.S. markets with the goal of providing long-duration energy storage capabilities to meet enterprise customers’ increasingly sophisticated requirements. Together, MN8 and Eos are demonstrating how domestic manufacturing and advanced storage technology can deliver power that enhances grid reliability and national security.
“The agreement with MN8 marks another major milestone in Eos’ commercial momentum and demonstrates continued confidence in our technology and our domestic manufacturing capability,” said Justin Vagnozzi, Eos Senior Vice President of Global Sales. “Together with MN8, we’re delivering long-duration storage that supports a stronger and more reliable energy system built here in America.”
Zinc-based battery storage reportedly can offer longer duration backup assets as an alternative to the predominant lithium-ion and lithium iron phosphate battery chemistries.
