Eos has announced its intention to move its headquarters to Pennsylvania, US, as well as agreements for potential energy storage projects with Talen Energy and MN8 Energy.
Eos investing US$353 million in US manufacturing expansion and HQ move
US zinc battery storage manufacturer Eos Energy Enterprises is investing US$352.9 million to relocate its headquarters to Pennsylvania from New Jersey.
Eos says it will expand its existing manufacturing operation in Pennsylvania’s Allegheny County, creating and retaining a total of 1,000 jobs.
Pennsylvania is dedicating US$22 million to the project, which is expected to generate at least 735 new jobs and preserve 265 existing positions.

Eos currently leases two facilities in the Allegheny County town of Turtle Creek, where the first phase of the project started in 2024 with the installation of a new, automated production line.
As part of this expansion, the company plans to lease an existing 432,000-square-foot facility in Marshall Township, located in northern Allegheny County, where it intends to add more production lines.
Eos plans to move its corporate headquarters from New Jersey to a 40,000-square-foot office at Nova Place in Pittsburgh’s North Shore neighbourhood in the second half of 2026.
The company emphasises that relocating will enable it to enhance collaborations with universities like Carnegie Mellon, aiming to develop a skilled workforce skilled in robotics, artificial intelligence, computer science, and engineering.
Eos received a funding proposal from the Pennsylvania Department of Community and Economic Development (DCED) for a US$10 million Pennsylvania First grant, along with US$12 million through the Redevelopment Assistance Capital Programme (RACP), which also includes US$3 million awarded to Eos in 2022.
Additionally, the company may qualify for tax incentives such as the Qualified Manufacturing Innovation and Reinvestment Deduction, the Manufacturing Tax Credit, and the Research and Development Tax Credit programmes.
Allegheny County also allocated US$2 million to fund Eos’s relocation and expansion efforts.
These amounts total around US$27 million, representing a small fraction of Eos’s US$352.9 million relocation investment.
Eos reported its Q2 2025 financial results on 30 July, showing that the company has still not reached profitability.
It reported Q2 2025 revenue of US$15.2 million, its highest quarterly figure so far, closely matching the US$15.6 million revenue for 2024. The half-year revenue in 2025 reached US$25.7 million, a 243% increase from the US$7.5 million reported in H1 2024.
The company received funding support from the Biden administration by securing a loan from the US Department of Energy (DOE) Loan Programs Office (LPO) in November 2024.
Based on the milestones achieved, the LPO committed up to US$277 million to support Eos’ manufacturing expansion, with US$68.3 million drawn down by the end of Q2.
Energy-Storage.news asked Eos for comment on how the company plans to fund the investment in Pennsylvania, as well as an update on its loan from the LPO, but did not receive a response by the time of publication.
Eos and Talen Energy to provide energy storage for Pennsylvania data centres
Eos has made further commitments in Pennsylvania, announcing a strategic collaboration with Talen Energy, to develop energy storage capacity across the state to support artificial intelligence (AI) infrastructure.
Under the agreement, Eos and Talen plan to collaborate on identifying and developing several storage projects using Talen’s existing assets.
This includes potential sites in Pennsylvania near current Talen plants and retired fossil fuel facilities, which could add multiple GWh of capacity to support rising electricity demand fueled by anticipated growth in AI and cloud computing.
Eos will use its Z3 zinc battery technology, and Talen will use its generation portfolio under the agreement.
The companies aim to expand energy generation and storage capabilities to improve grid reliability and maximise the use of existing assets.
Eos and MN8 Energy sign supply agreement to deploy up to 750MWh of long-duration energy storage
Eos also announced a supply agreement up to 750MWh of long-duration energy storage (LDES) with MN8 Energy.
The initial projects MN8 would consider using Eos’ Z3 technology for would include 200 MWh of storage systems with a 10-hour energy discharge duration.
According to the companies, this supply agreement allows MN8 to explore opportunities to deploy Eos’ zinc-based Z3 systems throughout its energy portfolio in PJM and other US markets, aiming to deliver LDES that meets the evolving needs of enterprise customers.
The Z3 systems will also use Eos’ DawnOS operating system, which the company says is designed to “maximise the value, reliability, and safety” of its Z3 BESS.
MN8 works in various markets, including commercial and industrial (C&I), grid-scale solar, BESS, and EV charging solutions.
The company states it has approximately 4GW of solar PV projects either operational or under development, along with 1.1GWh of energy storage projects spread across 875 sites in 29 US states.
The barrage of announcements from Eos come as the company prepares to release its Q3 2025 financial results after markets close on 5 November 2025.
