Eos Energy Enterprises, a maker of zinc-based battery energy storage systems, will move its headquarters from Edison, N.J., to Pittsburgh and expand production in Allegheny County in a $352.9 million investment that state officials are calling a cornerstone of Pennsylvania’s clean energy manufacturing push.
The project, announced Oct. 21 by Gov. Josh Shapiro (D) and the Pennsylvania Department of Community and Economic Development (DCED), will create at least 735 new jobs and retain 265 existing jobs, for a total of about 1,000 jobs.
The commonwealth said it has committed $22 million in incentives for the move: a $10 million Pennsylvania First grant, $12 million from the Redevelopment Assistance Capital Program, including $3 million awarded in 2022, and Allegheny County’s $2 million contribution from its economic development fund.
“The demand for energy is increasing, and Pennsylvania is doubling down on its strengths as a national energy leader and clean exporter,” Shapiro said in a statement. “We’re competing for and winning important projects like this by cutting red tape, growing our skilled workforce and investing in the next generation of energy technology.”
Eos said it will lease a 432,000-square-foot industrial facility in northern suburban Pittsburgh to add new automated production lines for its zinc-aqueous battery systems. The company currently leases two smaller facilities nearby, where a first phase of expansion began in 2024.

Founded in 2008, Eos manufactures stationary energy storage systems using its proprietary Znyth technology, commercialized for utility-scale industrial and commercial applications. The company reports that approximately 91% of its component content is domestically sourced.

The expansion, known internally as Project AMAZE, is designed to increase manufacturing throughput, lower costs per kilowatt-hour and strengthen the company’s U.S. supply chain.
“Through Project AMAZE, we’re showing that you can make things in America again by combining advanced manufacturing with innovative software,” said CEO Joe Mastrangelo, adding that the company is “doing it right here in Pennsylvania to build a more efficient and secure energy future.”
The corporate headquarters will move in late 2026 to a 40,000-square-foot space at Nova Place, a redeveloped complex on Pittsburgh’s North Shore. Eos said the office will house its software, analytics and controls teams that develop the company’s DawnOS battery management platform.
Rick Siger, DCED secretary, said the project “will create and sustain 1,000 jobs while expanding opportunities for the people of western Pennsylvania.”
He credited the layered structure of the incentive package — grants, capital assistance and possible tax credits — for making the relocation financially feasible.
Renovation of plants and perspective of the project
Marshall Township construction will require new process equipment bases, electrical distribution systems, high-capacity HVAC, material handling infrastructure and integration of factory automation with Eos’ proprietary software stack.

Local officials said they expect the tenant facility to appear in city planning files by the end of the year, with bid packages expected in early 2026. The company has not yet identified its architect or construction manager.
Stefani Pashman, CEO of the Allegheny Conference on Community Development, said the Eos decision affirms “the value proposition this region offers at the nexus of energy, manufacturing and innovation.” He added that the move will “strengthen our region’s position as a center for advanced energy storage and attract new suppliers, partners and innovators.”
The expansion of Eos is based on an ongoing federal partnership. In December 2024, the US Department of Energy’s Office of Loan Programs closed a $303.5 million loan guarantee under its Title 17 Clean Energy Financing Program to fund Project AMAZE, supporting the scale-up of Eos to 8 GWh of annual battery system production capacity.
DOE officials said the deal represented “a model for domestic battery manufacturing with non-toxic, non-lithium chemistry,” and the project aligns with other clean-tech manufacturing announcements in the Pittsburgh region.
Mitsubishi Electric Power Products recently opened a $92.7 million manufacturing and testing facility north of the city, while Mainspring Energy plans a 300,000 square meter clean technology plant backed by $8.6 million in state funding. Together they mark what economic development officials describe as a wave of reindustrialization focused on electrification, automation and energy storage.
With its layered public funding package, Pennsylvania officials say the Eos project will help re-establish Pittsburgh as a growing hub in the U.S. battery manufacturing network, giving the steel city’s long-evolving industrial base another chance to build what it once supplied: the hardware of modern energy.
