Eos Energy Enterprises will relocate its corporate headquarters from Edison to Pittsburgh, a blow to the state’s technology sector that Democrat and Republican administrations alike have tried to support in recent years.
Eos, an innovator in the design, sourcing and manufacturing of American-made zinc-based battery energy storage systems, is investing $352.9 million to relocate its headquarters and expand its existing manufacturing operation in Allegheny County. The state of Pennsylvania is investing $22 million into the project, which is creating at least 735 jobs and retaining 265 current positions.
Eos, founded in 2008, hosts a research and development center and corporate headquarters on 3920 Park Ave. in Edison. Eos develops and manufactures American-made aqueous zinc batteries (Znyth), currently targeting the utility, industrial and commercial sector for power storage.
Eos has leases at two facilities in Turtle Creek in Pennsylvania, where an initial phase of the project began in 2024 with the installation of an automated production line. As part of this expansion, the company will lease an existing 432,000-square-foot facility in Marshall Township in northern Allegheny County where additional production lines are planned for deployment.
Eos will also relocate its corporate headquarters from New Jersey to a 40,000-square-foot office space at Nova Place, located in Pittsburgh’s North Shore neighborhood in the latter half of 2026. This relocation will support Eos’s proprietary battery management system, software, controls, and analytics platform, DawnOS, as well as its corporate operations.
Eos plans to strengthen its partnership with local colleges, notably Carnegie Mellon University, to cultivate a highly skilled workforce proficient in robotics, artificial intelligence, computer science, and engineering.
New Jersey has supported technology companies through strategic investments, tax incentives, infrastructure development and talent cultivation. Programs such as the NJ Angel Investor Tax Credit and Net Operating Loss Program allow tech startups to monetize losses and attract investment.
The state has also created The Edison Innovation Fund that provides direct financial assistance to early-stage tech firms, especially those in life sciences and clean energy.
One possible factor behind Eos’ decision to leave New Jersey is the state’s corporate tax. New Jersey currently has the highest corporate income tax rate in the United States, with a top marginal rate of 11.5% as of 2025, according to the Tax Foundation. Pennsylvania’s corporate net income tax rate is 7.99%, a reduction from 8.49%, part of a multi-year plan to make Pennsylvania more competitive for businesses, according to the website Pa.gov.
