Eos Energy Enterprises has apparently abandoned plans to construct a manufacturing facility in Duquesne — but no one bothered to tell city officials.

In 2024, New Jersey-based Eos Energy Enterprises, which operates a factory in Turtle Creek, received planning approval from Duquesne officials for a 181,000-square-foot facility on the site of the former U.S. Steel Duquesne Plant that would have employed 300 to 400 people.

But since then, the company has gone quiet, even after Pennsylvania Gov. Josh Shapiro announced that Eos plans to relocate its corporate headquarters to Pittsburgh’s North Side and open its new manufacturing facility in Marshall Twp. in northern Allegheny County instead.

“All of us — the city, our city manager, all the council members, the planning commission, zoning board — nobody had any idea,” said Duquesne City Councilman Aaron Adams. “We were caught off-guard (when) the announcement came out from the state and county.”

Eos Energy Enterprises officials did not return messages from Tube City Almanac seeking comment.

Last week, Eos Energy and state and county officials announced the company will relocate its corporate headquarters to the former Allegheny Center Mall in Pittsburgh and lease a new 432,000 square foot facility in Marshall Twp., 30 miles north of Duquesne.

The county and state will provide $24 million in economic development funding. The total investment is valued by Eos at $353 million.

Eos Energy produces industrial-scale batteries that can store large amounts of energy for extended periods of time — anywhere from four to 16 hours or more. The battery technology is considered crucial to data-processing centers and for making alternative, green forms of energy, such as solar and wind, practical.

Eos first entered the Pittsburgh market in 2019 at the former Westinghouse plant in Turtle Creek. CEO Joe Mastrangelo, Shapiro and others had compared the job creation potential of its zinc-halide batteries to the steel that was formerly made in the Mon Valley communities.

When Duquesne approved Eos’s plans in 2024, the company predicted it would be breaking ground in early 2025. City officials said they were excited about the possibility that restaurants and other business opportunities would follow the Eos investment.

The proposed facility on South Linden Avenue would have included three parcels of land near the Monongahela River, but shovels never went into the ground.

The Eos deal was contingent on receipt of a $303.5 million federal loan approved by the U.S. Department of Energy in December 2024 during the Biden Administration. Since President Trump took office, the federal government has shifted away from so-called “green energy” projects in favor of new investments in coal- and gas-fired power plants.

Adams said city officials were aware that federal support for Eos might be in jeopardy after Biden left office.

Adams said Duquesne officials are “saddened” that no one from Eos, the state or county told them the previously approved plans — to grow the Turtle Creek facility and add a factory in Duquesne — had been scrapped.

“None of that was brought to our attention,” he said.

For a community that has recently emerged from Act 47 financial oversight and which is planning to transition to a new Home Rule Charter, the new jobs were considered a lifeline, Adams said. He said a significant investment in Duquesne would have benefited communities throughout the Mon Valley. 

But Duquesne officials never heard any reports from the state or county that Eos was looking at other communities, Adams said, adding that the city feels betrayed.

He and others in Duquesne said they can’t understand why the company, its engineers, or county or state officials didn’t give them a “heads up” that the plan was abandoned.

City officials will work to market the proposed Eos site to other businesses instead, Adams said.

Duquesne “is overlooked time and again,” he said. “We just got to buckle down and do it on our own as a community.”
