"Eos moved into a shuttered Westinghouse plant, revitalized it, and is now producing some of the most advanced batteries in the world to meet rising energy demand.” — @AlexFitzDC
We're grateful to @ZitoSalena for highlighting the recent visit by U.S. DOE Associate Deputy Secretary, Alex Fitzsimmons, to our Western Pennsylvania facilities.
Her article explores how Eos is transforming a historic manufacturing site into a hub for advanced battery production and American energy innovation.

WARRENDALE, Pennsylvania — Joe Mastrangelo stood on the mezzanine overlooking the factory floor of Eos Energy Enterprises’ new plant, his eyes welling as he looked out over the rows of yellow-caged robotic cells, conveyors, and steel gantries stretching nearly the length of the building below.
“I come and stand here every morning, and I still can’t believe that this is where we are today,” the Eos CEO said. “I am both so humbled and also proud of what we are building.”

25 years ago, America was attacked—but we were not broken.
We remember the nearly 3,000 lives lost, the families forever changed, and the first responders and everyday Americans who showed extraordinary courage in the face of evil. What followed was a powerful reminder of who we are as a nation: resilient, united, and determined to stand together when it matters most.
We honor their memory today and always. We will never forget.
