Eos Energy Secures $87M DOE Loan Advance to Expand Pennsylvania Battery Production
Event summary
- Eos Energy received an $87M advance from its DOE loan to fund a second production line at its Thorn Hill facility.
- The company has now drawn $178M from the DOE facility since 2024.
- Line 2, which entered commercial production in June 2026, is ramping up to a 2 GWh annual capacity.
- Thorn Hill is expected to support 4 GWh of annual manufacturing capacity once Line 1 is relocated.
- Eos plans to create jobs across 4 shifts to staff Line 2.
The big picture
This DOE-backed expansion underscores the strategic importance of domestic energy storage manufacturing, particularly as grid demands grow. Eos's ability to scale production while managing operational risks will be critical in maintaining its competitive edge in the long-duration energy storage market. The $87M advance reflects the DOE's commitment to supporting U.S.-based clean energy technologies, positioning Eos as a key player in the transition to renewable energy infrastructure.
