Eos Energy and Talen Energy partner to power AI infrastructure in Pennsylvania

Trump’s $92 billion plan to transform Pennsylvania into a national AI data center hub is supposed to create thousands of jobs make the state better off.
But the initiative is also raising alarms about the strain it could place on the region’s already stressed power grid.
“When you're talking about putting a 1,000-megawatt or 2,000-megawatt load onto the grid, that is a massive load for a single geographic location,” said Dr. Benjamin Lee, a University of Pennsylvania professor of electrical and systems engineering.
“That is going to pose a risk to the electrical grid.”
Overseen by a nonprofit organization called PJM, it is the nation's largest power grid and services 13 other states besides Pennsylvania, as well as the District of Columbia.
And during the same week that Trump announced the multi-billion-dollar AI data center hub plan, a bipartisan group of governors from 10 of those states sent a letter to PJM demanding larger oversight of the grid because of skyrocketing electricity costs to customers.
Which means that as the US pours investments into building this AI hub, the biggest question remains how will it power all these data centers.
As part of Trump’s plan, several energy, tech and finance firms, including Constellation Energy (CEG), Alphabet’s Google (GOOG), GE Vernova (GEV) and Blackstone (BX), announced funding initiatives to help expand power services in the region.
And on Tuesday, Eos Energy Enterprises (EOSE) and Talen Energy Corporation (TLN) said that they have formed a strategic collaboration to increase energy storage capacity across Pennsylvania in order to support the growing demand for power that AI infrastructure is causing in the state.
An urgent need for power creates opportunity
The two companies will be integrating Eos’ Z3 battery technology with Talen’s vast generation portfolio in Pennsylvania to both deliver reliable and cost-effective power, while also helping the state transition to clean energy.
They noted that the proliferation of AI and cloud computing has created a situation where the “urgency to bridge power deficiency has never been greater.”
As part of the agreement Eos and Talen will jointly identify multiple storage projects across Talen’s portfolio that they can develop.
This will include locations that are at or near operating Talen sites in Pennsylvania — as well as retired fossil fuel plants that can be brought online again.
“Our collaboration with Talen marks a significant milestone for Eos and the broader Pennsylvania energy ecosystem,” Eos Energy CEO Joe Mastrangelo said in a statement.
“By pairing Talen’s operational expertise and infrastructure with Eos’ safe, scalable zinc-based storage technology, we’re demonstrating how American innovation can strengthen grid resiliency, address a national security imperative, and power the next generation of digital infrastructure with urgency.”
Mac McFarland, president and CEO of Talen Energy, said that the partnership gives them “the potential to optimize and increase generation capacity and deploy durable, long-duration storage — made and located right here in Pennsylvania — to support data centers and communities with reliable, low-carbon energy.”
Eos Energy’s stock gained 8.6% on Tuesday, while Talen’s stock fell 6.1%.
Stifel analysts, led by Stephen Gengaro, reiterated their Buy rating on Eos and maintained a $22 price target. Gengaro cited “contract wins, capacity growth, and Al-driven demand underpinning bullish stance.”
While he awaits further details about the partnership with Talen, Gengaro expects it to be “a significant plus for EOSE."
