US Stock Market Move | Eos Energy (EOSE.US) rose nearly 18% in pre-market trading, reaching an agreement to supply power to a data center in Pennsylvania.

As of the time of writing, the stock price of battery manufacturer Eos Energy (EOSE.US) rose by 18.05% in pre-market trading on Tuesday. The company announced plans to invest in building a $75 million factory, which is expected to help Talen Energy (TLN.US) provide power support for the growing data centers in Pennsylvania. Eos Energy CEO Joe Mastrangelo stated that Eos is building a factory capable of producing 2 GWh of batteries after partnering with Talen. The factory is set to start operations in mid-2026, doubling the energy storage production capacity in the Pittsburgh area. The energy produced can meet the electricity needs of about 1.5 million households for an hour. Batteries are crucial for providing power support to the grid and maintaining grid stability, especially as the generation from CECEP Solar Energy and wind power can fluctuate. These devices are typically charged during low demand and discharged during high demand, allowing coal and natural gas power plants to operate more stably. Mastrangelo mentioned that the factory is expected to help Talen utilize its generation resources more efficiently, including its Susquehanna nuclear power plant and fossil fuel power facilities, partly to serve Amazon.com, Inc.'s data centers in the area. Eos already has a similar facility nearby and plans to eventually increase its generation capacity to 8 GWh. Additionally, Eos will receive $24 million in grant funds from Pennsylvania to expand its business.
