Texas company Talen Energy Corporation has unveiled plans to develop 1GW of stand-alone battery storage projects as part of its strategic transformation to a renewable energy and digital infrastructure growth platform.
The projects, which range from 20MW to approximately 300MW across three states, are expected to be developed over the next three to five years using Talen-owned land and legacy fossil generation and transmission infrastructure.
Talen said the first two developments are 20MW demonstration projects adjacent to its HA Wagner and Camden generation facilities in Maryland and New Jersey, respectively.
The HA Wagner facility is among the coal-fired facilities that Talen announced will cease burning coal by the end of 2025.
The Camden battery project is expected to serve as an added capacity resource adjacent to the company’s natural gas generation facility.
The company expects to start construction of the demonstration projects in the fourth quarter of this year.
Talen president Alex Hernandez said: “Talen’s battery storage development projects will play a key role in advancing our country’s clean energy transition.
“The batteries of the 1960s, also known as fossil power plants, will ultimately be converted to the batteries of tomorrow, which we believe will include battery packs utilising various technologies.
“These battery projects, together with Talen’s existing zero carbon nuclear baseload generation, are intended to serve as a backstop for renewables’ intermittency, ensuring that power is available when needed.
“We believe our Giga-scale battery development pipeline will become increasingly valuable as battery technology improves and manufacturing costs decline with scale deployments.”
