Battery maker applies for link to PJM Interconnection
A New Castle-based battery manufacturer said Monday it had applied to PJM Interconnection to bring an energy storage system online onto the regional electrical grid.
Axion Power International Inc. (Nasdaq: AXPW) said its application involved putting a 12.5-megawatt battery system that would store energy similar to Axion’s PowerCube at a former steel plant in Sharon. It would allow Axion to serve the new market of frequency regulation in the energy industry and use Axion’s carbon-led batteries.
“PbC batteries are particularly well-suited to frequency regulation due to their high efficiency at partial state of charge, symmetric charge/discharge profile and long cycle life,” Axion Power Vice President of Engineering Jack Shindle said in a statement Monday.
