PJM Approves Fourth Project Under Expedited Grid Connection Program

PJM Interconnection on Nov. 10 approved a fourth project under its expedited interconnection process, advancing efforts to bring new generation capacity online as electricity demand increases across its 13-state region. The latest approval covers a 500-megawatt battery storage facility proposed by Little Blue Solar in Beaver County, Pennsylvania, within the Allegheny Electric Cooperative Transmission System zone. The project is expected to enter service in mid-2029.

The approval follows three projects accepted in October, bringing the combined capacity of the four proposals to 2,615 megawatts. These include two battery storage facilities developed by ENGIE IR Holdings, with a combined capacity of 1,660 megawatts, and an upgrade to the existing Hunterstown natural gas facility in Adams County, Pennsylvania, adding 455 megawatts.

PJM opened the application window for its Expedited Interconnection Track on July 31, following federal regulatory approval in June 2026. The temporary initiative is designed to accelerate grid connections for large generation projects capable of entering service within three years, as rising electricity demand, particularly from data centers and other large-load customers, puts pressure on regional supply. The process also gives individual states the ability to prioritize projects based on their resource adequacy needs.

Under the temporary process, PJM can approve up to 10 interconnection requests annually in 2026 and 2027. Eligible projects must provide at least 250 megawatts of unforced capacity, representing the amount of generation capacity credited toward meeting electricity reliability requirements. Applicants must also obtain backing from a relevant state authority willing to help expedite site permitting, a key hurdle for projects seeking to advance toward construction.

PJM expects approved projects to execute generation interconnection agreements within 10 months of submission. Applications are being accepted on a rolling basis until the annual limit is reached. The program is scheduled to expire at the end of 2027.

The expedited process forms part of PJM’s broader response to growing electricity demand and potential supply constraints across its service territory. By accelerating selected storage and generation projects, the grid operator aims to shorten development timelines and bring additional capacity into the system as demand from data centers and other large-load customers increases.
