Generation Projects Totaling 220 Gigawatts Enter PJM Queue Under New Interconnection Framework

PJM Interconnection on April 29 reported that 811 generation projects totaling about 220 gigawatts have applied to connect to its system under the first cycle of a redesigned interconnection process, marking a shift toward faster and more predictable project reviews as electricity demand accelerates.

The application window closed April 27, and the grid operator has begun validating which proposals meet new technical and financial requirements to proceed. All projects in this cycle are being assessed under the updated framework, with prior backlogs fully cleared. The new approach replaces the earlier The reformed process replaces PJM’s prior first-come, first-served model with a first-ready, first-served approach that prioritizes projects demonstrating site control, financial commitment, and overall viability before entering the queue. The changes aim to limit speculative proposals and improve completion rates.

The intake reflects a broad mix of resources. Energy storage leads the cycle in project volume with 349 individual applications representing 66.5 GW. However, natural gas represents the largest share of total nameplate capacity at 105.8 GW. Combined, these two resource types, along with solar, which adds 14.8 GW, account for approximately 85 percent of the total capacity in the new queue. The remaining portfolio includes smaller contributions from wind, nuclear, and hydro, as well as emerging technologies like fusion. Despite the sizable pipeline, historical trends suggest only a portion of projects will ultimately reach commercial operation.

To handle the volume, the operator is deploying new digital tools, including an artificial intelligence-enabled platform developed by Google unit Tapestry. The system supports document review and data screening, with the potential to shorten study timelines. The operator plans to assess the tool’s performance throughout the first cycle.

Rising electricity demand across the region, driven by data centers, industrial expansion, and broader electrification, underpins the surge in project applications. The operator expects load to increase by more than 30-gigawatts through 2030, raising concerns about reliability if new supply does not come online in time.

Since 2020, the operator has processed more than 300-gigawatts of projects, though many face delays tied to permitting and supply chains. The new process, expected to take one to two years per cycle, is designed to better align project development with system needs while ensuring reliable service across its multi-state footprint.
