PJM interconnection queue: capacity, states and timing

PJM's planned pipeline, at 260.3 GW, is 1.1 times the 230 GW of operating capacity that Form EIA-860M lists on the PJM grid. Of the 1,492 planned entries, 1,109 come from the PJM interconnection queue and 383 are planned units from federal generator filings.

Solar accounts for 37% of planned capacity. Natural gas has only 125 entries, but among entries that state a capacity they average 569.6 MW against 109 MW for solar, which brings gas to 71.2 GW. Nuclear has 11 entries at 22.7 GW and battery storage 246 at 38.5 GW. Hydro shows 90 entries but just 385.9 MW, so counts and capacity can point different ways.

Virginia leads with 362 projects and 63 GW, 24.2% of planned PJM capacity. Illinois follows with 50.2 GW and Ohio with 41.5 GW. Pennsylvania has 273 entries, more than Ohio, but 25 GW, well under Ohio's capacity. The eight states shown hold 94.2% of the total.

Of the 1,492 planned PJM projects, 413 carry an expected year earlier than 2026 and 262 carry no date. That is 675 projects, 45.2% of the pipeline and 128.8 GW of capacity, with no usable future date.

Among the dated projects, 2027 is the peak year, with 230 projects and 34.6 GW. The year rows below cover only the dated future entries, so they understate the queue and should not be read as a forecast of what will arrive.

Every one of the five largest entries is above 2.5 GW, and the largest shown is 2.7 GW. Names are shown as the source lists them, and some, such as Salem 500kV and Braidwood 345 kV, read as connection points rather than plant names.

A developer is attributed on 36% of planned PJM projects (537 of 1,492) and 8.2% of operating ones. The other 955 planned rows have no developer attributed in the database, so any developer count for PJM is a floor.

Each PJM row carries its county and status, and the database links attributed developers to the contacts at their companies, so a PJM search can end with a named company and the people there.
