PJM last week opened its interconnection queue for new power plant applications for the first time since 2022. PJM has been working through a significant backlog of interconnection requests for the past four years, not allowing any new applications to be submitted while capacity prices have soared and new generation is needed to bring prices back down. PJM hopes that their interconnection queue reform will make projects able to pass through the queue faster than previously. PJM is now estimating it needs a one- to two-year study time for new projects.
The new submissions are made up of natural gas, storage, nuclear, solar, wind, hydro and “other.” The other category consists of biomass, coal, methane, and fusion – which has never been scaled-up to commercial capacities. The new applications add up to approximately 220 GW of nameplate capacity, far more than PJM’s entire current peak load of about 160 MW.
The graphic above offers a breakdown of the technology resources newly submitted to PJM’s interconnection queue. While these projects may move through PJM’s study process in one to two years, approval does not guarantee construction. Projects can still take years to come online, and some may never be built.
The recent history is a reminder of that gap. Since 2020, PJM has processed more than 300 GW of proposed projects, but only 103 GW finalized signed interconnection agreements. Even after PJM approval, projects must still clear permitting, financing, supply chain hurdles and state siting requirements before reaching commercial operation.
PJM now has power plant proposals totaling multiple times its own peak load, but the real test is whether queue reform can turn project interest into actual generation quickly enough to ease historically high capacity prices. 5/4/2026
