Three signals PJM bulls are overlooking as the queue delivers
The consensus is pricing structural deficit. The infrastructure pipeline and regulatory risk tell a different real-time story.
PJM Western Hub spot power settled at $72.38/MWh at Tuesday's close (2026-07-21), a fraction of the price-cap levels that dominated the summer narrative [live_prices]. The heat dome that pushed the grid to 163 GW on Thursday (2026-07-02) has passed, but the demand-at-any-cost story lingers. Traders and analysts remain focused on data centres clearing capacity auctions at the cap and regulators scrambling to respond5. That consensus is real. It is also worth testing against the supply-side evidence.
Over 55 GW of new generation has cleared PJM’s interconnection queue and is ready to build, according to the Electric Power Supply Association3. Another 220 GW entered the latest review cycle. When PJM asked developers whether they would contract directly with large loads, 130 GW came forward3. The queue is not evidence of gridlock; it is a pipeline that could deliver before the data centres have fully connected.
History cautions against assuming those volumes materialise. Only 13% of the capacity that submitted interconnection requests from 2000 to 2019 had reached commercial operations by the end of 2024; 77% had been withdrawn1. Developers pile into queues to secure optionality, then reassess as timelines slip, costs climb or offtake terms change. The 130 GW that volunteered to contract directly with large loads shows supply is willing to chase demand, but it also shows developers hedging against PJM’s capacity construct being reformed away from them.
Jefferies equity analysts said exactly that on Wednesday (2026-07-15). They wrote that they “continue to expect long-term structural reforms in the base residual auction toward a continuing operating cost model with materially lower prices”4. If capacity prices fall, the entire revenue stack for new-build generation shifts. Some of the 55 GW that cleared the queue will not pencil out, and the scarcity premium embedded in real-time prices will evaporate.
The real-time market has already started to decouple from the capacity narrative. July’s heat event pushed hub prices but did not break the grid. PJM forecast load could top 166,000 MW for Thursday (2026-07-02); actual load came in at roughly 163 GW, below the 2006 all-time record of 165,563 MW2. The system held. Marginal pricing eased as the heat wave broke, and real-time prices collapsed back toward the mean.
The fleet is larger than the squeeze narrative suggests. Competitive power suppliers alone own and operate more than 225,000 MW of capacity across PJM’s footprint3. The retirement wave that everyone feared has been slowed by reliability-must-run agreements, state subsidies and FERC’s reluctance to let baseload units close.
The catalyst to watch is a reform announcement out of PJM or FERC. If the base residual auction gets restructured toward lower, more predictable pricing, the equity and credit markets will reprice the entire build-out thesis. The real-time curve would shift lower as the scarcity premium fades. If instead the queue continues to clear and build, the physical overhang grows before the data centres have plugged in.
For now, the market is pricing a structural power deficit that drives capacity prices to the cap. The risk it is missing is that the infrastructure pipeline delivers, the regulatory floor falls out and real-time pricing normalises before the demand wave fully arrives.
