PJM Western Hub peak price hit $563/MWh on 2026-07-09, nearly 9x the 24-hour mean. That is not a summer afternoon spike from a thunderstorm. That is a market signaling that dispatchable capacity is thin and the marginal unit is burning expensive gas at a heat rate that implies delivered fuel costs well above the forward curve.

The mechanism is straightforward: forced outages are eating PJM's cushion. On 2026-07-04 alone, the anomaly log shows five forced outage events totaling over 56,000 MW at the reading level. The largest single reading was 18,267 MW. Maintenance outages added another 3,615 MW across five readings. Those are not planned refueling outages. Those are units tripping or being derated in real time, and PJM's operating reserve margin is not deep enough to absorb them without dispatching the stack's tail. When the last unit in merit clears at $563, the entire hub settles at that price for the hour. The EIA's forecast of 8% lower wholesale prices this summer is an average that masks the tail risk. NEADA's Mark Wolfe is correct: consumers see no savings when the peaks are this sharp.

Watch today for two things. First, the 2026-07-10 forced outage total versus yesterday's. If forced outages remain above 15,000 MW at any single reading, the afternoon peak will test $400 again. Second, watch Dominion South gas. If it ticks above $2.50/MMBtu, the marginal heat rate for the last coal unit in PJM West pushes toward $400 before any scarcity adder. The spread between PJM Western Hub peak and the 5-year average for July 10 is already at a 3-sigma level. If load forecasts for today come in at or above yesterday's actual peak, that spread widens further.

> The $563 print was not a data error. It was the market telling you the reserve margin is a fiction on hot afternoons with units down.
