Power · the capacity price on the bill
$329.17 a megawatt-day clears PJM’s capacity auction, up from $28.92
The price is what PJM’s auction pays for capacity, a promise to supply power at the peak. Utilities and suppliers pay it for their customers’ share of the peak, and pass it on in their rates. Each figure cites PJM’s own report; retrieved 16 October 2026.

Your peak load contribution is your share of your zone’s summer peak, and your utility sets it once a year. Some bills and most supplier contracts print it as a PLC, a capacity obligation or a peak load contribution. PJM priced some zones apart from the rest in 2024/25 and 2025/26, and every zone alike in 2026/27, 2027/28 and 2028/29. Dominion’s zone supplied its own capacity in 2024/25: “Dominion FRR has changed to RPM and therefore the entire Dominion zone is now in RPM.” (2025/2026 Base Residual Auction Report, p. 7).
PJM’s load forecast grows 15,314 MW over four auctions
what each auction bought for, and what it cost| Delivery year | Load forecast | Short of the requirement | Cleared MW × price | As a bar |
|---|---|---|---|---|
| 2024/25Jun 2024 – May 2025 | — | — | $2.2 bn | |
| 2025/26Jun 2025 – May 2026 | +3,243 MW | — | $14.7 bn | |
| 2026/27Jun 2026 – May 2027 | +5,446.1 MW | — | $16.1 bn | |
| 2027/28Jun 2027 – May 2028 | +5,249.9 MW | 6,516.6 MW | $16.4 bn | |
| 2028/29Jun 2028 – May 2029 | +1,374.5 MW | 6,831.3 MW | $16.4 bn |
Cleared megawatts times price: $16.1 bn for 2026/27, from $2.2 bn for 2024/25. “Note that the $16.4 billion value does not equate to a total cost to load because load that is hedged through self-supply or bilateral contracts is not exposed to the clearing prices in the auction.” (PJM, p. 7.) The reports for 2027/28 and 2028/29 give the forecast’s rise as “largely due to additional Large Loads”. The Buildout tracks the largest AI data centers.
