What PJM Reported
PJM announced that the bidding window opened June 30 for the capacity auction covering the June 2028 through May 2029 delivery year. The offer window closes July 7, and PJM says results are expected after 4 p.m. Eastern on July 14.
The auction is part of PJM's Reliability Pricing Model, which procures power supply resources ahead of the delivery year. That structure is why capacity results matter to commercial electricity buyers: the clearing price and zone-level outcomes can affect supplier pricing, default service, and pass-through clauses.
Important Caveat
Do not treat this as a result article. PJM has not posted a 2028/2029 clearing price, reserve outcome, zonal spread, or bill impact. Those values should be updated only after PJM publishes official results.
Commercial Buyer Watchlist
| Item | Current Status | Buyer Read |
|---|---|---|
| Clearing price | Not posted yet | No 2028/2029 auction price should be quoted until PJM publishes official results. |
| Capacity pass-through exposure | Review now | Check whether supplier contracts pass capacity through directly, fix it in the energy rate, or reopen pricing after auction results. |
| PLC and peak management | Active risk window | Large commercial and industrial buyers should already be watching coincident-peak behavior before the next delivery year cost reset. |
| Demand response enrollment | Evaluate before results | The auction result will shape capacity economics, but flexible-load revenue depends on account capability, CSP terms, and penalty exposure. |
What To Do Before July 14
- Pull contract language: identify whether capacity is fixed, passed through, reconciled later, or handled in a default-service rider.
- Confirm PLC exposure: capacity charges often connect to peak load contribution. Facilities with flexible demand should know the load-shape math before the result lands.
- Review demand response fit: if your facility can curtail load reliably, evaluate CSP terms, penalties, metering, dispatch rules, and revenue split before treating demand response as found money.
- Prepare a result update: when PJM posts the official clearing price, compare it with prior delivery years and separate RTO-wide facts from zonal outcomes.
What Not To Infer
- No 2028/2029 PJM capacity clearing price is available yet.
- No account-level bill impact can be calculated from the auction schedule alone.
- An auction result will not translate evenly across all PJM customers; tariff class, supplier terms, zone, PLC, and utility riders matter.
