PJM's Large Load Registry Closed on 20 October, One of Two Parts of Its Large-Load Filing That FERC Accepted

The registry for new large loads in PJM closed at the end of the day on 20 October. FERC's order of 9 October in ER26-3515 accepted PJM's definition of a large load and the registry, but rejected the other parts of the filing: the IRAS mechanism, the bring-your-own-new-capacity option, and the proposal to exclude certain loads from the demand curve.

PJM's timeline has validation of registry submissions by 14 November, final planning parameters on 19 November, and the base residual auction for 2029/30 opening on 9 December. The preliminary parameters put the forecast peak at 171,916 MW, up 3.6%, and the reliability requirement at 158,712 MW, up 1.7%. The price cap rises to $337.83 per MW-day and the floor to $181.91, from $325 and $175, because the reference resource's capacity accreditation falls from 79% to 76%. Scaling $325 by 79/76 reproduces the new cap.

Valued over a year, by TEI's calculation, the reliability requirement would cost about $19.6 billion at the cap and $10.5 billion at the floor. The parameters also cut the import limit into the ComEd zone by 68% and add PJM West as a newly modelled area.
