PJM Real-Time Power Market Dashboard

Mild fall weather shaped today’s PJM load profile. Through observed real-time hours, load peaked at 93.7 GW in HE9 as morning demand ramped while temperatures were still cool across major PJM cities, including the low-40s in Washington DC, Philadelphia, Newark, Richmond, Pittsburgh, and Columbus, and near 49°F in Chicago. Afternoon temperatures were generally comfortable, with eastern PJM cities rising into the upper-60s to low-70s, which helped limit weather-driven upside later in the day even as the day-ahead forecast expected the system peak to occur in the evening at 92.8 GW in HE20.

Through HE13, actual load consistently ran above forecast, with misses generally near 0.7-2.3 GW. Real-time pricing averaged materially above day-ahead because of a sharp HE8 event, with average DA LMP at about $56.06/MWh versus average RT LMP at about $78.47/MWh, producing an average DART of -$22.40/MWh.
