How the measured and official figures differ
Measured values (preliminary)
This app pulls PJM's hourly metered load (Data Miner feed hrl_load_metered) each morning
and ranks the five highest June–September days for each zone. These are preliminary values: PJM
revises metered load during settlement, so measured figures can change after they are first published
and can differ from PJM's final numbers.
PJM official 5CP
After each summer, PJM publishes its Summer Peaks and 5CPs report (typically October–November, with later revisions noted in the report). The official 5CP are the five highest RTO daily peak hours in June–September, using final, unrestricted load: metered load with load reductions from demand response and similar programs added back. Because of settlement revisions and the unrestricted adjustment, official MW values usually differ from measured values, and occasionally a different day qualifies.
ComEd load during the RTO 5CP hours
PJM's report also lists each zone's load during the five RTO peak hours (page 2, Coincident Peaks, By Zone). The ComEd figures shown under each season come from that table. This coincident load is what determines ComEd customers' share of RTO capacity and transmission costs. It is not the same as ComEd's own highest days, which can fall on other dates and are shown separately below it.
Weather-normalized peaks
PJM adjusts each season's peak loads to normal weather and reports one weather-normalized peak for the RTO and each zone. PJM uses the weather-normalized zonal peak in setting each zone's capacity obligation for the delivery year that begins the following June; utilities then allocate that obligation to individual customers based on their load during the 5CP hours. The weather-normalized peak is a single adjusted value per zone, not a measured hour, so it has no date or time.
Hours
PJM reports hours as hour ending, Eastern Prevailing Time. This page shows hour beginning, Central Prevailing Time, so PJM's hour ending 18:00 EPT appears here as 4:00 PM CPT.
