Every transmission constraint the real-time dispatch was up against, five minutes at a time, with the contingency it bound for and its shadow price (negative, in PJM's convention).

PJM's settled record of every transmission constraint that bound in the real-time market, five minutes at a time, with its contingency, shadow price (negative, in PJM's convention), penalty factor and limit control percentage.

Every transmission constraint that binds in PJM's day-ahead market, hour by hour, with its contingency and shadow price (negative, in PJM's convention), posted with tomorrow's prices.

The dispatch signal PJM sends each of its 20 transmission zones, in $/MWh, every fifteen seconds — the price the control room is steering generators to at the instant, not a settlement price.

What PJM's intermediate-term dispatch expects the next four five-minute intervals to cost at its ties with New York and MISO, re-run every few minutes and kept case by case — the forward-looking price at the seams, MISO's ex-ante counterpart.

Real-time load every five minutes in each of PJM's 21 transmission zones, its three regions and the RTO total — telemetry, the number on PJM's own dashboard, not the metered load that settles.

PJM's settlement-quality hourly load for 30 load areas and the RTO, from the distribution companies' own meters, filled in company by company over the days after — the RTO row is a running total until every company has reported.

PJM's preliminary hourly load for ten areas, integrated from telemetry the day after — between the five-minute reading and the metered settlement load.

PJM's load forecast for the next two hours in five-minute steps, for the zones, the three regions and the RTO, re-issued every five minutes and kept as vintages — so a forecast can be scored against what it said at the time.

PJM's hourly load forecast for the next seven days, for the zones, the three regions and the RTO.

What generated across PJM each hour, by fuel — gas, nuclear, coal, hydro, wind, solar, storage, oil and the rest — with each one's share of the total.

Wind output across the whole of PJM, a SCADA reading every fifteen seconds, kept at that grain.

Metered utility-scale solar output across the whole of PJM every five minutes.

PJM's hourly wind forecast for the next 46 hours, re-issued every ten minutes, and its hourly solar forecast for the next four days — utility-scale and behind-the-meter separately — re-issued hourly.

PJM's wind and solar forecasts for the next six hours in five-minute steps — solar utility-scale and behind-the-meter separately — re-issued every ten minutes.

Actual against scheduled flow every five minutes on each of PJM's ties with its neighbours — New York, the MISO seams, TVA, Duke and the rest — plus the MISO net and the RTO net.

How far PJM is from its interchange schedule and frequency obligation at the instant, in megawatts, every fifteen seconds — the number the control room regulates to zero.

Actual, scheduled and inadvertent flow over each of PJM's ties with its neighbours, hour by hour — the record PJM keeps indefinitely behind the five-minute tie flows it keeps thirty days.

PJM's generation outages for today and the next six days, for the RTO and its two regions, split into planned, maintenance and forced — issued daily and kept as vintages.

PJM's forecast of generation out of service for each of the next ninety days, for the RTO, the west and the rest — issued daily and kept as vintages.

Which five-minute intervals PJM flags as Performance Assessment Intervals — the emergencies in which capacity resources are scored on whether they delivered — for the RTO and the active subzone, as PJM first flags them.

Actual flow against the transfer limit on the eleven interfaces PJM watches for stability — the eastern, central and western reactive interfaces, AP South, Bedington–Black Oak and the seams — every five minutes.

The five-minute regulation clearing price for the PJM RTO, split into its capability and performance components, with the megawatts cleared against the requirement.

Synchronized, primary and thirty-minute reserve every five minutes: the megawatts the dispatch held against each requirement, the clearing price, and whether PJM called the interval short.

PJM's settled real-time results for regulation, synchronized, primary and thirty-minute reserve, every five minutes, for the RTO and the Mid-Atlantic/Dominion subzone: clearing prices, requirements and the megawatts behind them.

PJM's day-ahead results for synchronized, primary and thirty-minute reserve, hourly, for the RTO and the Mid-Atlantic/Dominion subzone: clearing prices, requirements and the megawatts behind them, posted with tomorrow's market.

The megawatts of synchronized, primary and thirty-minute reserve PJM is holding against each requirement, as the control room sees them every fifteen seconds, for the RTO and the Mid-Atlantic/Dominion sub-zone.
