Read PJM nodal prices and operating conditions
PJM publishes prices at individual pricing nodes, hubs and zones. The five-minute real-time feed and the hourly real-time series have different publication schedules. Hub history on Ask the Grid uses the hourly series, published about a day after delivery; the price map uses the five-minute feed.
Compare demand, fuel mix and published transmission constraints at matching times when investigating price differences. PJM also publishes interconnection requests and operating notices, which describe different stages of grid development and operations.
Open the price map to explore a location, the queue map to investigate project requests, or Radar to monitor the market. Questions opened from this page carry PJM as their market context.
