Overview

PJM system generation broken out by fuel type every five minutes — gas, nuclear, coal, solar, wind, hydro, storage, and others — with each fuel's output in MW, its share of the total, and a renewable flag. This is the live fuel-mix signal for the PJM footprint: read it for current renewable output, the marginal fuel, and how the mix shifts across the day. Source: PJM Data Miner 2.

This table is readable two ways, over the same guarded boundary. Over HTTP: POST /api/v1/datasets/pjm_gen_by_fuel/query, described in the API reference. Or from an MCP client: connect a market below, then use search_data or describe_data to load its query contract before calling query_data.

7-Day Load ForecastPJM's seven-day-ahead hourly load forecast by forecast area, refreshed through the day. Rows are keyed by target time (event_time) with the issue time in evaluated_at_utc; take the latest vintage per target hour via an argMax over evaluated_at_utc. Forecast areas match the very-short-term feed (utility names, RTO_COMBINED for the system total). This is the table for tomorrow's peak and the week-ahead demand outlook. Source: PJM Data Miner 2.Day-Ahead Hourly LMPCleared day-ahead locational marginal prices for each PJM pricing node by delivery hour, with total LMP and its system-energy, congestion, and marginal-loss components in dollars per MWh. The table supports the posted next-day hourly curve, day-ahead-to-real-time basis, and node-level component attribution. A congestion component does not by itself identify which facility is expected to bind or establish a node-to-constraint relationship. Source: PJM Data Miner 2.Day-Ahead Transmission ConstraintsThe transmission constraints that bound in PJM's day-ahead market: the monitored facility, the contingency facility, the duration, and the congestion event. It names which elements are expected to limit flows for the next operating day. Note that PJM does not publish a real-time binding-constraint/shadow-price feed, so real-time congestion is read from the congestion component of the LMP tables rather than from a constraints table. Source: PJM Data Miner 2.Generation Outages by TypePJM's daily generator-outage outlook by report date, target forecast date, and region. Each row separates total, planned, maintenance, and forced outage capacity in MW for PJM RTO, Western, or Mid Atlantic - Dominion. This is generation availability evidence from PJM Data Miner 2, not distribution-customer outage data. Source: PJM Data Miner 2.
