Generation by Fuel Type

PJM's hourly operating generation snapshot broken out by fuel type — gas, nuclear, coal, solar, wind, hydro, storage, and others.

Overview

This is the current metered fuel-mix signal for the RTO and the appropriate live actual for PJM's renewable forecasts; the settlement-derived wind and solar tables lag and can carry provisional zeros at the operational edge. Source: PJM Market Data.

Query contract

Preserve one canonical row per (event_time, fuel_type) before aggregating.

Analysis rules

  • Group only after preserving the declared grain: event_time, fuel_type.

Access

Query from your own tools

Use the guarded HTTP endpoint directly, or connect an MCP client and load the dataset contract with describe_data before calling query_data.
