Data

Marginal Fuel Posting

The files below contain data on the fuel types of marginal units in the PJM Real-time Energy Market. Marginal units are the units that set the Locational Marginal Price in each five minute interval. When there is congestion, there can be more than one marginal unit during a five-minute period. The data are at the hourly level. The share of each fuel in each hour is calculated based on the number of five minute intervals that a unit burning each fuel type is marginal or jointly marginal.

Note: Marginal fuel data has been updated and re-posted to include more accurate data regarding fuel types for marginal units, along with more specific fuel categories.
