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 (August 28, 2014): Hourly Marginal fuel data were reposted today for January 1, 2013, through June 30, 2014. PJM market participants are not required to report the fuel type associated with each schedule offered into the PJM energy market. The MMU uses publicly available data to determine the fuel type of each unit. For units with multi fuel capability, the MMU has used the primary fuel type to report the share of fuel types used by marginal generators. The MMU has added additional screens to help determine the fuel type used by the units with multi fuel capability. The MMU has reposted marginal fuel data based on these additional screens for the period from January 1, 2013, through June 30, 2014.
