Reconciliation Billing Determinants

Monthly | Hourly | Daily

Billing Determinant Definitions

Reconciliation billing determinants are used by PJM to reconcile past months' billings between EDCs and Retail Load Aggregators (a.k.a. Electric Generation Suppliers) for certain allocations that are based on real-time load ratio shares. The reconciliation kWh data supplied to PJM by the EDCs, which represents the difference between the scheduled Retail Load Responsibility InSchedule and the "actual" customer usage based on metered data, are multiplied by the applicable billing determinants to determine the reconciliation billing amounts for each of the following:

Scheduling, System Control & Dispatch Service Charges

PJM Charges - June 2006 - present

Monthly $/MWh rate calculated as PJM's Control Area Administrative Service (Tariff Schedule 9-1) rate, plus PJM's Market Support Service (Tariff Schedule 9-3) rate for transmission customers.

Transmission Owner Charges - July 1999 - present

Monthly $/MWh rate for each zone as filed in Schedule 1A of the PJM Open Access Transmission Tariff.

Regulation Charges

Regulation Charges - August 2005 - present

Hourly $/MWh rates calculated as total cost of Regulation in applicable PJM Mid-Atlantic or Western Control Zone regulation market divided by total real-time load in that market.

Transmission Loss Credits

Transmission Loss Credits – June 2007 - present

Hourly $/MWh rates calculated as total transmission loss revenues divided by total PJM real-time load plus exports.

Synchronized Reserve Charges

Synchronized Reserve Charges - May 2006 - present

Hourly $/MWh rates calculated as total cost of Synchronized Reserve in the applicable reserve zone divided by the total real-time load in that zone.
