What is the difference between the Company load forecast and PJM’s load forecast? What is the MW amount difference per year?
Typically, in the late December timeframe, PJM completes its load forecast for all twenty-two load zones within the PJM footprint and publishes its report on the PJM website. DOM Zone is one of these load zones. Dominion Energy’s load forecasting team utilizes this DOM Zone forecast to derive the load forecast specific to the Dominion Load Serving Entity (DOM LSE). Dominion Energy typically refers to this load forecast as the “PJM-Derived” DOM LSE load forecast. Dominion Energy also develops its own forecast for the DOM LSE. This forecast is usually referred to as Dominion Energy’s load forecast. The PJM-Derived load forecast and the Dominion Energy load forecast are currently being finalized for use in the 2024 IRP. The preliminary results show that the two forecasts are similar to each other throughout the 15-year forecast horizon.
