How does the number of in-state RECs required by the VCEA impact modeling?

The renewable portfolio standards of the VCEA are an input into the IRP modeling. The model then selects whether it is most cost-effective 1) to build resources that generate eligible renewable energy credits (RECs); 2) for Dominion Energy to purchase RECs from the market (when available) to meet those requirements; or 3) for the Dominion Energy to incur a deficiency payment as outlined in the VCEA.

Other Stakeholder Questions and Answers

• How are transmission constraints reflected to optimize the generation resources? If there aren’t any transmission constraints modeled, is the location of new generation and new load immaterial as it wouldn’t impact the marginal unit being dispatched?
• What does "with reliability consideration" mean in the context of coal/gas retirements?
