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?

The IRP modeling is not location-specific and only accounts for generic resources to meet demand within the Dominion Load Serving Entity territory.  Thus, transmission constraints are not a specific input reflected in the IRP model.  

Other Stakeholder Questions and Answers

• Technology cost is important but does not seem to be reflected here, nor is it clear what candidate resources are provided for the model to pick. What additional technology is being considering in the model, e.g. CCS, long duration storage, etc.?
• Is there regional planning occurring for demand, specifically around data centers?
