Other Stakeholder Questions and Answers

How has Dominion Energy evaluated and/or included advanced transmission technologies (ATTs) or dynamic line rating (DLR) deployments in the PJM RTEP process?
Given difficulties permitting new transmission lines, shouldn't new nuclear come with some locational constraints, such as co-location with Data Centers?
