SCC Approval Process

The Virginia State Corporation Commission (SCC) is responsible for verifying the need, determining the route and reviewing the environmental impact of certain transmission lines in Virginia.

The company intends to file its application with the SCC in 2020. Documents related to the case will be available to the public on the SCC Docket Search section of the SCC website in the "Search Cases" section.
