Dominion Energy Carolina Gas Transmission (DECGT) has completed the Charleston Project and it was brought into service on March 1, 2018. This natural gas infrastructure project is 100-percent dedicated to customers in South Carolina, with nearly 94 percent of the capacity serving South Carolina Electric & Gas and its customers. The remaining capacity will serve other businesses across the state. The Charleston Project is the largest expansion project in the history of DECGT, and the third growth project completed since 2015 when Dominion Energy began operations in South Carolina.

Dominion Energy submitted a pre-filing request in July 2015 with the Federal Energy Regulatory Commission (FERC), the agency responsible for reviewing and authorizing interstate natural gas transmission projects. The company received a Certificate of Public Convenience and Necessity in February 2017 from the FERC, which conducted a full review of the project in compliance with two federal statutes, the Natural Gas Act and National Environmental Policy Act.
