About Dominion Carolina Gas Transmission

Who We Are

Dominion Carolina Gas Transmission is an interstate natural gas transportation company that delivers natural gas to wholesale and direct industrial customers throughout South Carolina. Our operations and rates are subject to Federal Energy Regulatory Commission (FERC) regulation.

We provide open access, unbundled, firm and interruptible transportation services and interruptible parking and lending service for interstate gas markets. Because we sell our "pipeline capacity" rather than natural gas itself, we enable large-volume natural gas users to manage their own purchasing strategies.


Effective February 1, 2015, Dominion Resources, Inc. acquired Carolina Gas Transmission Corporation (CGT) from SCANA Corp. On March 24, CGT assumed its new name as Dominion Carolina Gas Transmission, LLC, and on April 1, 2015, Dominion Midstream Partners, LP, acquired Dominion Carolina Gas Transmission from Dominion Resources, Inc.

CGT was originally formed through the 2006 merger of two of SCANA Corporation's wholly owned subsidiaries: SCG Pipeline and South Carolina Pipeline Corporation.

South Carolina Pipeline was an intrastate pipeline company that purchased, transported and sold natural gas to distribution companies, municipalities and industrial customers through an extensive pipeline system in South Carolina. SCG Pipeline was an interstate pipeline that transported natural gas in Georgia and South Carolina.

Having leveraged the strengths and resources of these two companies, Dominion Carolina Gas Transmission today transports reliable natural gas throughout the growing southeast region of the United States.
