Dominion Energy Transmission, Inc., headquartered in Richmond, VA, is the interstate gas transmission subsidiary of Dominion Energy. The company is primarily a provider of gas transportation and storage services. We operate one of the largest underground natural gas storage systems in the United States, with links to other major pipelines and to markets in the Midwest, Mid-Atlantic and Northeast regions.

We maintain more than 3,900 miles of pipeline in six states: Ohio, West Virginia, Pennsylvania, New York, Maryland and Virginia. We store and transport large quantities of natural gas for large customers, such as major utilities and power plants. Dominion Energy Transmission also is a producer and supplier of natural gas liquids at facilities in West Virginia and Maryland.

By making enhancements to our existing facilities, we are giving large customers more options in moving gas into their markets. We also are implementing innovative new ways to serve customers with products and services that go beyond the traditional.
