Background
Main Line
The East Tennessee Gas Pipeline is operated by Enbridge. A segment of the system extends into southwest Virginia and northern North Carolina through a 95-mile natural gas pipeline that interconnects with the Transcontinental Gas Pipe Line TRANSCO system near Eden, N.C. The East Tennessee Gas Pipeline also interconnects with Texas Eastern Transmission Gas Pipeline, Tennessee Gas Pipeline, Columbia Gulf Transmission Gas Pipeline, Southern Natural Gas Pipeline Company, and Midwestern Gas Transmission Company Gas Pipeline.[1]

Ridgeline Expansion Project
The Ridgeline Expansion Project includes installation of 117 miles of 30-inch pipeline and an additional 8 miles of 24-inch lateral pipeline. This expansion will provide additional transmission capacity to be able to replace coal-fired power generation at Kingston Fossil Plant with gas-fired power generation.
In July 2023, Enbridge applied to build the expansion.[7]
Construction began in 2025.[4]
System Alignment Project
The System Alignment Project involves the abandonment of pipeline facilities in Washington City, VA, and the construction of pipeline facilities and 2 new compressor stations in TN, NC, and VA. The project does not add any new capacity, just improves operational reliability and flexibility. Commencement of service was granted by FERC in July 2025.[5]
