Transcontinental Gas Pipe Line Company (Transco), a wholly-owned subsidiary of Williams Partners, has received authorization from the Federal Energy Regulatory Commission (FERC) to commence partial service of the Atlantic Sunrise pipeline project.
The FERC ruling, which authorizes operations at modified compressor stations in Maryland, North Carolina and Virginia, adds 150,000 Dth/d of incremental capacity and enables bi-directional flow on Transco’s existing pipeline system.
The Atlantic Sunrise pipeline project includes the following:
- Approximately 183 miles of new greenfield pipe (Central Penn North & Central Penn South)
- Two pipeline loops totaling about 12 miles (Chapman Loop, Unity Loop)
Two and half miles of existing pipeline replacement
- Two new compressor facilities in Pennsylvania
- Other facility additions or modifications in Pennsylvania, Maryland, Virginia, North Carolina, and South Carolina
Once finished, the project will add 1.7 MMDth/d of pipeline capacity to Williams’ Transco system, and is expected to be placed in service later this year.
