Virginia Southside Expansion Project II

Williams is pursuing an expansion of its Transco interstate natural gas pipeline to provide additional service to markets in southern Virginia during the fourth quarter of 2017.



Dominion Virginia Power needs additional natural gas pipeline capacity to fuel a new 1,580-megawatt, combined-cycle, natural gas-fired electric generation facility that it plans to build in Greensville County, Virginia. The Transco pipeline currently operates a 20-inch pipeline and is in the process of constructing another 24-inch diameter pipeline in southern Virginia which would need to be expanded to provide the 250,000 dekatherms per day of natural gas required to serve the new power station.

Compression Facilities

The proposal includes unit additional at compressor facility station in Pittsylvania County, Va. This facility would be powered by natural gas turbines operating at 15,400 horsepower. In addition, there would be an additional electric motor added to an existing Transco compressor station in Prince William County, Va.

Meter Stations

The proposal also includes plans for one delivery metering and regulator station in Greensville County, Va.

Pipeline Addition

The proposal consists of approximately 4 miles of new 24-inch diameter pipeline extending from the Transco Brunswick Lateral in Brunswick County, Va., and terminating in Greensville County, Va. The pipe would be placed alongside of the existing utility corridor.

Regulatory Process

Interstate natural gas pipelines are regulated by the Federal Energy Regulatory Commission (FERC). As such, FERC requires pipeline operators to obtain a federal Certificate of Public Convenience and Necessity, in addition to various state permits, before any pipeline facilities can be built.

Williams submitted an application with the FERC for the Virginia Southside II project on March 23, 2015. The project was assigned Docket Number CP15-118. The project was approved by FERC in July 2016.

All documents and correspondence submitted to or issued by either the company or FERC regarding the proposed project can be accessed by referencing the project docket number (CP15-118) on the FERC website.

Proposed Schedule

  • March 2015 – FERC Filing
  • October 2016 – Compressor Station construction starts
  • January 2017 – Pipeline Construction Starts
  • Fourth Quarter 2017 – Proposed In-Service
