FERC okays gas pipeline project to supply Greensville power plant in Va.

On July 7, the members of the Federal Energy Regulatory Commission approved a March 2015 application from Transcontinental Gas Pipe Line Co. LLC (Transco) for a certificate of public convenience and necessity to construct and operate the Virginia Southside Expansion Project II (VSEP II).

This project is intended to provide 250,000 dekatherms per day (Dth/day) of incremental firm transportation service for Virginia Power Services Energy Corporation Inc. (Virginia Power).

Transco plans to construct and operate the proposed project to provide 250,000 Dth/day of incremental firm transportation service to a delivery point at the end of its proposed 4.9-mile-long Greensville Lateral to serve Virginia Electric and Power‘s 1,588-MW Greensville County plant in Virginia. Virginia Power and Virginia Electric and Power are both units of Dominion Resources (NYSE: D). The Greensville County power plant has just gone into construction.

The 250,000 Dth/day of firm service would include 165,000 Dth of service from Transco’s Zone 6 Station 210 Pooling Point on Transco’s mainline in Mercer County, New Jersey, and 85,000 Dth of service from its Zone 5 Station 165 Pooling Point in Pittsylvania County, Virginia.

Transco plans the construction and operation of the following new facilities and modifications to existing facilities:

  • the Greensville Lateral, consisting of approximately 4.19 miles of 24-inch-diameter pipeline extending from milepost 5.2 on Transco’s existing Brunswick Lateral in Brunswick County, Virginia, to VEPCO’s proposed power plant in Greensville County, Virginia;
  • one 25,000 horsepower (hp) electric-driven compressor unit at Transco’s existing Compressor Station 185 in Prince William County, Virginia;
  • two 10,915 hp gas-driven compressor units, three bays of cooling equipment, and the re-wheeling of two existing compressor units at Transco’s existing Compressor Station 166 in Pittsylvania County, Virginia;
  • a new delivery meter station and gas heaters at the terminus of the Greenville Lateral at VEPCO’s Greensville power plant;
  • modifications to odorization/deodorization facilities at Transco’s Compressor Station 140 in Spartanburg County, South Carolina, and to valve settings and meter stations between Compressor Station 140 and Transco’s Tryon Lateral and on Transco’s mainline in North Carolina and South Carolina; and
  • various related appurtenances underground facilities and aboveground facilities such as valves and valve operators, launchers, and receivers.

Transco estimates that the project will cost approximately $190.8 million.

The precedent agreement with Virginia Power is for firm transportation service under Transco’s Rate Schedule FT for an initial 20-year term.
