Virginia regulators seeks comments on Dominion’s Dahlgren transmission line

The Virginia State Corporation Commission on Feb. 16 filed its procedural order for Virginia Electric and Power Co. d/b/a Dominion Virginia Power‘s proposed Dahlgren Transmission Line Project to be built in King George County, Va.

The commission’s order, among other things, includes a public hearing scheduled for June 12, 2012. The hearing will be held in Richmond, Va.

Dominion Virginia Power has proposed to construct and operate a new 230 kV overhead double-circuit transmission line, which would terminate at the new 230-34.5 kV Dahlgren substation.

The company plans to tap the existing 230 kV Birchwood-Northern Neck Line to loop in and out of the proposed Dahlgren substation, which will be located on Naval Support Facility.

The proposed route would run for about 9.43 miles, and the alternate route would run for about 9.67 miles. The proposed or alternative route would originate at a point on the Birchwood-Northern Neck Line and terminate at the proposed substation.

The transmission project is necessary to meet projected load growth in the Dahlgren area, including commercial load growth and growth at NSF Dahlgren. Load projections show that the two existing distribution circuits in the Dahlgren area will overload if the proposed new facilities are not in service by May 2014, according to the company’s filing.

The estimated total cost of the proposed project is about $36.4 million, which comprises about $28.2 million for the line construction, and about $8.2 million for the estimated cost of substation work.

On or before June 5, written comments on the application may be submitted. Comments also may be submitted electronically at scc.virginia.gov/case, according to the commission.

Dominion Virginia Power is a subsidiary of Dominion Resources (NYSE:D).
