Gas Pipelines Across Virginia

by Staff on June 22, 2014

Recently we wrote about a Spectra Energy proposed gas pipeline that would cross central Virginia north-to-south across Culpeper to Buckingham counties.  If all goes as they plan, it could be operating as soon as 2018.  According to reports from the DOT there are approximately 2,000 miles of these high pressure lines already in VA.   A high-pressure line requires a Compressor station every 40-100 miles in order to boost and maintain its high pressure of as much as 1000 lbs per square inch.  Transcontinental Pipeline (Transco) is an existing high-pressure line, moving gas along lines from the Gulf Coast to NY,  crossing west-to-east through Virginia from WV to Hampton Roads.

But high-pressure lines aren’t the only gas pipelines crossing our state.  Some smaller pipelines pump gas at lower pressures (no compressors required) and those are the branch lines delivering service to households across the state.  DOT reports that 20,000 miles of lower pressure gas lines already cross the state, delivering power to approximately 1.2M Virginians.

There has also been an announcement by Dominion Southeast Reliability Project of a 42-inch 450-mile high-pressure pipeline through Nelson County  from W.VA crossing Virginia to North Carolina.  It would impact Highland to Brunswick counties and has caused concern among Nelson County residents.  If approved, this proposed line would be in service around 2018 although Dominion Resources is still doing feasibility studies on properties.

Another proposed pipeline through southwest Virginia, the Mountain Valley Pipeline (EQT corporation), has 20-year contracts with shipping firms who have agreed to purchase large portions of their potential cubic feet of transmission each day.  It will have a compressor station in Pittsylvania, plans to extend into North Carolina, and should begin delivering gas near the end of 2018.
