The only transmission project completed in May 2012 was Dominion Resources‘ (NYSE:D) 230-kV Remington to Gainesville project in Virginia.
The project connects the company’s Remington combustion turbine facility in Fauquier county to the Gainesville substation in Prince William county.
The project represents a total of 25 miles of line completed in May. In May 2011, 356.3 line miles were completed, comprising 104.5 miles of 230-kV line, 82 miles of 345-kV line and 169.8 miles of 500-kV line.
As of the end of May, the United States has seen 343.2 miles of lines completed so far in 2012; on an annualized basis, about 824 line miles can be expected to enter service in 2012, less than half of the 1,775.4 miles that entered service in the January to December period last year.
Of the 343.2 line miles, 63.6 miles were 230-kV, 200.6 miles were 345-kV and 79 miles were 500-kV. Of the 1,775.5 miles completed in 2011, 1,018.5 miles were 230-kV, 494.5 miles were 345-kV and 262 miles were 500-kV.
FERC estimates that 12,796.7 miles out of the 23,343 miles proposed to be in service by May 2014 have a high probability of completion. The majority of these projects are proposed in the Western Electricity Coordinating Council (WECC) and the Texas Reliability Entity (TRE).
