No transmission projects were completed in the month of April, compared to 71 miles of transmission lines in the same month last year, according to FERC’s monthly energy infrastructure update.
Compared to 2011, 2012 has seen a steep drop-off in terms of completed transmission projects. As of April 30, 98.6 miles of transmission lines had been completed in 2012, comprising 9.6 miles of 230-kV (and below) lines, 10 miles of 345-kV lines, and 79 miles of 500-kV lines. Of that, six miles were 230-kV (and below) lines and 65 miles were 500-kV lines. No 345-kV lines were completed in April.
In 2011, a total of 1,985.6 miles of transmission lines were completed, comprising 1,152.7 miles of 230-kV (and below) lines, 570.9 miles of 345-kV lines, and 262 miles of 500-kV lines.
The proposed 345-kV transmission lines comprise the most miles likely to be complete by 2014, compared to the total number of miles proposed. There are 9.893.1 miles of 345-kV lines proposed to be complete, out of which 8,216.8 miles have a high probability of completion.
For lines that are 230-kV (and below), there are 6,416.3 miles proposed to be complete by 2014, of which FERC estimates 2,137.4 miles have a high probability of completion. For the 7,106.7 miles of 500-kV lines proposed, 2,502.1 miles have a high probability of completion by 2014.
