This week, the connection and New England, Canada submarine high-voltage direct current transmission project of New England Clean Power Link through Vermont formal regulatory committee for approval.
According to the introduction, of the high-voltage direct current transmission cable, 154 - a mile transmission capacity of 1000 megawatts (mw), the total cost is about $1.2 billion (RMB 7.9 billion).
TDI project developers New England power transmission company chief executive Don Jessome said, "Getting the regulatory approval state of Vermont is an important step in the whole project completion approval.
We hope to get the second half of the federal energy regulatory commission's approval.
In this way, the submarine high-voltage direct current transmission project is expected to start construction in 2017, and was completed in the middle of 2019."
New England Clean Power Link project development has faced rival Eversource energy companies in the United States in the development of Northern Pass competition of underground cable.
Both sides insist that their respective cable design path scheme is clean and environmentally friendly. New England is to clean water and electricity resources, reducing the use of fossil fuels.
Eversource energy thought, the design of the Northern Pass path length is about 192 miles, but a third of them adopt the method of the cable into the ground.
This is more than New England Clean Power Link submarine high-voltage direct current transmission cost is much lower.
