Plains and Eastern Clean Line Project

Plains & Eastern is a 700-mile, 600-kV transmission HVDC line that originates at Diamond Substation, Okla., and terminates at Memphis Substation, Tenn. The project is proposed by Clean Line Energy Partners and is estimated to cost $2.5bn. The project, with a capacity of 4,000 MW, will connect renewable energy produced in Texas, Oklahoma and Kansas to population centers in the east. The project will make possible more than $7bn of new renewable energy projects. Originally, the project was planned as two 3,500 MW phases for a total project cost of $3.5bn. A spokesperson for Clean Line told TransmissionHub in June 2013 that the company may develop a second line at a later date.  Plains & Eastern is estimated to create more than 10,000 direct temporary construction jobs and over 1,000 direct permanent jobs maintaining and operating the wind farms and the transmission lines.
