A 100-mile power line at 765 kilovolt carrying 1000 MW of power can have losses of 1.1% to 0.5%. China’s 1.1 megavolt line can have power losses that 10 to 20 times less than 345 kilovolt lines. When fully operational the link will be capable of transporting 12,000 megawatts of electricity over 3,000 km. China’s high voltage grid will be nearly 23,000 miles long. It will be able to deliver about 150 gigawatts of electricity. This is roughly the output of 150 nuclear reactors. In a study published in Nature in 2016, it was reported that using high-voltage direct-current lines to integrate the US grid could cut electricity emissions to 80% below 1990 levels within 15 years…read more.
