Transmission line loss
(Posted November 26, 2007)
The transmission and distribution grid system within the United States loses approximately 7.2% of the energy
to resistance. Given 500,000 MW of energy available on the U.S. grid system, up to 36,000 MW may be lost, representing nearly 3x the installed capacity of wind in the country. If wind facilities are built far from load centers and the energy delivered via an extensive transmission network, it's reasonable to ask how much of this energy actually reaches its destination.
