A single 765,000-volt transmission line can move about 1% of the total average U.S. electric load. Thousands of miles of these lines are already up and running. It will take another 22,000 miles to knit the existing wires together into a national grid. This backbone will be able to move about 25% of our current electricity consumption over distances that span significant fractions of the continent. Electrical losses will be modest, because very high voltage lines are fantastically efficient. The backbone will cost $75 billion to build. It will add about 0.3 cents of transmission cost per kilowatt-hour to the retail price of electricity, which currently averages about 9 cents. By pooling demand, the backbone will let cheap power chase high demand around the clock and across the country. It will let inexpensive coal, uranium, water behind a dam or (eventually) wind, sun and other renewables displace expensive gas-fired power. It will lower the capital cost of electricity by allowing fuller use of billion-dollar power plants, much as filling every seat on a jumbo jet lowers the average cost of flying. A plant located in (say) Lebanon, Kans., the geographic center of the country, will be within easy reach of peak loads on both coasts and everywhere in between. By pooling supply and demand nationwide, the backbone will cut the average cost of generating electricity by somewhere between 30% and 50%. And it will reduce it still more over the longer term, by allowing producers to locate power plants where the land is cheap, the neighbors are friendly, the coal, uranium, gas, wind or sun is most readily available, the ecosystems are durable and the obstructive lawyers are scarce. By providing cheap access to the cheapest power, a backbone grid will also accelerate electrification. Plug-in hybrid cars will recharge mainly at night. Heating loads peak at night, too. Using idle capacity in plants and wires to compete in these two big, oil-dependent sectors will further level out supply and demand and thus further lower the cost of electricity. ...forbes.com
