$this->bbcode_second_pass_quote('', 'U')nlike answers to many of the nation’s energy problems, improvements to the grid would require no new technology. An Energy Department plan to source 20 percent of the nation’s electricity from wind calls for a high-voltage backbone spanning the country that would be similar to 2,100 miles of lines already operated by a company called American Electric Power.
The cost would be high, $60 billion or more, but in theory could be spread across many years and tens of millions of electrical customers. However, in most states, rules used by public service commissions to evaluate transmission investments discourage multistate projects of this sort. In some states with low electric rates, elected officials fear that new lines will simply export their cheap power and drive rates up.
Without a clear way of recovering the costs and earning a profit, and with little leadership on the issue from the federal government, no company or organization has offered to fight the political battles necessary to get such a transmission backbone built.

Wind Energy Bumps Into Power Grid’s Limits$this->bbcode_second_pass_quote('', 'W')ind advocates say that just two of the windiest states, North Dakota and South Dakota, could in principle generate half the nation’s electricity from turbines. But the way the national grid is configured, half the country would have to move to the Dakotas in order to use the power.
“We still have a third-world grid,” Mr. Richardson said, repeating a comment he has made several times.
“With the federal government not investing, not setting good regulatory mechanisms, and basically taking a back seat on everything except drilling and fossil fuels, the grid has not been modernized, especially for wind energy.”
