3200 Utilities Make Up US Electrical Power Grid, But Technological Change Creates Uncertainty

From Bloomberg Businessweek, "Why the U.S. Power Grid's Days Are Numbered" by Chris Martin, Mark Chediak, and Ken Wells:
There are 3,200 utilities that make up the U.S. electrical grid, the largest machine in the world. These power companies sell $400 billion worth of electricity a year, mostly derived from burning fossil fuels in centralized stations and distributed over 2.7 million miles of power lines. Regulators set rates; utilities get guaranteed returns; investors get sure-thing dividends. It’s a model that hasn’t changed much since Thomas Edison invented the light bulb. And it’s doomed to obsolescence.

That’s the opinion of David Crane, chief executive officer of NRG Energy, a wholesale power company based in Princeton, N.J. What’s afoot is a confluence of green energy and computer technology, deregulation, cheap natural gas, and political pressure that, as Crane starkly frames it, poses “a mortal threat to the existing utility system.” He says that in about the time it has taken cell phones to supplant land lines in most U.S. homes, the grid will become increasingly irrelevant as customers move toward decentralized homegrown green energy. Rooftop solar, in particular, is turning tens of thousands of businesses and households into power producers. Such distributed generation, to use the industry’s term for power produced outside the grid, is certain to grow.

An unusually frank January report by the Edison Electric Institute (EEI), the utilities trade group, warned members that distributed generation and companion factors have essentially put them in the same position as airlines and the telecommunications industry in the late 1970s. "U.S. carriers that were in existence prior to deregulation in 1978 faced bankruptcy," the report states. "The telecommunication businesses of 1978, meanwhile, are not recognizable today." Crane prefers another analogy. Like the U.S. Postal Service, he says, "utilities will continue to serve the elderly or the less fortunate, but the rest of the population moves on."
