The earliest utilities were neighborhood affairs. Thomas Edison's first central power plant in lower Manhattan generated 72 kilowatts and served 59 customers in 12 city blocks. But technological improvements gradually pushed small power plants off center stage, and independently produced power virtually disappeared, falling from 60 percent of all electricity generated in the United States in 1900 to less than 4 percent in 1980.
Then the trajectory abruptly changed. Rising interest rates in the 1970s made it increasingly expensive to build large power plants, while rising electricity prices and a weakening economy slowed demand. In the 1980s, utilities lost billions of dollars because of unneeded giant power plants.
Congress had abolished the electric-utilities monopoly in 1978. Utilities were required to purchase electricity from independent producers as long as these producers relied on renewable fuels such as wind or sunlight, or on higher-efficiency cogeneration technology.
The independent power industry grew so rapidly that by 1990, most new electrical capacity was owned by non-utility enterprises. The size of a typical independently owned power plant built that year was closer to that of one built in 1925 than to one built in 1975. And the trend is accelerating. The 30-kilowatt power plant manufactured by California-based Capstone, for example, is a washing-machine- sized microturbine that can supply the electrical needs of a small office building or restaurant.
Hospitals in Ontario and California, airports in New York and Michigan, and breweries, retail stores and restaurants in Illinois have already installed their own power plants. Decentralized power is going mainstream.
