More than 32 mostly coal-fired power plants in a dozen states will be forced to shut down and an additional 36 might have to close because of new federal air pollution regulations, according to an Associated Press survey.
Together, those plants — some of the oldest and dirtiest in the country — produce enough electricity for more than 22 million households, the AP survey found.
The survey, based on interviews with 55 power plant operators and on the Environmental Protection Agency’s own prediction of power plant retirements, rebuts claims by critics of the regulations and some electric power producers.
The AP surveyed electricity-generating companies about what they plan to do and the effects on power supply and jobs. It was the first survey of its kind.
The estimate also was based in part on EPA computer models that predict which fossil-fuel generating units are likely to be retired early to comply with the rules, and which were likely to be retired anyway.
The agency has estimated that 14.7 GW, enough power for more than 11 million households, will be retired from the power grid in the 2014-15 period when the two new rules take effect.
