PacifiCorp Weighs Options for Coal-fired Power Plants

LCG, April 27, 2012--PacifiCorp, a unit of MidAmerican Energy Holdings, announced yesterday that future federal and state environmental requirements for its coal fleet would cost over $1 billion in coming years. As a result, its fleet is expected to reduce coal consumption and increase reliance on natural gas.

The company is evaluating a number of options at its coal plants. To comply with state and federal air quality regulations to improve visibility in national parks and wilderness areas, the company has concluded that the preferred option is to convert the 330-MW Naughton 3 coal-fired unit in Wyoming to low-cost natural gas, rather than installing new emission controls for coal that will be required after 2014.

In Utah, PacifiCorp is evaluating compliance options in response to the utility mercury and air toxics standards (MATS) at its 172-MW Carbon coal-fired plant. At this time, the company has determined the lowest cost option for the aging Carbon plant is to decommission the facility, although additional options are still be being pursued.

PacifiCorp is also developing other gas-fired facilities, including the construction of a 637-MW natural gas-fired, combined cycle plant at its Lake Side facility south of Salt Lake City. The new facility is scheduled to commence operation in the summer of 2014.
