Oregon utility regulators on Tuesday turned down PacifiCorp's request to seek bids for construction of two conventional coal-fired power plants in Wyoming and Utah.
In a proposal filed last summer, PacifiCorp maintained it needed the additional resources by 2014 to meet growing demand in its six-state territory. But customer groups argued that the plants weren't needed and, if built, would harm the environment with carbon dioxide emissions, considered key contributors to global warming.
The Oregon Public Utility Commission based its rejection primarily on an independent analysis of how much electricity PacifiCorp's customers would need in six to eight years.
PacifiCorp "has significantly overestimated its resource needs," the PUC order concluded.
