Proposed Coal-fired Power Plant Denied by Oklahoma Commission
LCG, September 11, 2007--The Oklahoma Corporation Commission (OCC) yesterday issued an oral order that it would deny an application to build the Red Rock coal plant, a joint venture of American Electric Power-Public Service Company of Oklahoma (PSO), Oklahoma Gas & Electric Company (OG&E) and the Oklahoma Municipal Power Authority (OMPA).
The utilities had proposed to construct a 950-MW, ultra super critical coal-fired generating facility adjacent to an existing OG&E plant in north-central Oklahoma. The new unit would be operated by OG&E and would burn low-sulfur coal from the Powder River Basin in Wyoming. PSO would own 50 percent of the plant; OG&E 42 percent and OMPA 8 percent. The estimated cost of the new facility is $1.8 billion, and operations had been scheduled to commence by 2012. The utilities announced the proposal in July 2006.
According to a press release issued yesterday by PSO, the vote to deny the application was 2-1. The decision reverses a favorable recommendation from a hearing judge issued in August. PSO anticipates a final order by next week.
PSO and OG&E had proposed to rely upon new, coal-fired generation rather than gas-fired generation to provide a more cost-effective power supply. The utilities also pursued a commission order that would state that the new generation would be needed to ensure that the significant project costs would be recovered.
The plant was opposed on environmental grounds, including concerns regarding global warming, and economics relative to gas-fired generation, especially if additional potential costs for carbon emissions were included.
