Oklahoma Gas & Electric Company (OG&E) is a regulated electric utility company and subsidiary of OGE Energy Corporation that serves approximately 754,840 customers in Oklahoma and western Arkansas, and a number of wholesale customers throughout the region.[1] OG&E is the largest electric utility in the state of Oklahoma, with an interconnected transmission and distribution system spanning 30000 square miles.

OGE Energy Power portfolio

Out of its total 6,964 MW of electric generating capacity in 2005 (0.65% of the U.S. total), OGE produced 59.0% from natural gas and 41.0% from coal. All of OGE's power plants are in Oklahoma.[2]

Existing coal-fired power plants

OGE owned 5 coal-fired generating stations in 2005, with 2,854 MW of capacity. Here is a list of OGE's coal power plants:[2][3][4]

Plant Name State County Year(s) Built Capacity 2007 CO2 Emissions 2006 SO2 Emissions
Muskogee OK Muskogee 1977, 1978, 1984 1716 MW 10,600,000 tons 36,704 tons
Sooner OK Noble 1979, 1980 1138 MW 7,308,000 tons 16,579 tons

In 2006, OGE's 2 coal-fired power plants emitted 17.9 million tons of CO2 and 53,000 tons of SO2.

Canceled Coal Plants

In January 2007, OG&E filed a six-year construction plan with the Oklahoma Corporation Commission for the Red Rock Generating Facility. The plan included the construction of a 950 MW generating plant that would be owned in partnership with AEP-Public Service Company of Oklahoma and the Oklahoma Municipal Power Authority.[5]

The Oklahoma State Legislature approved the process in 2005.[6] Chesapeake Energy Corp, the third largest independent gas producer in the US, and the Quality of Service Coalition, a group of utility consumers and cities that purchase power from a subsidiary of American Electric Power, asked the Oklahoma Supreme Court to stop the Oklahoma Corporation Commission from considering pre-approval of the Red Rock Plant.[7][8]

On Sept. 10, 2007, with a 2-1 vote, the Oklahoma Corporation Commission denied the pre-approval permit for the plant, arguing that the utilities had not proven that they had sufficiently explored alternative forms of energy.[9] Oklahoma State Treasurer Scott Meacham also appeared in newspaper advertisements critical of the project.[10] On Oct. 11, the sponsors announced that they were discontinuing the project.[11]

Clean Air Act Regulations

As of December 2009 OG&E is fighting the construction of mandated pollution controls at two of its coal plants. As required by 1992’s federal Clean Air Act, states must reduce sulfurous emissions that hamper visibility, such as OG&E plants contributing to the "regional haze” at Oklahoma's Wichita Mountains Wildlife Refuges. Lessening the haze would require the construction of scrubbers at the OG&E plants. However, OG&E has argued that the scrubbers would be very expensive, and has proposed a cheaper alternative, but it has been rejected for not meeting EPA regulations. OG&E has said they will reach the desired emission level by 2026 by switching to natural gas, instead of coal, to generate the majority of its electricity, and that installing scrubbers will only encourage the continued use of coal plants.[12]

The Sierra Club also backs the company's complaint stating that installing scrubbers at an estimated cost of $1 billion may delay the company's transition from coal to natural gas. The scrubbers would reduce sulfurous emissions that contribute to regional haze, however the scrubbers would not reduce carbon dioxide emissions.[13]


On May 19, 2011, it was announced that Oklahoma Gas and Electric will pay $300,000 to the state Department of Environmental Quality for violating clean air regulations. Company spokesman Brian Alford said OG&E officials had been talking to DEQ about how to interpret regulations dealing with opacity - the measurement of how much light passes through smoke from a coal plant. OG&E agreed to reduce emissions from its coal plants, which DEQ indicated had repeatedly violated opacity standards since 2005. DEQ filed a lawsuit on May 17 in Oklahoma County District Court against OG&E over the violations, along with a consent order reflecting a settlement in the case. OG&E will pay a civil penalty of $150,000 and contribute an additional $150,000 to DEQ’s Small Community Supplemental Environmental Project Fund, as well as taking steps to reduce emissions.[14]
