Proposed Carbon Rules Studied For Possible Impact on Apache Generating Station

June 2 2014

BENSON – The U.S. Environmental Protection Agency’s (EPA) proposed carbon limits for existing power plants like the Apache Generating Station south of Willcox is being studied for the possible impact it may have on future operations.

The EPA has proposed limits on carbon dioxide emissions for existing power plants that would cut overall carbon emissions by 30 percent from 2005 levels by the year 2030. How it plans to achieve that goal is outlined in a document of more than 600 pages.

“We are reviewing the proposed ‘carbon rules’ very carefully, and it’s too early in the review to determine the exact impacts on the Apache Generating Station,” said Geoff Oldfather, communications manager for Arizona’s G&T Cooperatives.

“As always, we’re determined to work with the EPA and all other stakeholders to achieve the best possible outcome for the environment, our operations and employees, and the people who rely on us for safe, reliable and affordable electric power,” Oldfather said.

“We appreciate that the EPA is allowing 120 days for public comment on the proposal, and we want to ensure the final language provides for flexibility to rural cooperatives like Arizona Electric Power Cooperative (AEPCO), which owns the Apache Generating Station,” Oldfather said.

Arizona’s G&T Cooperatives

Arizona Electric Power Cooperative (AEPCO), Southwest Transmission Cooperative (SWTC) and Sierra Southwest Cooperative Services collectively make up Arizona’s G&T Cooperatives.

AEPCO owns and operates the 605 (combined gross) megawatt Apache GeneratingStation at Cochise, Arizona, east of Benson.SWTC owns and maintains more than 620 miles of transmission lines and 27 substationsthat transmit wholesale power from the Apache Generating Station to six Member DistributionCooperatives in southern Arizona, northwestern Arizona in Bullhead City and Mohave County, and Anza in California. Combined, the Distribution Cooperatives that receive AEPCO’s wholesale power serve more than 150,000 meters representing more than 350,000 individual residential, commercial, agricultural and industrial customers.

The six Class A Member Cooperatives that receive wholesale power from AEPCO include five in Arizona; Sulphur Springs Valley Electric Cooperative in Willcox, Duncan Valley Electric Cooperative in Duncan, Graham County Electric Cooperative in Pima, Trico Electric Cooperative in Marana, Mohave Electric Cooperative in Bullhead City, and the California member, Anza Electric Cooperative in Anza. These member cooperatives own the Arizona’s G&T Cooperatives and by extension, the G&T Cooperatives are owned by their members, the people at the end of the line who use the power. The cooperatives are also Rural Utilities Service (RUS), a federal agency, borrowers.

The G&Ts and its member cooperatives are not-for-profit utilities.
