TULSA, Okla., Nov. 1, 2004 – Public Service Company of Oklahoma (PSO) today announced a Request for Proposals (RFP) for renewable energy to help fulfill energy-supply requirements for its customers.
 
The request was issued for PSO and its sister company, Southwestern Electric Power Co. (SWEPCO), by parent company American Electric Power (NYSE: AEP). Proposals for up to 250 megawatts of renewable-energy generation within the Southwest Power Pool, which includes PSO and SWEPCO, are due Dec. 1, 2004. AEP expects to complete agreements with any successful bidders in March 2005.
 
AEP is seeking bids from renewable-energy providers that could place new generating facilities into service by Dec. 31, 2005. The recently extended federal Production Tax Credit (PTC) provides owners of renewable resources a tax credit equal to $18 per megawatt-hour for 10 years beginning on the facilities’ in-service date. It applies to renewable energy resources that are operational by the end of 2005.
           
“This RFP is another demonstration of PSO’s significant commitment to providing cost-effective renewable energy for our customers,” said Stuart Solomon, PSO president and chief operating officer. “In June, PSO signed a 20-year contract to purchase up to 106.5 megawatts of Oklahoma-generated wind power, enough to supply the power needs of 31,000 Oklahoma customers.”
 
Generation technologies eligible to bid into the RFPs include wind, solar, hydroelectric, geothermal, biomass and biomass-based waste products, including landfill gas.
