Charlotte, North Carolina [RenewableEnergyAccess.com] Duke Energy Carolinas has issued a request for proposals (RFP) to purchase power or generation assets up to 800 megawatts (MW) of peaking and/or intermediate generation in the 2010 timeframe, and up to 2,000 MW of peaking and/or intermediate generation in the 2013 timeframe.“Buying power is one of the many strategies Duke Energy Carolinas explores to ensure customers have the energy they rely on,” said Ellen Ruff, president, Duke Energy Carolinas. “The company’s comprehensive generation plan also includes building new power plants, greater use of renewable energy and developing robust energy efficiency programs to reduce demand.” The company routinely surveys the competitive wholesale power market in search of the most economical and reliable options for customers. Through the RFP process, Duke Energy Carolinas is assessing how much peaking and intermediate generation is available and at what cost. Peaking power is typically needed when energy demand is greatest, often on hot summer days or cold winter mornings. Intermediate generation supplies power to customers on a more routine basis. Bids are due by July 20, 2007 and will be evaluated and negotiated over the next several months.
