Construction of the 102 MW Oklahoma Wind Energy Center is not yet complete, but that is proving no barrier to sales of the plant's future output to private consumers. Oklahoma Gas & Electric (OG&E) took advantage of the Oklahoma State Fair to sign up customers for its wind power only option. It already has 720,000 retail customers. At the fair, the utility used a model of a working turbine and a full-size turbine blade to attract prospective buyers, while FPL Energy continued construction at the northwest Oklahoma wind farm. OG&E is buying 50 MW of the project's output, while the Oklahoma Municipal Power Authority is buying the remaining energy. FPL, which is erecting GE Wind Energy 1.5 MW turbines, says the project will be ready for commercial operation around late autumn.
