Rock Port, Missouri is the first 100% wind powered city in the US. Loess Hill Wind Farm, with four 1.25 MW wind turbines is estimated to generate 16 gigawatt hours (16 million kilowatt hours) of electricity annually. 13 gigawatts hours of electricity have historically been consumed annually by the residents and businesses of this town of 1,400 people.
The local electric company, Missouri Public Utility Alliance, will purchase excess electricity when available. They will then supply power when there is not enough wind energy available. Excess wind energy will not be stored but rather fed into the city’s high voltage line, making it an intermittent source of power.
Several factors made this smaller scale project possible. The city has a bluff within the city limits with good resources, John Deere’s Wind Energy financing the project, and proximity to the power grid.
