The town of Rock Port, Missouri, is the first wind-powered city in the United States. The wind farm consists of four Suzlon 1.25-megawatt wind turbines and will produce enough electricity to supply all the power needs for this town of 1,395 people.

The Missouri Public Utility Alliance in Columbia purchases excess electricity from Loess Hills when the output from the wind power plant exceeds consumption in the town. This alliance provides electricity to Rock Port Municipal Utilities, which distributes to customers in town. The wind farm is sized to provide enough electricity over the course of a typical year to match electricity consumption in the town.
