With typical capacity factors between 30% and 40% for commercial wind farms, major wind developers would do a lot to find a site that would make real a 48% capacity factor wind farm. Real it is, however, at the East River Electric Cooperative's community wind farm in South Dakota.
Almost as remarkable as the 48% capacity factor achieved by the 10 megawatt community wind farm is how the installation was financed. Six hundred of the Coop's customers provided more than $16 million of capital for the $21 million project.
Even before the 48% capacity factor was achieved, the customers investments looked good. Now they are golden.
