A wind farm is a group of wind turbines in the same location used for production of electric power. Individual turbines are interconnected with a medium voltage power collection system and communications network. At a substation, this medium-voltage electrical current is increased in voltage with a transformer for connection to the high voltage transmission system. Two new large farms were announced recently. Mexico’s Grupo Bimbo, one of the world’s largest bread makers, has broken ground on its $200 million Piedra Larga wind farm in Oaxaca, Mexico, which will generate almost 100% of the electrical power consumed by all of Bimbo’s operations in Mexico once completed in late 2011. Deepwater Wind announced that it has applied to federal authorities to build what it what is supposed to be the largest offshore wind farm in the U.S. The application was made in late October to the Bureau of Ocean Energy Management, Regulation and Enforcement to lease a 270-square-mile area between Rhode Island and Massachusetts.
