Montana ranks fifth among the states for its potential wind power. Only the Dakotas, Texas, and Kansas are windier. The largest wind farm in the state opened in 2005 at Judith Gap. This farm has 90 1.5 megawatt turbines which extend more than 260 feet in the air. A Texas company is proposing a 300-megawatt wind farm near Martinsdale with more than 100 towers. At least 6 other major wind farms are being planned for Montana, with a total production of 900 megawatt if all of the projects are approved. Large wind farms are also being considered for Shelby and Glasgow.
