The Milford Wind Corridor Project is a 203 megawatt wind farm in Milford, Utah. The project was developed by First Wind. The wind farm has 97 wind turbines, including 58 Clipper Liberty 2.5-MW wind turbines and 39 GE 1.5 MW wind turbines.

The 203 MW Milford I project went online in November 2009 and supported more than 300 development and construction jobs. First Wind spent about $30 million with Utah-based businesses developing and building the first phase of the project. Another $50 million was spent statewide on items such as wages and taxes.

A second phase of the Milford Wind Corridor Project began in July 2010 and foundations were poured in October. The expansion will add another 68 GE 1.5-MW turbines for a total of an additional 102 MW.
  • Approximately 90 miles of new 345-kV transmission line for interconnection with the IPP substation near Delta, Utah
  • An interconnection facility (i.e., switching station) at the IPP substation for connection between the project transmission line and the IPP substation.

At the facility’s electrical substation, the voltage of the power being delivered by the Wind Energy Facility power collection system at 34.5 kV would be stepped up to 345 kV for delivery into the project transmission line. Delivery of the power to the IPP substation would require a new, approximately 90-mile-long, 345-kV transmission line crossing primarily BLM-managed lands.

The proposed transmission line route would follow one of two alternative routes. The first route (applicant’s proposed route) would travel west from the Wind Energy Facility to a point west of Arizona State Route 257, which it would follow generally north-northeast, diverging east, north, and then west around Delta, Utah, to it’s interconnection at the IPP substation. The second alternative transmission line route would generally follow a route that is parallel to the existing IPP transmission line. Similar to the applicant’s proposed route, the alternative transmission line would terminate at the IPP substation near Delta. Wooden H-frame or steel-lattice transmission line towers spaced at approximately one-quarter-mile intervals within a permanent trans transmission line cables. The transmission line towers would be up to approximately 164 feet high and would each occupy a permanent area approximately 20 feet by 30 feet. The Wind Energy Facility substation would occupy an area site of approximately 10-acres or less.
