110-MW Sunflower Wind project up for North Dakota review

An application from Sunflower Wind Project LLC for a Certificate of Site Compatibility for a wind energy conversion project located in Morton and Stark counties is up for review at a June 12 North Dakota Public Service Commission work session.

Tetra Tech, on behalf of the Western Area Power Administration, sent a May 22 letter to the commission saying that an Environmental Assessment (EA) on the project is out for comment until June 20. The project involves the potential construction of an approximately 110-MW wind facility that includes up to 59 turbines, an underground power collection system, substation, access roads, and a maintenance and operation center. The project would produce up to 438,000 megawatt hours of electricity per year, which would enter the grid through an interconnection with Western’s Dickinson-to-Mandan 230-kV transmission line inside the project area.

The project will be located to the south of Hebron and west of Glen Ullin in Stark and Morton counties, N.D.

Sunflower Wind on May 19 filed proposed findings with the commission for this project. The project will consist of either up to 55 Vestas V-110 turbines or up to 59 General Electric 1.85-87 turbines. The Vestas turbines have a tower height of 262 feet, a rotor diameter of 361 feet, with a total height of 443 feet. The General Electric turbines have a tower height of 262 feet, a rotor diameter of 285 feet, with a total height of 405 feet. The Vestas turbines begin operation at 6.7 mph up to a maximum of 44 miles per hour. The General Electric turbines begin operation at 6.7 miles per hour up to a maximum of 56 miles per hour.

Construction of the project is expected to take six to nine months, at a total estimated cost of $180m. Sunflower anticipates that construction will start in the spring of 2015. Sunflower said it has entered into a Power Purchase Agreement with Basin Electric Power Cooperative, dated Nov. 6, 2013.

Sunflower Wind Project LLC is a wholly owned subsidiary of Infinity Wind Power.
