Barr provided engineering services for two 100 to 105 MW windpower projects now in service in central North Dakota: Minnesota Power’s Bison 2 and Bison 3 projects. We conducted geotechnical investigations for, and designed, turbine foundations, roads, and crane paths, and also designed the electrical collection system.
In concert with engineering services for the Bison 2 and 3 projects, Barr provided environmental permitting support. Our engineering and permitting teams worked closely together to identify risks and deliver final site layouts and designs that satisfied regulatory requirements—such as avoiding construction in wetlands—while meeting the client’s construction schedule and energy production goals.
