ConEdison Acquires 19.5 MW Wind Farm In S.D.


Consolidated Edison Development (ConEdison) has acquired a 19.5 MW wind project, located on a family ranch in Clark County, S.D.

The Oak Tree Wind Farm will be powered by 11 GE 1.85-87 wind turbines and is expected to generate approximately 71,000 MWh of power annually. The project, which ConEdison will also operate, is in final testing and will be operational when testing is completed, the company notes.

According to ConEdison, the project is the vision of ranch owner Bill Makens, who used a portion of his ranch land to develop the wind farm. Makens partnered with Gary, S.D.-based Diversified Energy Solutions and Farmington, Minn.-based Consulting Engineers Group to design and build the project. Pipestone, Minn.-based Juhl Energy also provided development support services.

‘For more than 114 years, the Makens family has proudly demonstrated our love for South Dakota's land and its natural resources,’ says Makens. ‘Over the generations, our family has been fortunate to serve as environmental stewards of our holdings, while also finding ways our property can serve the community at large.’

NorthWestern Energy has agreed to purchase the project's output under a 20-year power purchase agreement. The wind farm is interconnected with NorthWestern Energy and the Western Area Power Administration transmission systems.
