ACQUISITION ACQUISITION

Acquisition of a Wind Energy Generation Facility in Wisconsin

In April 2018, we, along with two unaffiliated utilities, completed the purchase of Forward Wind Energy Center, which consists of 86 wind turbines located in Wisconsin with a total capacity of 138 MW. The aggregate purchase price was $172.9 million of which our proportionate share was 44.6%, or $77.1 million. In addition, we incurred transaction costs that are recorded to a regulatory asset. Since 2008 and up until the acquisition, we purchased 44.6% of the facility’s energy output under a power purchase agreement.

Under a joint ownership agreement with the two other utilities, we are entitled to our share of generating capability and output of the facility equal to our ownership interest. We are also paying our ownership share of additional capital expenditures and operating expenses. This acquisition was accounted for as an asset acquisition.
