Acquisition of a Wind Energy Generation Facility in Wisconsin

On April 2, 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 129 MW. The aggregate purchase price was $172.9 million of which our proportionate share was 44.6%, or $77.1 million. Since 2008 and up until the acquisition, we purchased 44.6% of the facility’s energy output under a power purchase agreement.

The table below shows the allocation of the purchase price to the assets acquired at the date of the acquisition, which are included in rate base.
