Donated by Black Hills Power
The Neil Simpson I power plant at Wyodak was the first air-cooled power plant in the United States. This 80 MW coal-fired power plant went online in 1959 and went offline in 2014. It was demolished in 2015. Prior to demolition, the staff at the Rockpile Museum was able to salvage part of the plant's control panel. Now in storage, the museum hopes to have this control panel on display in the near future to tell the story of electrical generation in the Powder River Basin.
