The utilities have filed for a certificate of public convenience and necessity with the Wyoming Public Service Commission (PSC) to construct and operate the power plant in Cheyenne.
The facility will include one simple-cycle combustion turbine unit with a net capacity of about 37MW that will be wholly owned by Cheyenne Light.
The proposed plant will also include one combined-cycle unit with a net capacity of about 95MW that will be jointly owned by Cheyenne Light and Black Hills Power.
If approved by the PSC, construction of the plant will begin in 2012, with the facility expected to commence operation in 2014.
