Ratepayers in Wyoming will be expected to foot the $2 million bill for the new mandate to retrofit coal-fired power plants with carbon capture.
Namely, customers of Rocky Mountain Power will be faced with a 0.3% rate increase starting February 2023.
The surcharge was approved on Thursday by the Wyoming Public Service Commission and is expected to cover the estimated $2 million needed to equip the state’s coal power plants with carbon capture, utilization and sequestration (CCUS) facilities.
Retrofitting coal-fired power plants is mandated by the state legislation that was passed last year, even despite the preliminary data that shows CCUS may be too expensive.
Black Hills Energy, another electric utility company in the state, has filed a similar request with the Wyoming Public Service Commission, although it has not yet asked for a carbon capture compliance rate hearing.
