Background
The power station is part of the Neil Simpson Complex, along with several other plants: Neil Simpson 1 (1970), Neil Simpson 2 (1995), and Wygen I (2003). All these plants use coal from the nearby Wyodak Mine.[1]
The state air permit for Wygen II power station was opposed by the National Park Service, due to pollution impacts on the Badlands and Wind Cave National Monument.
Wygen II power station went into operation on January 1, 2008.[2]
Carbon Capture and Storage plans
In January 2024, the Wyoming Public Service Commission approved an application from Black Hills Energy for a 0.67% "low-carbon" surcharge on its 145,000 customers starting in February 2024. The surcharge would be applied under the provisions of a 2020 law requiring coal plants to be retrofitted with carbon capture and storage (CCS) technology as an alternative to closing. Black Hills Energy reportedly expected CCS to cost US$500 million at the Wygen II plant.[3]
In February 2024, the Wyoming Public Service Commission (PSC) said it would delay a decision on Black Hills Energy's request for a one-year extension to submit a CCS retrofit plan for its Wygen II power station and Neil Simpson Plant II. Black Hills Energy was originally required to file a plan in March 2024 for how it will meet the state's CCS mandate, which was set in 2020. The commission's deferred decision would allow sufficient time to consider possible changes to the CCS mandate, as lawmakers were seeking to push the retrofit compliance deadline from 2030 to 2033.[4]
In early March 2024, the Wyoming House of Representatives approved a bill that delays the CCS retrofit compliance deadline to 2033, and allows utilities to pass the costs onto electricity customers.[5]
