South Dakota Rate Review
In April 2018 we asked the South Dakota Public Utilities Commission (SDPUC) to first review the costs we incur to provide our customers with energy and related services and then determine how much our customers should pay for those services.
In May 2019 the South Dakota Public Utilities Commission (SDPUC) approved a revenue increase for our company of approximately $2.2 million, or about 6.6%.
The increase is more for some customers and less for others, depending on the rates on which they’re served and the amount of energy they use.
Rate Review Drivers
As the second smallest investor-owned utility in the country, our size gives us unique perspective into the small, rural communities we serve. With those communities and customers in mind, we make smart, innovative business decisions to ensure the prices they pay for reliable energy and top-notch customer service continue to be among the lowest in the country.
|Stronger, cleaner infrastructure||Smarter technologies||Rising costs|
|For example, required environmental technologies at coal-fired Big Stone Plant allow us to continue using this low-cost baseload resource. Transmission projects efficiently move energy produced in the region and improve reliability of the energy grid.||Technologies allow customers to get more for their energy dollar. For example, our new Customer Information System will allow customers more access and options related to their energy use and our services.||The SDPUC established our current base rates in 2011 based on 2009 costs. Since then costs we incur to provide our customers with energy and related services have increased, so it's time for the SDPUC to review them again.|
