South Dakota Rate Review
We know many Americans are facing challenging times, and no one wants to see rising electric bills. We are also committed to providing reliable, sustainable energy service at the most affordable rates possible to our customers.
NorthWestern Energy requested a regulatory electric rate review in South Dakota as we continue to strengthen our electric system. The South Dakota Public Utilities Commission approved NorthWestern Energy’s settlement agreement with SDPUC staff which allows for an 11.38% increase in NorthWestern Energy total electric bills, or a 17.97% increase in base electric rates, from a $21.52 million increase in South Dakota electric revenues effective Jan. 10, 2024.
The rate increase will ensure that our customers will continue to be served by a financially sound company capable of efficiently funding the significant capital expenditures needed to maintain, expand and modernize our energy infrastructure.
We recognize that our rate increase will impact our customers during a period when other prices are also increasing, which is why we’re here to help customers who may be struggling with their bills. Customers concerned about their ability to pay their energy bill can contact NorthWestern Energy for information about energy assistance programs and to arrange flexible payment options.
How much will my bill increase?
For a typical electric residential customer using 750 kilowatt-hours per month, the approved rate increase will mean a monthly bill increase of:
$13.67
The increase represents a 1.42% yearly increase since the previous rates were established in 2015. Since then, NorthWestern Energy has invested $267 million in our South Dakota electric infrastructure to continue our commitment to providing reliable, sustainable energy service at the most affordable rates possible to our South Dakota customers.
Below is a sample of new rates, based on average use by customer class.
