The PUC provides these links to electric, natural gas, telephone and wireless telecommunications service providers to help you know more about the companies that serve you.

Utilities serving South Dakota communities
This handy reference (88 KB) lists the companies that provide electric, natural gas and local telephone service for South Dakota communities.

Investor-Owned Electric Utilities
There are six investor-owned utility companies that provide electric service to specific geographic areas in South Dakota that are regulated by the PUC. These companies are owned by their investors and are managed as private enterprises.

Electric Cooperatives
More than two dozen electric cooperatives provide power to rural customers and residents of many South Dakota towns. Each customer is a member and owner of the co-op. The business of the co-op is directed by its general manager and governed by a board of directors, elected by its membership. Three power cooperatives – Basin, East River and Rushmore – are generation and transmission cooperatives. These organizations provide electricity to their member co-ops that, in turn, deliver the power to their customers.

Municipal Electric Utilities
Several South Dakota communities are served by a municipal electric utility. The city owns the utility to supply electric services to residents in that community. The local government entity manages the operation.

Natural Gas Utilities
Three investor-owned natural gas companies provide service to South Dakota customers: Montana-Dakota Utilities Co., MidAmerican Energy Co., and NorthWestern Energy and are regulated by the PUC. The communities of Crooks, Garretson, Humboldt and Watertown are served by municipally-owned natural gas utilities.
