Electric Rates & Extension Rules
Superior Water, Light and Power Company provides electricity within the City of Superior and six other communities within Douglas County, Wisconsin. By purchasing electricity at wholesale from Minnesota Power, a division of our parent company ALLETE, Inc., we are able to combine reliable service with rates that are among the overall lowest in the state of Wisconsin.
