Celebrate Public Power in Sun Prairie
Sun Prairie is a Public Power community. This means the community owns the utility, has local control over policy and decisions, and employs many of your neighbors to serve you right here in Sun Prairie. This also means that SPU is celebrating Public Power Week (Oct 1-Oct. 7) this year with our first ever Photo Scavenger Hunt.
