Residential electric costs in Sun Prairie are lower than those charged by many investor-owned utilities in Wisconsin. Because community-owned utilities do not operate to make a profit, you pay only for the cost of service. This requirement is what allows Sun Prairie Utilities to provide highly competitive electric rates.

Power Cost Adjustment Clause (PCAC) 

This is a variable component of our rates as approved by the Wisconsin Public Service Commission (PSC). The Power Cost Adjustment Clause (PCAC) is a monthly pricing adjustment comparing actual purchased power costs to allocated costs as approved by the PSC. If actual costs are greater than the allocated, the result is an additional per-kilowatt hour charge on your bill. If actual costs are less than allocated, the result is a per-kilowatt hour credit on your bill. The PCAC assures you are only paying the actual costs associated with your actual consumption.
