Rates

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.

Residential Optional Time of Day (RG2): Residential customers have the option to apply for Time of Day rate option. This structure defines a peak time period for on-peak at which all consumption used is charged a higher cost than regular Resdential (RG1). Likewise all consumption not used on-peak is considered off-peak and all off-peak consumption is charged a lower cost than RG1. The on peak period is defined as Monday- Friday between either 7am-7pm, or 8am-8pm, or 9am-9pm, excluding Saturday, Sunday, and holidays.

The current regular RG1 rate is $.1005 per kwh. The current RG2 rates are $.1760 per kwh on-peak and $.0560 per kwh off-peak. At these rates, if your household can move 67% ot total usage  (or more) to the off-peak period then RG2 would be  a more beneficial rate.

RG2 rates require a 12 month commitment and so it is imperative that a household can move at least 67% of total monthly consumption to the off-peak period. If not, they would be paying more premium on-peak costs and would be paying in total more than on the regular RG1 rate.

 

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.
