Rate Tariffs

The Public Service Commission of Wisconsin (PSCW) provides information concerning Sun Prairie Utilities rate tariffs. To view a PDF version of the rate tariff, please click here. The rate tariff is also kept on file at the PSCW.

Nights & Weekends Smart Plan (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 Residential (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 8am-8pm, excluding Saturday, Sunday, and holidays.

The current regular RG1 rate is $..0922 per kwh. The current RG2 rates are $.1600 per kwh on-peak and $.0510 per kwh off-peak. At these rates, if your household can move 62% ot total usage (or more) to the off-peak period then RG2 would be a more beneficial rate.

The Nights & Weekends Smart Plan requires a 12-month commitment, so it is imperative that a household can move at least 68% 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 PSCW. 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.
