Depending on when you use your energy, you might benefit from our program Nights and Weekends or Peak Nights and Weekends.
Nights and Weekends for Wisconsin customers
Electricity costs fluctuate every hour of the day. During the week, especially on hot summer days and dark winter evenings, costs increase due to high demand. On nights and weekends (and some holidays), demand for electricity goes down, which means so does the cost.
If you use high-wattage appliances like a water heater, air conditioner or electric clothes dryer, you could lower your bill by running those appliances after 7 p.m. on weekdays. You could save even more money if you use those appliances after 11 p.m. on weekdays or anytime during the weekend.
Please note there is an approximate $15 monthly charge that will appear on your bill when enrolled in Nights and Weekends (which is the same as the $15 monthly charge for WPL’s standard rate [Rg-1]). On the monthly bill, this rate is listed as RG-5 Residential Service.
Peak Nights and Weekends for Wisconsin customers
Peak Nights and Weekends is like Nights and Weekends but better for customers who use most of their energy before 10 a.m. and after 8 p.m. during non-holiday weekdays. This may be a good option if you drive an electric vehicle or use electric space heating.
When you enroll in Peak Nights and Weekends, you’ll receive your energy at a rate lower than the traditional nights and weekends rate. However, your bill will include a monthly peak demand charge of $4.80 charge per kilowatt for the highest hourly energy demand peak that happens between the hours of 10 a.m. and 8 p.m. Monday through Friday (all year). That means the single hour of your highest energy demand between those hours in a billing period is charged at $4.80 per kilowatt.
Example: If you used 3 kilowatts in a single hour between 10 a.m. and 8 p.m. and that was the largest energy demand in your billing cycle, you would be charged $14.40 for that month for the peak demand charge.
There is no monthly peak demand charge with energy used after 8 p.m. and before 10 a.m. or on the weekends. Please note there is an approximately $10 monthly charge when enrolled in Peak Nights and Weekends (as compared to the $15 monthly charge for WPL’s standard rate [Rg-1]). This program will appear on your bill as a RD-1 Residential Demand Service. See an example of how a bill would look.
