With the Cg-20 Time-of-Use electric rate, your business pays for electricity based on
when you use it. Knowing when electricity is at its lowest prices each day gives you the
opportunity to manage your energy costs.
Electricity is most expensive to produce during the hours of peak electric use – weekday
hours that generally correspond with traditional business hours. When you opt to use a
greater amount of electricity during non-peak hours, WPS
passes the savings along to you through the Cg-20 Time-of-Use rate. Some commercial and
industrial customers have found they can save money simply by adjusting the time when they
perform some electric operations.
Who qualifies for this rate?
You do, if your business:
- has a total electric demand of at least 100 kilowatts for three months in a row, or
- consumes a total of at least 25,000 kilowatt-hours of electricity for three months in a row, or
- both of the above.
To remain on the Cg-20 Time-of-Use electric rate, your business must exceed at least one
of the above criteria during one month in each succeeding rolling 12-month period.
Simple changes mean real savings
Your business can save on its electric bill every month by using high-demand equipment at
times when there's low demand for electricity. When it's difficult to reduce the amount of
electricity you use; try to run your high-demand operations when power is less costly to

with any electric service — is when unexpected events, such as severe storms or vehicle
