The seasonal change is in peak-hour pricing
Colorado Springs Utilities switched Energy Wise accounts to winter rates October 1. Its September 22 notice says the residential on-peak rate falls from approximately 29 cents to 15 cents per kilowatt-hour, while the off-peak rate stays about 7 cents. The seasonal peak-rate drop is not a promise that the entire bill falls by half.
The winter period runs through May 31, with peak hours on weekdays from 5 to 9 p.m. Weekends and most holidays are off-peak. The utility says winter Energy Wise customers pay about five percent less on average than under the previous flat-rate structure, but actual usage patterns still matter.
Usage still determines the result
A separate fuel-cost-adjustment decrease also starts October 1. The utility estimates a $1.54 monthly reduction for the average residential customer. That is an estimate tied to a bill component, not a fixed grant or refund paid to everyone regardless of consumption.
The current rate page identifies Energy Wise as a time-of-day plan for most smart-meter residential and business accounts, with exclusions including net-metering service. Check the actual account plan before applying these figures. Shifting discretionary use outside peak hours can change the bill under this rate, but the useful comparison is your usage and full tariff, not only the largest percentage in the announcement.
