The Single-Phase Time-of-Use Rate (SPTOU) is designed for consumers who are able to shift more of their electricity use to lower demand or off-peak periods. This rate more accurately passes along the real-time cost of electricity. Electrical energy is more expensive during periods of high demand and less expensive when demand is low. By choosing the Time-of-Use Rate and shifting electricity use to lower-demand time periods, you can save money on your electric bill.
Here are some common questions about this rate to help you decide if it is right for you.
Electricity prices vary based on the time of day; the day of the week – weekday vs. weekend; and by season – spring and fall vs. winter and summer. The Time-of-Use Rate program bases the cost of electricity on when it is used and our cost to supply it during that time. Electricity that is used when demand is low is known as off-peak, and has a lower cost than electricity used during periods of high demand, or on-peak.
Off-peak hours account for about 94 percent of the hours in a year and electricity used during these times is discounted by 25 percent. The remaining 6 percent of hours in a year are on-peak and electricity used during these times is charged a premium.
Summer On-Peak Energy: $0.375 per kWh
Winter On-Peak Energy: $0.3 kWh
All Off-Peak Energy: $0.075 per kWh
On-peak hours are defined as follows:
Off-peak hours are all remaining hours. The charts below illustrate both on-peak and off-peak time periods.
If you are able to control when you use electricity, or if you can shift more of your usage to off-peak times, you may benefit from this rate. Things to consider:
