About the Program

The Residential Time-of-Day (TOD) Rate Pilot Program introduces a limited number of Seattle City Light customers to a new model of billing based on when they use electricity during the day. The pilot program will run from October 2020 through December 2022 or when opt-in TOD rates are available to all customers. At this time, enrollment for the pilot program is now closed.

Under TOD rate billing, participants may be able to save money on their electric bills by switching your energy use to “off-peak” hours of the day, which are shown in the chart below. Customers with high energy use are most likely to see lower bills with the TOD rate structure, especially if they take advantage of off-peak hour rates.

By participating in the program, participants will provide valuable information to City Light about how our customers choose to manage their energy use when given additional options. What we learn from the pilot program will help us prepare to offer opt-in TOD rates to additional customers in the future in a way that best meets their needs.

How the Rates Work

With City Light’s current residential rates, each customer can use up to a certain amount of energy at a lower rate. If customers use more than this set amount of electricity, this use is charged at a higher rate. Customers also pay a small daily base service charge. For more information about our current rate structure, see the Rates page on our website.

TOD rates give customers more control over their energy bills. TOD rates are based on when a customer chooses to consume energy. Customers will pay higher electricity rates during peak hours (5:00 – 9:00 p.m.) when electricity usage in our service area is normally high. Discounted rates will be offered during off-peak hours (12:00 – 6:00 a.m.) when electricity usage is low. TOD rates also include the base service charge.

Note: For this pilot, holidays are New Year’s Day, Memorial Day, Independence Day, Labor Day, Thanksgiving Day and Christmas Day

The peak rate period coincides with City Light’s highest electrical usage for the entire service territory. Customers currently use the most electricity between 5 p.m. – 9 p.m. This higher volume puts a strain on the utility, leading to higher costs. These periods also coincide with higher electricity prices on the wholesale market where City Light both buys and sells electricity.

Check out the graphic below to find out how much different common household appliances cost to run at different times of the day. When possible, participants in the program can reduce or shift their energy use away from 5 p.m. to 9 p.m., Monday to Saturday, to take advantage of lower off-peak or mid-peak rates.

Their savings will depend on the amount of electricity they use and when they use it.

Don’t worry; we won’t charge more if the TOD rate doesn’t save participants money! During this pilot program, we will calculate participants’ bills under the TOD pilot rates and the standard rates, and the lower of the two bills will be used.

Participants will be provided with a monthly report that shows their daily energy use patterns. Visit the Energy Solutions section on our website for more tips on how to take control of your energy use at home.
