To meet goals for providing clean, sustainable and affordable energy to all of our customers, PSE launched a Time-of-Use (TOU) pilot program this fall.

Through the pilot, a limited number of residential electric customers were recruited to enroll in the two-year program to study the impacts of encouraging them to shift when and how they use energy in their homes. The purpose of the pilot is to help us develop a time-of-use rate structure that can effectively shift power use away from peak demand times – to maintain reliability, conserve energy, and potentially drive cost savings for you.

While open recruitment has ended, some residential electric customers may still enroll in a TOU rate plan, pending limited availability. If you already enrolled in the TOU pilot program, you can log in to your PSE account to see more details about your TOU rate plan.


The pilot program is now fully subscribed for the purpose of the study. Some residential electric customers may still enroll in a TOU rate plan, however, pending limited availability.

When and how you use electricity matters

Time-of-use (TOU) rates are an easy way for electric customers who have the flexibility to shift when they use energy-intensive appliances and electric heating/cooling systems away from “peak” periods to save money on their monthly bill. Peak periods are typically from 7 a.m. to 10 a.m. and 5 p.m. to 8 p.m. on weekdays when demand and costs are highest. On a TOU rate plan, customers will also pay less for electricity during “off-peak” periods and on weekends and holidays.

TOU rate options will be available to more electric customers after completion of the pilot program. Find more ways to increase your efficiency, manage your use and lower your bill at
