TempWise Pilot

Smart Thermostat and Phone App Photo

Help your community save energy during critical times while you earn rewards with Seattle City Light’s TempWise! This program is a limited pilot and enrollment is based on a first-come, first-served basis. Participating is easy and connecting your smart thermostat takes just a few minutes.

What is the TempWise Pilot Program?

TempWise is a new program that rewards you for participating in energy-saving events with your smart thermostat. This program was started to help us continue to deliver affordable and reliable power to the community during demand spikes. These spikes usually happen during very hot days in summer or very cold days in winter, or when the grid is constrained.

What is an Energy-Saving Event?

At times when energy usage in your community is exceptionally high, City Light will make small temperature adjustments to your smart thermostat to reduce the energy use of your central air conditioner, electric furnace, heat pump, or electric baseboards. These changes are no more than 3 degrees and last no more than 3 hours. There will be no more than 15 events per season (in winter or summer), and events will only occur during times of peak demand on non-holiday weekdays. You can opt out of an event at any time, for any reason.

Earn Rewards

Eligible participants will receive a one-time $50 check after successfully enrolling. For staying enrolled through the end of the season with an eligible system, you can earn up to $40 annually ($20 per season). See TempWise terms and conditions for more details.
