Fixed Time of Delivery Rate

Keep your energy delivery to off-peak hours and store heating and cooling power.

Take advantage of one of our lowest energy rates

Fixed Time of Delivery is about half the price of our standard priced energy. And it’s available for those who use or are planning to use thermal-storage systems.

It’s our Fixed Time of Delivery Rate—and in addition to being the lowest priced rate we offer, you can qualify for up to $40 per kilowatt in rebates on your newly installed system!

The Fixed Time of Delivery Rate provides electricity during the low-demand overnight hours to charge your heating or cooling system. Electricity is delivered for 8 hours a day, from 10 p.m. to 6 a.m. Your thermal-storage system stores energy for heating or cooling—and, if you are planning to install one, you may qualify for rebates.

Eligibility and details

Fixed Time of Delivery rates are available for permanently connected, thermal storage systems,, and other approved equipment, including Level 2 EV charging systems. The rate includes options for self-contained (typical) metering, current transformer (CT) metering, or primary CT metering systems.

Systems must be designed with adequate storage capacity to heat or cool operate on this schedule of energy delivery. That means you'll want to work with your contractor to properly size your system.

Energy is delivered from 10:00 p.m. to 6:00 a.m. All other hours of service are unauthorized and subject to a penalty. Consistent usage outside of these hours will result in the rate being discontinued.
