Step 2: Optimizing Your Operation

Operating Your Water Heater

A successful electrification project doesn’t just end at installation, getting on the right time of use rate and setting your water heater to load shift away from peak times are the key to a successful experience. Here are some simple steps to optimize your operation.

Set Up Your time-of-use Electric rate

There are a number of Time-Of-Use (TOU) electric rates and which one is best for you depends on how much electricity you use and when you use it.

We recommend using PG&E’s rate analysis tool to find out which rate will be best for you, then contact PG&E to get it changed.

Through the pilot, you can get rewarded by planning ahead, scheduling your equipment, and using power when its cheapest. This pilot is only recommended for customers with the ability to respond to load shifting signals. Click here for more information.

Enrolling in a load Shift Program

WatterSaver is a load shift program that will automatically set your water heater each day to optimize your water heater and is required to obtain bill credits. WatterSaver uses WIFI or cellular technology to communicate directly with your water heater to automatically optimize its operation to utilize the lowest cost of electricity.
