Controlled Water Heating

Electric Hot Water Heating Savings Program


Are you looking for ways to save on your electriTown costs? Do you have an electric hot water heater?* If you heat your hot water with electriTown, you can cut your electriTown costs and help the environment by participating in Concord Municipal Light Plant’s (CMLP) controlled water heating program. We currently have a network of more than 360 Concord residents enrolled.

*We recommend a minimum hot water tank size of 50 gallons (larger is better) in order to provide you with enough stored hot water for your needs during the times  we control your hot water heater.

ElectriTown During Peak Hours


ElectriTown is more expensive during certain times of the day, known as peak hours, when we need more energy to operate appliances, air conditioners, computers, etc. CMLP looks for ways to decrease demand during these peak hours with programs such as with our controlled water heating program.

How the Program Works


We will install a switch on your electric water heater to allow us to turn it off daily (for approximately 4 hours) when power is most expensive and generated by the least efficient plants.

Each month we will give you a credit of $14.87 on your bill for participating in the program. The credit represents the costs avoided by CMLP when controlling your water heater each month of the year.

Switch Installation


We will install a new meter and electronic switch that communicate with our load management system. The switch will be located inside near your water heater, so we need to schedule an appointment with you to install the new equipment. The appointment will take approximately one hour, and there will be a brief interruption of power for up to 30 minutes while the new switch for your water heater is installed.

Service to your electric water heater will be available for a minimum of 18 hours each day. Currently, we are turning off the water heaters for 4 hours daily.

Billing Cycle Alteration


If you currently have a bi-monthly billing cycle, this will change to monthly billing. We will read your meter on the 20th of each month, and you will be billed on the 30th. Please note the first meter reading may be either more or less than your normal billing, but will even out the following month.
