Peak Time Rebate Program FAQs

In order to participate you must:

  1. Be a Flathead Electric Cooperative member in the Flathead or Lincoln County service areas and be a residential or small business customer.
  2. Have at least one electric water heater located in your primary residence or place of business.

Renters may participate, but must provide a landlord agreement form signed by their landlord.

Participation is free and voluntary. Simply fill out and return the sign-up form. If you are eligible to participate, we will schedule a time to come to your home to install a free Electric Water Heater Demand Response Unit (DRU). This unit, a small box installed next to your current electric water heater, will turn off the water heater automatically for up to three hours during peak demand time periods to reduce demands on the system. With the average hot water reserve capacity and insulation of today’s hot water heaters, participants in the program typically don’t ever notice that they have the unit installed.

Flathead Electric Cooperative will provide a $4 monthly participation credit for each month you are in the program. You may have one unit for each electric water heater in the location (if you have 2 water heaters and install units on both, you will get an $8 monthly credit).

With the reserve capacity of today’s well-insulated water heaters, it’s very unlikely that you’ll ever even never notice when your unit is turned off. In fact, over 1,500 units have already been installed in our service area, and we have had almost no complaints from participants about running out of hot water.

No – participation in the program is absolutely free to our members.

Flathead Electric will never turn water heaters off on the weekends (Saturday or Sunday) or on a major holiday such as Christmas Day, New Year’s Day, etc. The summer (June-September) peak demand periods typically occur weekdays between 1 and 10 PM, and the winter (October-May) weekdays between 7 and 11 AM. Water heaters are not turned off during all peak hours, in fact they are shut off an average of only twice per week, never more than once per day, and never for more than three hours.

Yes. You may have one DRU unit and monthly credit for each electric water heater in the location. For example, if you have 2 water heaters and install units on both, you will get an $8 monthly credit.

Electrical peak demand is the greatest amount of electrical power that Flathead Electric Cooperative must supply to all its customers at any given time, in any one month. During peak demand times, Flathead Electric pays higher rates. If we can lower our peak, we save money, and we pass those savings directly on to the program participants via the monthly bill credit.

Our peak demand periods typically occur during stretches of high and low temperatures (when it’s really cold in the winter and when it’s really hot in the summer). The demand for electricity during the winter is substantially greater than summer because of the need for electric heat. During the summer the largest contributor to peak demand is air conditioning. Peak times also typically happen during weekdays when members are getting ready to go to work or school.

A Demand Response Unit or DRU is a small box installed near the electric water heater. The power source for the water heater is wired into the DRU and then out to the water heater. The DRU is able to communicate with the TWACS meter currently installed at the location and respond to peak time events and predetermined schedules by turning the water heater off at the beginning of the peak demand periods and back on when it’s over.

Yes. During peak demand periods, members are encouraged to avoid discretionary use of electricity or utilize energy efficient settings when possible.

Discretionary items may include the dishwasher, the electric range and the clothes dryer. Members can use energy efficient setting such as using the air-dry mode on a dishwasher or a lower temperature setting on the clothes dryer.

In summer months members can cook on their outside grills rather than an electric range (this reduces electricity consumption for cooling because cooking indoors heats up the inside of the home).

Members can also reduce their heat temperature by 2 to 3 degrees in the winter months or raise air-conditioner settings by 2 to 3 degrees in the summer months. However, members should never adjust their heating or cooling settings to a point that could create risk to the health of members or their household.
