Efficient Electric Heating Rate

Great Lakes Energy’s Efficient Electric Heating (EEH) rate is a way for members to save on the energy used by their qualifying energy efficient electric heating system. The EEH rate offers a 3 cents per kilowatt-hour (kWh) discount for all energy used by qualifying electric ground source heat pumps (geothermal systems) 12 months per year, or air-source heat pumps for bills rendered November-May (excludes June, July, August, September and October).


The EEH rate is available to homeowners whose primary heating system is a high-efficiency ground or air-source heat pump. The homeowner must be a member of the Cooperative taking monthly service concurrently under Rate Schedules A or GS (single phase service), sign a contract, and install special equipment to begin receiving the discounted rate. (Please note: This rate became effective January 1, 2015 and replaced the Controlled Heating Rates, which are no longer available. There is no control done on your heating system under this rate.)

The requirements below are for the EEH rate and GLE rebates. Please note these standards are subject to change.

Energy Efficiency Standards

Electric heat pump must meet or exceed energy efficient standards below to qualify for EEH rate.

Type of Heat Pump EER SEER COP HSPF

Open Loop Water-to-Air Geothermal 21.1   4.1  
Closed Loop Water-to-Water Geothermal 16.1   3.1  
Open Loop Water-to-Water Geothermal 20.1   3.5  
Direct Geoexchange 16.0   3.6  
Air-Source Heat Pump Split System 12.5 15   8.5
Air-Source Heat Pump Package System 12.0 14   8.0
EER: Energy Efficiency Ratio
SEER: Seasonal Energy Efficiency Ratio
COP: Coefficient of Performance
HSPF: Heating Seasonal Performance Factor
To qualify for an Energy Optimization rebate also, your system must meet higher requirements.


How is the discount calculated?

Your electric heat pump must be wired through a subtractive auxiliary meter — this is a technical term for a second meter which only reads your heat pump electric load. It is on this meter we apply a 3 cent discount. Equipment is furnished free by Great Lakes Energy, but the installation of the subtractive meter base is the responsibility of the member. Once the meter base is installed, inspected by the county, and the heat pump is operational, the subtractive meter can be installed. The subtractive meter will record the kWh used by your electric heat pump. Your existing electric meter will continue to record the kWh use of your other home appliances at the standard residential rate. You will receive one bill for both meters. Both meters will automatically send readings to our office daily, allowing us to monitor your usage accurate and effectively.
