Tap Into Earth to Heat and Cool Your Home

Save Money
As you Save the Earth
Geothermal systems not only give home and business owners the satisfaction of doing their part in building a cleaner energy future, they also save them money on heating and cooling costs every month, rain or shine.
Economical
Everyday, geothermal systems save home and business owners 30 to 60 percent on their heating or cooling costs.
Environmentally Friendly
No fuel, no emissions. Take advantage of the organic energy stored in the earth.

Value
Not only does a geothermal system assist with heating and cooling, it also contributes to water heating.

Efficient
Geothermal systems are as much as four times more efficient than conventional systems.

Geothermal Cooling
As outdoor temperatures rise, a geothermal heat pump collects the unwanted heat in your home or business and moves it to the cooler earth, while collecting the cooler underground air and distributing it throughout the home or business. Conventional heat pumps and air conditioners exhaust that heat outside, causing conventional cooling systems to work harder and less efficiently.


Geothermal Heating
As outdoor temperatures fall, a geothermal heat pump draws air from below the earth’s surface where temps are consistently 55-60 degrees, condenses the heat to raise the temperature, and then moves it throughout your home or business. Conventional heat pumps collect heat from frigid winter air, making them less efficient. Unlike a furnace, geothermal units don’t create heat through combustion. They simply collect the heat and move it.

Geothermal Energy Rate

DTE Energy supports the adoption of geothermal systems with a special geothermal rate option. This rate is structured as a time of day rate with different pricing in the summer than in the winter. This geothermal rate option could save you approximately 50 percent off the standard DTE Energy residential electric service rate.
 

Items Measured on the Geothermal Meter
Your Geothermal Rate will be applied for energy used by your geothermal unit, fans, Electronically Commutated Motor (ECM) blower motors, electric water heater, electric resistance heat and well pump (open loop geothermal system only).
 

To qualify and enroll for the Geothermal Rate
Residential and business customers must meet the following requirements to qualify for the geothermal rate.

To enroll:

  • Contact one of our service planners before you start. Your DTE Energy expert will check to see if your existing electrical equipment can handle the extra load, allowing you to build your geothermal system for maximum returns.
  • Have wiring installed by a licensed, independent electrical contractor to accommodate a separate geothermal advanced meter.
  • Contact DTE Energy Customer Service at 800.477.4747 to request installation of the meter once the wiring is completed. Refer to the D 1.7 meter and rate code 036 when speaking to your customer representative.
