Geothermal Rebates

Washington Electric Cooperatives offers a $600 rebate on newly installed geothermal systems that meet the following requirements:

Must be ENERGY STAR - rated

Closed Loop: Minimum 17.1 EER; 3.6 COP

Open Loop: Minimum 21.1 EER; 4.1 COP

In order to qualify for this rebate, you must allow for the installation of a radio-controlled switch on the unit. The switch cycles the cooling compressor on the unit during times of peak energy demands, which are typically from 3 p.m. until 7 p.m. on only a few summer days. Essentially, the switch “shuts off” your compressor for a brief period of time. This does not control your thermostat or air handler, or harm your cooling system. It simply cycles the compressor of your cooling unit for brief periods of time. Cool air continues to circulate through your home. Cycling periods are so brief that current program participants rarely experience a change in comfort.


Radio-controlled switches must be installed on your geothermal system by the unit’s installer. Washington Electric Cooperative provides the switch at no cost, but you are responsible for the cost of having the switch installed by your geothermal contractor.

To apply or for more information, please contact our Member Services Department.
