There are state incentives available through Wisconsin's Focus on Energy program or your local utility. See the Focus on Energy website for their incentives.
Federal incentives are available in the form of tax credits. They are available for both residential and commercial systems.
The residential tax credit is for 30% of the cost of a system, with no maximum. More information on this tax credit can be found at the following link: Residential Renewable Energy Tax Credit
The commercial tax credit is for 10% of the cost of a system, with no maximum. More information on this tax credit can be found at the following link: Corporate Renewable Energy Tax Credit
Geothermal systems cost more than conventional systems due to the cost of installing the ground loop (or pond loop). However, the life-cycle cost of a geothermal system is competitive with conventional systems due to energy savings over the life of the system. For more specific costs, consult a WGA member in your area.
The U.S. Department of Energy explains:
These ENERGY STAR® efficiencies compare favorably to a COP of 1.0 for resistance heaters and an EER of 10.0-11.0 for central air conditioners.
Geothermal systems generally pay for themselves in 7-12 years through savings in energy cost.
All members of the WGA must pay a yearly fee, accept and agree to the Code of Ethics and meet the characteristics described below.
