Current State Policies for Geothermal Heating and Cooling

This table can help you identify which states have policies in place that apply to geothermal heating and cooling technologies, such as ground source heat pumps (GSHP) and direct-use technologies. States use a variety of policy alternatives that vary widely to support geothermal heating and cooling technology development. It is important to explore these policies when developing geothermal heating and cooling technology policy. See current federal policies. Get definitions and examples of these and other policy options.

To learn more about these state geothermal incentives, visit the Database of State Incentives for Renewables and Efficiency (DSIRE) website and search by technology.

G = Ground Source Heat Pump
D = Direct-Use
Yes = Ground Source Heat Pump and Direct-Use eligibility may vary
