The feasibility study is the second step in the decision-making process. It serves as a technical and economic decision-making tool to validate the opportunity before committing to extensive design studies and construction costs.
In France only, the ADEME-format feasibility study is conducted by Geothermaq, partnering with a partner thermal engineering firm to provide comprehensive services that integrate both underground and surface components.
In the US, the feasibilty study is conducted by Geothermaq who will be partnering with leading EPC contractors and specialized firms to provide comprehensive services that integrate both underground and surface components.
The challenge is to turn an efficiency aspiration into a viable project. Our mission is to:
Examine all regulatory requirements applicable to the project and verify that geothermal energy is permitted.
Ensure that the subsurface can provide the heating and cooling capacity required by your facilities or processes.
Analyze the various geothermal options and compare them with our recommended solution.
Estimate the total cost of ownership and calculate the actual return on investment.
Our engineers and hydrogeologists combine expertise in several areas:


At the conclusion of this project, Geothermaq will provide you with a detailed FEED report thats includes :
In France, GEOTHERMAQ, a certified expert in small-scale geothermal energy recognized by the Ministers of the Economy and Ecological Transition, is authorized to issue an opinion on GMI “orange” zones. Its OPQIBI RGE 10.07 certification guarantees recognized administrative engineering expertise, which is essential for securing grants from the Heat Fund (ADEME) and Energy Efficiency Certificates (EECs). As the primary technical point of contact for government agencies, it also provides ongoing regulatory monitoring to anticipate any changes that could impact your project.
In the US, GEOTHERMAQ USA is in the process of securing its industrial certifications.
