Toolbox for risk-evaluation and mitigation

Perform a thorough economic modelling of your geothermal project – with or without community funding!

How to perform an economic modelling of my geothermal project?

CROWDTHERMAL compiled the parameters necessary to perform a full economic modelling of your geothermal project. They include key project details, geological parameters, plant specifications, CAPEX, OPEX, and financing plan. The compilation is meant as a guideline for the information that is needed to create a robust financial model and perform a complete economic analysis of a geothermal project.

In addition, you can have access to a SPREADSHEET in which you may enter your own data for each parameter. Your completed, individual spreadsheet can be used as a basis for a project-specific economic assessment, financial scenario and sensitivity analyses, as well as a bankable feasibility study. From the spreadsheet, you can find additional help from experts within the CROWDTHERMAL consortium.

Reduce and mitigate the financial risks related to your project implementation!
