Every geothermal project has uncertainties, particularly at the early stages of development. Even during later stages, the most significant variable in any geothermal project is the resource itself. Assessing resource risks and opportunities is crucial to long-term success.
When government agencies and financial institutions need independent third-party assessments of the capacity, sustainability, and value of geothermal resources, many come to us for
