GeothermEx is the most comprehensive geothermal resource consulting and services firm in the Western Hemisphere. Having served a large and diverse client base in evaluating and developing hundreds of geothermal fields, we specialize in the riskiest part of any geothermal project: the resource itself. For almost 40 years, our geoscientists and engineers have solved resource-related issues for geothermal projects in more than 50 countries, providing unparalleled insight, quality, efficiency and results. Using an interdisciplinary methodology that has generated proven results since 1973, our comprehensive suite of services covers the full spectrum of resource-related issues: from exploration and drilling through analysis, project management, financial modeling and operational support. GeothermEx's work has led to the successful installation of 7,000 MW of geothermal power and has enabled more than $11 billion in project financing. We have worked with nearly every energy company involved in geothermal exploration and development, and with public and private electrical utilities and financial organizations, government agencies and land owners in executing geothermal energy projects. We also work closely with engineering companies that design and construct geothermal power plants so that maximum efficiency and sustainability is achieved from every bit of the geothermal fluid extracted from deep underground.
