Geothermal Institute
Our services
Our consulting services are linked to the eight phases* of a geothermal project. The first seven cover the key development activities before the geothermal project is completed and the final phase of operation and maintenance can begin.
*The phases for geothermal development are based on The Energy Sector Management Assistance Program (ESMAP). ESMAP is a global knowledge and technical assistance program administered by the World Bank.

Phase Tasks |
Our Expertise |
1. Preliminary Survey |
|
|
2. Exploration The exploration phase consists of surface level surveys to further confirm the preliminary resource assessment. |
|
|
3. Test drilling
|
|
|
4. Project Review and Planning This phase includes the evaluation of all existing data by the developer, including new data from the exploratory phases. |
|
|
5. Field Development This phase marks the beginning of the actual development of the power project and consists of drilling production and reinjection wells, and partially constructing the pipelines to connect the wells to the plant. |
|
|
6. Construction This phase comprises installation of the steam gathering system, the separators, the power plant with the turbine, generator, and the’ cold end’. The electricity generated is sent to a substation and from there to the transmission grid. |
|
|
7. Start-up & Commissioning Start-up and commissioning of the power plant is the final phase before the plant starts regular operation. This phase usually involves resolving many technical and contractual issues with the supplier of the plant. |
|
|
8. Operation & Maintenance Operation and maintenance can be divided into the O&M for the steam field (wells, pipelines, infrastructure, etc.) and the O&M of the power plant (turbine, generator, cooling system, substation, etc.). Proper maintenance of all facilities is crucial to ensure a high availability factor and capacity. |
