Geothermal Electric Power Generation
NAICS 221116 · United States · 2022 edition
This U.S. industry comprises establishments primarily engaged in operating geothermal electric power generation facilities. These facilities use heat derived from the Earth to produce electric energy. The electric energy produced in these establishments is provided to electric power transmission systems or to electric power distribution systems.
Start the review with equipment breakdown.
For Geothermal Electric Power Generation, the saved research highlights equipment breakdown, environmental liability, property. Confirm how these arise in the actual operation, what controls are used and whether additional services change the proposed coverage.
Questions to ask
- What is the total insurable value of plant structures, steam field infrastructure, and generating equipment?
- What is the chemistry of the geothermal fluids — specifically hydrogen sulfide levels, heavy metal content, or other contaminants?
- Are reinjection operations in place, and what is the regulatory compliance history for the reinjection program?
- What is the age and maintenance history of the primary turbine-generator sets?
- Are there any prior environmental incidents, regulatory notices, or well control events in the operation's history?
- For Geothermal Electric Power Generation, what should the underwriter know about prior environmental incidents, fluid spills, or regulatory enforcement actions related to the steam field or reinjection operations?
- For Geothermal Electric Power Generation, what should the underwriter know about aging well infrastructure or deferred maintenance on primary turbine and pressure systems?
- For Geothermal Electric Power Generation, what should the underwriter know about operations in seismically active areas where induced seismicity from reinjection may be a concern?

Geothermal electric power generation facilities drill into underground hydrothermal reservoirs to extract steam or hot water, which drives turbines to produce electricity. Generated power is fed into transmission or distribution grids. Operations involve continuous plant activity, steam field well management, fluid handling, and reinjection of spent geothermal fluids back into the reservoir.
