Career summary

Geothermal technicians install and repair geothermal heating and cooling systems.

Geothermal power uses heat generated by the Earth's core to provide energy. In geothermal plants steam and hot water is used to generate electricity.

Geothermal technicians install, maintain, and repair geothermal systems at power plants and other sites. Technicians inspect and test specific sites to determine the amount of heat available. They check the water for flow strength and for toxic materials. They decide on the best system and equipment to provide heating and cooling.

After installation, technicians test the system by filling and draining the system with water. They make sure that all controls, switches, gauges, and transmitters are working properly.

After installation is complete, technicians test, troubleshoot, and maintain instruments and controls. They also calibrate and repair equipment when necessary.

During operation, technicians monitor instruments and gauges to be sure the plant is working correctly. They make adjustments as needed. They keep logs of maintenance and repairs. To prevent corrosion, technicians regularly apply sealants to geothermal equipment and structures.

Since the heat emitted from the earth changes, technicians collect data to spot trends. This helps maintain consistent power production.

Training

To work as a geothermal technician, you typically need to:

Education after high school

Training to work as a geothermal technician is much the same as training to become a heating and cooling system mechanic. Even though geothermal systems are unique, in that they use heat from below the earth's surface, using air to heat and cool a home involves a similar set of skills to those involved in HVAC (heating, ventilation, and air conditioning).

As this occupation grows, programs that focus specifically on geothermal energy as opposed to HVAC will be offered. For now, geothermal technicians may complete a formal training program in heating, air conditioning, and refrigeration technology. Professional-technical schools or two-year colleges offer these programs. They grant a certificate or associate degree. In these programs you learn to read schematic drawings, analyze problems, and follow safety procedures. You also learn to determine whether to replace or repair parts.

On-the-job training

After completing a training program, most geothermal technicians learn additional skills on the job from an experienced worker. You begin as a helper and do basic tasks. As you gain experience you work on more difficult tasks. Training includes:

Training may last up to one year.

Helpful high school courses

You should take a general high school curriculum that meets the state's graduation requirements (external link). You will be required to take both math and science classes to graduate. You should consider taking Algebra and Geometry as your math courses and Chemistry and Physics as your science courses.

Helpful electives to take in high school that prepare you for this career include:

The courses listed above are meant to help you create your high school plan. If you have not already done so, talk to a school counselor or parent about the courses you are considering taking.

You should also check with a teacher or counselor to see if work-based learning opportunities are available in your school and community. These might include field trips, job shadowing, internships, and actual work experience. The goal of these activities is to help you connect your school experiences with real-life work.

Join some groups, try some hobbies, or volunteer with an organization that interests you. By participating in activities you can have fun, make new friends, and learn about yourself. Maybe one of them will help direct you to a future career. Here are examples of activities and groups (PDF file) that may be available in your high school or community.

Things to know

Employers prefer to hire technicians with training in heating and cooling systems or specifically in geothermal technology. As more individuals become aware of the benefits of using geothermal energy, more programs will be offered in this field.

Employers also prefer technicians with both hands-on and mathematical skills.

Costs to workers

Union workers pay an initiation fee and regular membership dues. Workers may also need to buy work clothing and footwear. Some workers may be required to supply their own tools.

Licensing/certification

Typically, workers who install, test, and maintain electrical systems are required to have an electrician's license. Check with your state for information about local licensing requirements.

Wages

Pay varies with the worker's level of education, responsibility, and experience. Salaries vary greatly by employer and plant size. Pay also varies depending on the employer and the area of the country.

Geothermal technicians who work full time usually receive benefits. Typical benefits include sick leave, paid vacation, health insurance, and a retirement plan. 

National wage information is not available specifically for geothermal technicians. However, they are part of the larger group of "all other installation, maintenance, and repair workers."

Employment and outlook

Washington outlook

Currently, there is no specific statewide outlook information available for geothermal technicians.

Nine western states have operational geothermal generation plants.  At this time there are no plants operating or planned for construction in Washington State.

National employment

Major employers:

National outlook

Demand for this occupation will be steady. The US is interested in reducing foreign oil imports and developing resources such as geothermal energy systems. Technicians will be needed to install and repair these systems.

Job prospects will be best for those with experience and skills.
