What is a Geothermal Technician?

A geothermal technician is a skilled tradesperson who works to build, maintain, and repair geothermal energy systems. Geothermal energy utilizes the natural warmth inside the earth to generate heat and electricity in a clean and sustainable way. Geothermal technicians are responsible for installing, inspecting, and servicing geothermal heat pumps and power generation stations.

The main job responsibilities of a geothermal technician include:

Installing geothermal heat pumps and connecting them to buildings’ HVAC systems

Assembling and maintaining piping systems for geothermal heat exchange
Repairing and replacing worn or malfunctioning system components
Performing preventive maintenance and routine inspections on geothermal systems

Monitoring system performance and troubleshooting issues
Advising clients on optimal geothermal system selection and placement
Ensuring compliance with codes, regulations, and safety standards

Keeping detailed records of work performed and system status

Geothermal Energy Overview

Geothermal energy is thermal energy generated and stored in the Earth. It is a clean, renewable source of energy that utilizes the Earth’s natural heat from within the crust to produce electricity and provide heating and cooling. The high temperatures found deep beneath the surface of the Earth are a result of heat from the original formation of the planet, heat produced by the radioactive decay of minerals, and heat continuously generated by the slow decay of radioactive elements found within the rock and mantle.

There are three main types of geothermal energy resources that can be utilized: hydrothermal resources, which contain hot water or steam; geopressured resources, which contain hot water or steam mixed with methane gas under high pressure; and hot dry rock, which does not have enough natural water or steam and requires water to be injected to extract heat. Each type can be used for different applications like power generation, direct heating, or geothermal heat pumps.

Geothermal energy is considered a renewable resource because the water is replenished by rainfall, and the heat is continuously produced within the Earth. The use of geothermal energy also produces very low emissions since no fuels are combusted. With proper resource management, geothermal energy can provide clean reliable power indefinitely.

Geothermal Industry Growth

The geothermal energy industry has seen steady growth over the past decade as countries around the world look to tap into this clean, renewable energy source. Geothermal energy capacity reached about 16 gigawatts globally in 2020, up from around 11 gigawatts in 2010. The geothermal market is projected to grow at a compound annual growth rate of over 5% from 2021 to 2028, reaching nearly 27 gigawatts of installed capacity by 2028.

This continued growth can be attributed to several key factors. First, geothermal energy offers a stable baseload power source, meaning it can provide constant energy output unlike intermittent sources like wind and solar. This makes geothermal power attractive for grid reliability. Second, geothermal has a small land footprint, requiring less space than solar or wind farms. Third, technological advances are making geothermal more cost-competitive with conventional power. Finally, government incentives and mandates for renewable energy are driving geothermal growth in many countries.

As more geothermal plants come online in the coming decade, there will be increased demand for skilled geothermal technicians to support site development, operation, and maintenance. The industry’s steady growth trajectory points to strong job prospects for qualified geothermal technicians.

Geothermal Technician Demand

The demand for geothermal technicians is rapidly increasing as geothermal energy continues to grow in popularity. According to the Solar Energy Industries Association (SEIA), the number of geothermal sector jobs is projected to rise 5% in 2022.

The U.S. Bureau of Labor Statistics (BLS) also predicts strong growth for geothermal technicians, estimating a 26% increase in employment from 2020 to 2030. This is over 4 times faster than the average growth rate for all occupations.

Several factors are driving the need for more geothermal technicians:

Expanding capacity of geothermal power plants and direct use installations
Retrofitting and upgrading older geothermal systems

Developing enhanced geothermal systems (EGS)
Drilling more geothermal wells and reservoirs
Constructing district heating systems and geoexchanges

Incentives for renewable energy at federal and state levels

With geothermal energy playing a greater role in the nation’s energy mix, employers will continue seeking skilled geothermal technicians to install, maintain, and repair geothermal systems.

Geothermal Technician Salary

The average salary for a geothermal technician in the United States is $52,030 per year. However, salaries can vary depending on experience, education, certifications, and location.

Entry-level geothermal technicians with less than 1 year of experience can expect to earn between $30,000 – $45,000 annually. Those with 1-4 years of experience generally make between $40,000 – $60,000. Mid-career geothermal techs with 5-9 years of experience typically earn $50,000 – $75,000 per year. The most experienced geothermal technicians with over 10 years of experience can make over $70,000 annually.

Some of the top paying states for geothermal technicians are Hawaii, California, Oregon, Idaho, and Nevada. Large metropolitan areas and states with high geothermal energy use also tend to pay higher salaries. Additionally, geothermal technicians who obtain voluntary certifications such as those offered by the International Ground Source Heat Pump Association can boost their earning potential.

Geothermal Technician Education

To become a geothermal technician, you typically need a combination of education and on-the-job training. Many employers prefer applicants who have an associate’s degree or certificate in applied science or engineering technology. Some key areas of study include heat transfer, thermodynamics, fluid mechanics, drilling technology, and geology.

Some technician training programs have cooperative arrangements with employers. This allows students to gain hands-on experience. Apprenticeship programs for geothermal technicians are also common. These programs combine paid on-the-job training with classroom instruction.

Important skills for geothermal technicians include critical thinking, problem solving, mechanical aptitude, computer literacy, and communication. Ongoing training is important as geothermal technology continues to evolve. Most geothermal companies provide their technicians with regular professional development opportunities.

With experience, geothermal technicians can advance to supervisory positions or become system designers. Some even start their own geothermal contracting businesses. Many technicians choose to remain hands-on their entire careers. Their specialized skills continue to be in high demand as the industry expands.

Geothermal Technician Job Outlook

The job outlook for geothermal technicians is very strong due to rising demand for renewable energy sources like geothermal. According to the U.S. Bureau of Labor Statistics (BLS), employment for geothermal technicians is projected to grow 24% between 2020-2030, much faster than the average for all occupations. This equates to about 1,700 new geothermal technician jobs expected to be added over the decade.

Several factors are driving the robust job growth for geothermal technicians. As climate change concerns mount and more states and utilities adopt renewable portfolio standards, the demand for clean, sustainable geothermal power is rising. Also, tax credits and other incentives are making geothermal energy more cost competitive with conventional sources. This is leading to many new geothermal power plant constructions and retrofits of existing plants, boosting the need for qualified technicians to install, maintain, and repair these systems.

In addition to strong job growth, geothermal technician roles also have a relatively low voluntary turnover rate compared to some occupations according to BLS data. This is because geothermal technicians tend to find their work meaningful given the positive environmental impact. The high job satisfaction leads to better employee retention once trained. Together with the new job creation, this results in a quite favorable outlook for those entering the geothermal technician field.
