    Work Activities
    • Identify and correct malfunctions of geothermal plant equipment, electrical systems, instrumentation, or controls.
    • Monitor and adjust operations of geothermal power plant equipment or systems.
    • Adjust power production systems to meet load and distribution demands.
    • Collect and record data associated with operating geothermal power plants or well fields.
    • Prepare and maintain logs, reports, or other documentation of work performed.
    • Install and maintain geothermal plant electrical protection equipment.
    • Maintain electrical switchgear, process controls, transmitters, gauges, and control equipment in accordance with geothermal plant procedures.
    • Maintain, calibrate, or repair plant instrumentation, control, and electronic devices in geothermal plants.
    • Determine whether emergency or auxiliary systems will be needed to keep properties heated or cooled in extreme weather conditions.
    • Test water sources for factors such as flow volume and contaminant presence.
    • Install and maintain geothermal system instrumentation or controls.
    • Prepare newly installed geothermal heat systems for operation by flushing, purging, or other actions.
    • Apply coatings or operate systems to mitigate corrosion of geothermal plant equipment or structures.
    • Operate equipment, such as excavators, backhoes, rock hammers, trench compactors, pavement saws, grout mixers or pumps, geothermal loop reels, and coil tubing units (CTU).
    • Identify equipment options, such as compressors, and make appropriate selections.
    • Install, maintain, or repair ground or water source-coupled heat pumps to heat and cool residential or commercial building air or water.
    • Perform pre- and post-installation pressure, flow, and related tests of vertical and horizontal geothermal loop piping.
    • Weld piping, such as high density polyethylene (HDPE) piping, using techniques such as butt, socket, side-wall, and electro-fusion welding.
    • Dig trenches for system piping to appropriate depths and lay piping in trenches.
    • Design and lay out geothermal heat systems according to property characteristics, heating and cooling requirements, piping and equipment requirements, applicable regulations, or other factors.
    • Integrate hot water heater systems with geothermal heat exchange systems.
    • Backfill piping trenches to protect pipes from damage.

    Abilities
    • Problem Sensitivity

      The ability to tell when something is wrong or is likely to go wrong. It does not involve solving the problem, only recognizing there is a problem.

    • Near Vision

      The ability to see details at close range (within a few feet of the observer).

    • Deductive Reasoning

      The ability to apply general rules to specific problems to produce answers that make sense.

    Knowledge
    • Mechanical

      Knowledge of machines and tools, including their designs, uses, repair, and maintenance.

    • Production and Processing

      Knowledge of raw materials, production processes, quality control, costs, and other techniques for maximizing the effective manufacture and distribution of goods.

    • Physics

      Knowledge and prediction of physical principles, laws, their interrelationships, and applications to understanding fluid, material, and atmospheric dynamics, and mechanical, electrical, atomic and sub- atomic structures and processes.
