"Power engineer" redirects here. It is not to be confused with a professional engineer who specializes in power engineering.

A power engineer, also called stationary engineer, is a professional who operates industrial machinery and equipment that provide energy in various forms. Power engineers are trained in many areas, including mechanical, thermal, chemical, electrical, metallurgical, computer, and a wide range of safety skills. They typically work in factories, office buildings, hospitals, warehouses, power generation plants, industrial facilities, and residential and commercial buildings. Stationary engineering is not within the scope of Professional Engineering.

Power engineers are responsible for the safe operation and maintenance of a wide range of equipment including boilers, steam turbines, gas turbines, pumps, gas compressors, generators, motors, air conditioning systems, heat exchangers, refrigeration equipment, heat recovery steam generators (HRSGs) that may be directly (duct burners) or indirectly fired (gas turbine exhaust heat collectors), hot water generators, and refrigeration machinery in addition to its associated auxiliary equipment (air compressors, natural gas compressors, electrical switchgear, pumps, etc.).

Power engineers may hold various titles, such as boiler operator or power plant operator. In Canada, Power Engineers are ranked by classes. Fifth class being the starting point and First class being the highest level attained. This is a national standard in Canada but America isn't quite so organized in this regard. In the United States, stationary engineers must be licensed in several cities and states. The New York City Department of Buildings requires a Stationary Engineer's License to practice in the City of New York; to obtain the license one must pass a written and practical exam and have at least five years' experience working directly under a licensed stationary engineer, or three years if in possession of a Bachelor of Science degree in mechanical engineering. Holders of the Stationary Engineer's License primarily work in large power generation facilities, such as cogeneration power plants, peaking units, and large central heating and refrigeration plants (CHRPs). For the State of California, Stationary Engineers are the State of California Military Department's sole source of Airfield Lighting and Repair.

The stationary engineering trade emerged during the Industrial Revolution. The group includes railroad engineers and marine engineers. Famous people who began their working lives in this trade include George Stephenson and Henry Ford. The early steam engines developed by Thomas Savery and Thomas Newcomen which drew water from mines and the industrial steam engines perfected by James Watt and others employed the ancestors of today's engineers. Railroad engineers operated early steam locomotives and continue to operate trains today. The traditions and classification of the engineer were developed to the greatest extent by marine engineers who worked in the engine rooms of the great ocean liners in the 19th and 20th centuries. The use of the title "engineer" by Power engineers has been challenged in court by university-educated professional engineers; however, the stationary engineers have prevailed to date. The job of today's engineer has been greatly changed by computers and automation as well as the replacement of steam engines on ships and trains. Workers have adapted to the challenges of the changing job market.

Many Power engineers are becoming more involved with the technical aspect of the job as it has shifted toward a dependence on building automation. Building and central plant operations are now relying heavily on direct digital controls; and as such the engineer is required to be much more computer literate to work with the BAS (Building Automation System).
