Second-Class Power Engineer / Stationary Power Engineer License:



A Second-Class Stationary Power Engineer is intended for a non-supervisory role in the power plant or generating facility in the role of a Group Leader

The fees for the Second-Class Stationary Power Engineer are listed in the license application, and engineers can apply for a reciprocal license, which is based on experience and holding a license from recognized State, Municipal, Federal and Third-Party licensing entities.

Reciprocal License Note: Jurisdictions that have a Stationary Engineer's or Stationary Operating Engineer's license does not ensure a Stationary Power Engineer license will be issued. An example: A jurisdictional license-holder has a stationary engineer's license and has experience operating a high-pressure boiler plant, but has no experience operating a steam-turbine generator does not qualify, but will qualify for one of NASOE's High-Pressure Boiler Engineer's Licenses.

The qualification to sit for examination are the individual must have 12-months in a high-pressure plant that has steam turbine generators and have a Basic Electricity diploma or training certificate or two-year technical or science degree (college) with 6-months in a high-pressure plant that has steam turbine generators. Or, hold a 3rd Class Power Engineers license from National (NASOE) for 6-months.

The exam is based on what a Group Leader (2nd Class) should know or have knowledge to recognize, comprehend and explain power plant conditions. The examination is a 75-Question test in a 2-hour period. Math formula references will be included in the exam packet. The components of the exam is made up of the following:
