Pros and Cons of Working as a Diesel Power Plant Maintenance Technician

How to Apply for TESDA Diesel Power Plant Maintenance Course

Just like any other job, there are pros and cons in working at a power plant. Of course, there are varying details when it comes to each specialized field, but here are the overarching benefits and setbacks:


  1. In most parts of the world, Power Plants pay lots of money. As a laborer, the base pay is $19.50 per hour. This is typically not hard work, as long as you work for at least 40 hours per week.
  2. Your coworkers are generally pleasant and humble, and they regard you as a person. There is not a dog eat dog world inside the power plant industry.
  3. There are times where workers get paid to do absolutely nothing while they’re at a plant. Operators who work in control rooms typically sit or stand at a control facility. While they are not physically hard, the repetitive tasks require constant attention. There are days when there is no job and you may sit about and do nothing. You’ve still got time on your hands. The product is created by the plant itself.
  4. There’s good hazard pay and insurance benefits. While they’re on the job, operators may be prone to suffering from electrical shock and falls. These risks can also make them more susceptible to illnesses. Still, you can rest assured that the company will provide workers compensation on top of the insurance benefits that may already be in place.
  5. In general, refinery plants pay more than chemical factories, depending on the economic condition. If the price of oil goes up, and you’re an outside operator in a refinery, your income could go up significantly.


  1. Power plants are areas with iron-clad rules. Most of these may have practical implications, such as for safety, and then there are organizational protocols, such as always keeping your shirt tucked. Moreover, utility firms are concerned about security since electricity transmission is both crucial and vulnerable to assault. Nuclear power facilities and transmission stations are particularly secure, and workers should expect to work in such surroundings.
  2. Difficult Work Hours. Since power is always needed, operators and dispatchers work rotating shifts. This means that they share the responsibilities of the less desirable hours.
  3. It’s a job that’s not for everyone, which can be a good or bad thing. Personality-wise, power plant operators are people who are realistic. They tend to be persistent, honest, and practical. They like to complete their tasks with minimal interference. Some of them are also conservative and tactile.
