Was an exciting job. Had to do a lot of studing on my own time.Lots of schools. Hazmat,fireschool,MSDS, Boiler School.Started and Shut-down Jet Engines.Ran all sorts of Auxillarys. Etc. Enjoyed the challenge.There were always different scenarios and had to react fast without having to ask for permission since I was in Control.Had to stay in Compliance. Started Huge Chillrs. Evrthing Huge. Our Generators generate a lot of megawatts,can not get specific. The best part was that I did most of the Black Starts For ERCOT Certification. I also learned about water chemistry. Would start Reverse Osmosis water Purification system and monitor acid introduction,and shut-down if not within parameters. I was in control of whole Plant.
