Maintenance comprises i.a. repair, inspection and overhaul. There is not the one and only maintenance strategy for each and every power plant operator. The best strategy might differ from case to case and a blend of different concepts might be the optimum. Be it preventive, reactive or predictive – many factors are to be considered. It’s important to first of all agree on the target.


Example: Maintenance interval

Hydro turbines are patient. An extended maintenance interval usually will not lead to a short term failure increase. But long term consequences might be severe.

By the way: Conflicts of interest cannot be avoided. Safety, profitability and plant reliability are just a few examples.
