Power-Plant Reliability, Availability, Maintainability

If a boiler is shut down for cleaning and inspection, it cannot generate steam. It may be extremely reliable, but it is unavailable the week it is shut down. With a power plant providing a utility typically required continuously, availability—the probability of functionality when required—is the most important trait of a power plant.
