Power plants are not functioning to the fullest 100 % of the time. Maintenance and inspection of some components require them to be off-line in time, however, this can be planned such that customers continue receiving power from the electrical grid, steam or district heating from other plants. Unplanned outages due to failures or external conditions may cause surprises and can lead to situations in which the demand is not satisfied at short term at large costs.

In this book unavailability is modelled both qualitatively and quantitatively, in order to optimize power plants efficiency.

The book is derived from earlier papers presented at ESReDA, PGMON, VGB working groups and other committees while the author was working with KEMA and its legacy companies and departments NRG, DNV GL and DEKRA.
