Abstract

The previous chapter illustrates the application of basic probability methods to the evaluation of static capacity adequacy. The basic indices illustrated in Chapter 2 are the expected number of days (or hours) in a given period that the load exceeded the available capacity and the expected energy not supplied in the period due to insufficient installed capacity. These are useful indices which can be used to compare the adequacy of alternative configurations and expansions. They do not, however, give any indication of the frequency of occurrence of an insufficient capacity condition, nor the duration for which it is likely to exist. The LOLE index of days/year, when inverted to provide years/day, is often misinterpreted as a frequency index. It should, however, be regarded in its basic form as the expected number of days/year that the load exceeds the available installed capacity.
