The purpose of an electrical power system is to generate electrical energy and then to transmit and distribute it through an extensive network to supply its customers with electrical energy as economically as possible and with a reasonable degree of continuity and quality. Modern society, because of its pattern of social and working habits, has come to expect that the supply should be continuously available on demand. This is possible only when the power system is reliable. So in this context the reliability evaluation of power system is very important. Reliability is old concept and a new discipline. Reliability is, and always has been, one of the major factors in planning, design, operation and maintenance of electric power system. Reliability of an electric supply system has been defined as the probability of providing the user with continuous service of satisfactory quality. This paper presents a method for generation system adequacy or reliability evaluation, which is a part of power system reliability. Generation system reliability is an important aspect in the system planning to make sure that the total installed capacity is sufficient to the consumer demand. The work is focused on the basic concepts, which can be used in the generation system reliability evaluation based on the probabilistic method by determining the reliability indices. The effect of increase and decrease in load on generation system reliability and also the effect of increase in failure rates of generating units on the system reliability are analyzed. A standard Roy Billinton Test System is used for the analysis
