Several methods, indices and measures have been developed, which highlight the questions about the power systems reliability each from its specific viewpoint. The objective is to present selected reliability measures and their application related to system generation This work is focused to adequacy methods. Emphasis is placed to two groups. One group represents distribution reliability indices, where the system average interruption frequency index and system average interruption duration index are shown in theory and in practical examples through the years in selected countries in Europe. The other group represents generating power where the improved loss of load expectation is presented. Results show distribution power system reliability indices: system average interruption frequency index and system average interruption duration index, and their comparison across countries. In addition, results show improved loss of load expectation for a power system with a variety of power plants and with sensitivity cases adding the power plants to the power system or taking them out. Specially, wind versus nuclear is emphasized. Specially, the importance of reserve power is demonstrated, where wind power contribution is increasing significantly. The results show that if more wind and solar are added to the power system instead of conventional power plants, a significant quantity of reserve power needs to be added in order not to jeopardize the power system reliability.
