The added value of reliability analysis for power system planning is illustrated. The increased cost pressure given by the open market activities lead to the necessity to extend the classical planning tools by reliability analysis. Modern reliability analysis tools allow a detailed analysis of the results after calculating the reliability indices. Besides overall values for the power system, the results for different load nodes can by analyzed individually. This includes the important information of which outage and of which component in the system is mainly responsible for supply interruptions of the investigated node. Based on this information, weak points in the system can be detected and improvement measures taken. In conclusion, it can be stated that reliability analysis is a powerful tool in addressing the requirements of the new market.
