Sammendrag
In this paper we evaluate and suggest improvements to the methods that are currently in use to provide an overview of the risk to electric power systems. The currently used methods provide important decision support to investments and quality management of the sector. However, the methods are mainly concerned with ¿quality of supply¿ issues such as the number of interruptions and the amount of energy that is not supplied to the customers. We suggest a stronger emphasis on the risks related to the rare events that can have severe consequences for society. Our suggested approach to complement the current methods is based on the ¿Risk Level Project¿, which has developed a holistic framework and methodology for monitoring the risk of the Norwegian offshore petroleum activities. Instead of merely finding a set of ¿correct¿ risk indicators, the process needs to be based on a broader perspective on risk in order to provide decision support for investment, operation and maintenance of the electric power supply sector. Such a process should cover many different types of observations and indicators, and have a broad involvement by all the involved stakeholders to obtain a trustworthy, structured process where all relevant aspects are analyzed and evaluated.
