In fast growing electricity networks such as the one in Turkey, it is vital for long term investment plans to be done after careful investigation of the existing system situation. As an investment indicator, in this paper, Thermal Security Index (TSI) method is applied to the data of expected Turkish Grid system 2013 Summer Peak including the load flow solutions of the outages of the 400 kV and 154 kV transmission lines and the 400 / 154 kV autotransformers, resulting in total number of 1867 contingencies. For each contingency, the effect of the outage on the other elements are monitored, accumulated, and ranked according to its TSI. In addition, to gain insight about the regional problems of the network, for each region in Turkey, the average effect of an outage is calculated which is directly related with the undesirable load shedding values for both network operator and citizens. As a result, a very useful indicator for determining the future investments plans for transmission system is presented.
