Under a deregulated environment, power system operators such as utilities have to expand and reinforce the transmission network so that all participants can utilize the network equally and fairly. However, it is difficult for the power system operators to forecast how often the network will be utilized or which bus the users will connect to. Therefore, more uncertain factors exist in the transmission planning problem under a deregulated environment. This paper presents a method for evaluating the maximum power which can be injected to a bus and identifying some transmission lines which result in the bottleneck under the uncertain conditions. This paper also investigates a probabilistic load flow to consider the statistic characteristics of load change and line fault occurrence
