We propose an economic electricity reliability planning model which includes customer outage costs (COCs). The objective is to select transmission and distribution (T&D) planning projects which minimize the total costs of providing service in the T&D system. Total costs include both traditional...

After reviewing 16 recent studies, we 1.(i) identify the general approaches used to estimate customer outage costs,2.(ii) ascertain the relative merits of each approach, and3.(iii) determine the extent to which existing studies can provide accurate and meaningful estimates. We present cost...
