Abstract Estimation of interruption costs is indispensable to determine the optimal facility investment scale and optimum reliability level at the time of distribution system planning. For this, in this paper, we calculate interruption costs by microscopic method, which reflects the pattern of power consumption by customers. For continuity with past research results, based on “Assessment of Interruption Costs on the Industry Load through Using the Microscopic Method”[1], we conducted a direct visit survey on five industries that are practically applied in NDIS(New Distribution Information System) of KEPCO: industry, commercial companies, companies and institutions, agricultural fishery products, and houses. We obtained 2,500 valid data and performed Tobit Regression based on this data to calculate domestic interruption costs in and significant data was produced when compared with the results of the interruption costs in 2008 and 2013.
