Recently, consumers have shown concern about the reliability of electricity to be served. For example, some consumers need electricity with a higher reliability via automation of manufacturing processes. On the other hand, some consumers need electricity at a cheaper price even if the reliability becomes a little worse. Under such circumstances, it is necessary that power suppliers evaluate the needs of every consumer precisely and propose the most desirable measures for meeting their requirements. This paper develops a tool to analyze the reliability for high‐voltage supplied consumers quantitatively. Further, this paper presents a method for evaluating the outage cost of consumers to help them choose the most appropriate measures for maintaining reliability. The proposed method applies the fuzzy reasoning approach. The validity of the proposed method is ascertained through some numerical simulations. © 2005 Wiley Periodicals, Inc.
