Understanding industrial losses resulting from electric service interruptions

A comprehensive study was performed to identify the customer- and interruption-related variables that affect the customer losses. The major results pertaining to the variation of interruption costs with time of year, week, and day for small industrial electrical consumers have been reported previously by the authors (see IEEE Power App. Syst., vol.PAS-104, p.3209-15, 1985). In this paper the authors attempt to identify and describe additional factors and variables associated with the cost of interruption, such as restart time, ability to make up lost production, effect of advance warning, etc
