Energy management for rational electricity use [cement plant]

A description is given of an energy management system whose goals are energy cost reduction and reduction of specific energy consumption. The basic system concept is composed of three distinct, but closely interrelated management tasks which are supported by software and hardware information systems. The ELCON (electric load control) module keeps track of usage online and indicates where and when corrective measures are necessary. This can be accomplished through automatic load switching or through preparation of instructions for manual intervention by the control room operator. Computerized energy data collection is the crucial point and a precondition for the second step goal: reduced specific energy consumption. It is shown that an energy cost reduction of between 3 to 6% may be expected
