In the analysis of industrial energy use, detailed information on the time patterns and simultaneity of demand for energy carriers provides a basis for studying various possibilities of improving the structure of industrial energy use. This article describes the results of an investigation of the energy use patterns in six branches of industry: paper and board, meat products, dairy products, beet sugar, starch and starch derivatives, beer and malt. The results have been used to estimate the potential for cogeneration of heat and electric power in these industry branches.@en
