Generalization of Netback Value Calculations for the Determination of IndustrialDemand for Natural Gas

摘要

When a new fuel is introduced in a large geographical area with many differentindustries, methods for demand assessment based on the netback value for individual consumers can not be applied. The energy demand forecasts that result from economic models, are not detailed enough to be of any help either. A solution is the formulation of production processes that cover the total energy demand by the manufacturing sector, provided that these processes can be regarded as representative processes. For these production processes the netback value analysis can be applied. Two problems have to be solved: (1) how can a minimal set of production processes be formulated; and (2) how can they be linked to national statistics data based on the International Standard for Industrial Classification of economic activities. For both problems a solution is formulated, and this solution is applied to the manufacturing sector of Java in Indonesia.
