Abstract: A computing system for predicting a curtailed consumption of fluid comprising: a module for collecting consumption data comprising information relating to an actual consumption of fluid of a plurality of consumers during a learning phase, a processing circuit for aggregating the consumption data collected by groups as a function of at least one determined descriptive variable associated with each consumer and contained in the consumption data, a processor for determining on the basis of the aggregated consumption data a curve of global load for each group, a computer for computing a model of extraction of a load curve, termed heating and/or air conditioning, on the basis of each global load curve and of meteorological data, and a predictor for computing a prediction of a curtailed consumption of fluid for each group during a forthcoming curtailment phase.
