Abstract
In this study we use linear mixed models to model residential electricity consumption
within the eThekwini municipal area. Utilities around South Africa are required to estimate
monthly electricity consumptions for each household within their jurisdiction however,
little work has been done to find models that may be used to do so. As part of
the modelling process we investigate seasonal trends in consumption as well as temporal
and spatial variations. Data for the study were obtained from eThekwini Electricity, a
subsidiary of eThekwini Municipality. Key findings of the research include confirming
the presence of a seasonal pattern in monthly electricity consumption and proving that
variations in consumption of different households are not related to the physical distance
between them. Models developed in this study also have applications in prediction and
may be used to predict future electricity consumption for individual households. Predictions
made using the models from this study were found to be closer to the actual value,
than that of the customary eThekwini Electricity predicted values.
