In this paper, we estimate the price elasticity of electricity for various industrial sectors of the South
African economy from 2002 to 2011. The data used include sectoral electricity consumption data and
electricity tariff data, both courtesy of Eskom as well as output data based on national statistics. The most
important contribution this paper makes is that it includes the period after the sharp rises in electricity
tariffs in 2007/2008 following a period of load-shedding and insecurity in electricity supply. Previous studies
have included data only until 2007 and, for the most part, have found statistically insignificant, positive
elasticities. However, for the period post-2007, we found statistically significant and negative elasticities for
9 of the 11 sectors considered. Our results show that the majority of industrial sectors have become much
more sensitive to changes in the price of electricity following 2007/2008, indicating to policymakers that
tariff restructuring might influence consumer behaviour significantly.

The impact on demand resulting from an electricity price increase is unknown, Dekenah, Heunis, Gaunt and Cheek (2003). This study focused on large Eskom customers (industry and mining) and the impact of increased electricity ...
