True, but this supports my argument about there being problems with the Eskom business model - the reason there is a winter evening maximum demand is because Eskom is charging domestic consumers the same price per kWh whenever they use it, while the true cost of providing for the maximum demand in the evening is cross-subsidised by business consumers. If the tariff was cost-reflective at time-of-use, other heating sources like LPG would be much more cost effective than electricity
