No fixed charge: all of your money buys units. The decision doesn’t say whether its tariffs include VAT; 15% added, as municipal tariffs are usually quoted without it. Source: NERSA decision, page 21.
Why the same R100 buys less later in the month
On this tariff, Alfred Duma sells electricity in blocks that start again on the first of every month. The first 100 kWh each month cost R2.56 a unit, VAT included, and the price goes up in steps after that, to R4.98 a unit above 650 kWh.
So R100 buys 39.1 kWh at the start of the month, but only 23.8 kWh once you’ve bought 350 kWh that month. Splitting your purchases doesn’t change this: the blocks count every unit you buy in the month, however you buy them.
