It has a fixed charge (basic charge R134.81 a month, before VAT) that comes to R155.03 for November, with VAT. You pay it whatever you use, and your prepaid purchases pay it first. The decision doesn’t say whether its tariffs include VAT; 15% added, as municipal tariffs are usually quoted without it. Source: NERSA decision, page 19.
Why the same R100 buys less later in the month
On this tariff, Rand West City sells electricity in blocks that start again on the first of every month. The first 50 kWh each month cost R2.41 a unit, VAT included, and the price goes up in steps after that, to R5.07 a unit above 600 kWh.
So R100 buys 41.5 kWh at the start of the month, but only 23.0 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.
The fixed charge
Rand West City charges R155.03 a month on this tariff, VAT included, whatever you use, and your prepaid purchases pay it first. If the whole month’s charge comes off your first purchase, your first R100 of the month buys no units at all, and R55.03 of the charge is still owed from your next purchase. Municipalities collect it in different ways, some a little with every purchase. Your till slip shows what was taken.
