It has a fixed charge (capacity charge R4.51 an amp per phase a month, before VAT) that comes to R311.18 for November, with VAT, on a 60 A single-phase supply. 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.

Why the same R100 buys less later in the month

On this tariff, Sol Plaatje sells electricity in blocks that start again on the first of every month. The first 350 kWh each month cost R3.18 a unit, VAT included, and R3.60 a unit above 350 kWh.

So R100 buys 31.5 kWh at the start of the month, but only 27.8 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.

The fixed charge

Sol Plaatje charges R311.18 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 R211.18 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.
