Units (kWh) for each amount, VAT included. Start of month: your first units of the month, with the fixed charge paid. First buy: the month’s first purchase, if it pays the whole fixed charge before any units. After 350 kWh: once you’ve bought 350 kWh this month.

It has a fixed charge (basic charge R7.20 an amp a month, before VAT) that comes to R496.80 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, Nama Khoi sells electricity in blocks that start again on the first of every month. The first 100 kWh each month cost R2.43 a unit, VAT included, and the price goes up in steps after that, to R4.58 a unit above 250 kWh.

So R100 buys 41.1 kWh at the start of the month, but only 21.8 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

Nama Khoi charges R496.80 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 R396.80 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.
