What R50 to R1,000 buys in Bloemfontein (Centlec)
Tariff II: IBT Domestic (conventional and prepaid)28.6 kWhfor R100 at the start of the month, plus a fixed R57.50 a month
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.
| You pay | Start of month | First buy | After 350 kWh |
|---|---|---|---|
| R50 | 14.3 | 0.0 | 12.4 |
| R100 | 28.6 | 12.1 | 24.8 |
| R200 | 57.1 | 40.7 | 49.6 |
| R300 | 85.7 | 69.3 | 74.4 |
| R500 | 142.8 | 126.4 | 124.0 |
| R1,000 | 285.6 | 269.2 | 248.0 |
| Units this month | Price a unit | R100 buys |
|---|---|---|
| First 350 kWh | R3.50 | 28.6 kWh |
| Above 350 kWh | R4.03 | 24.8 kWh |
It has a fixed charge (basic charge R50.00 a month, before VAT) that comes to R57.50 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 21.
Why the same R100 buys less later in the month
On this tariff, Centlec (Mangaung) sells electricity in blocks that start again on the first of every month. The first 350 kWh each month cost R3.50 a unit, VAT included, and R4.03 a unit above 350 kWh.
So R100 buys 28.6 kWh at the start of the month, but only 24.8 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
Centlec (Mangaung) charges R57.50 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 12.1 kWh. Municipalities collect it in different ways, some a little with every purchase. Your till slip shows what was taken.
Centlec (Mangaung) charges more in winter (June to August): then R100 buys 23.1 kWh at the start of the month.
