Why the same R100 buys less later in the month
On this tariff, Ulundi sells electricity in blocks that start again on the first of every month. The first 600 kWh each month cost R3.42 a unit, VAT included, and R4.87 a unit above 600 kWh.
So R100 buys 29.2 kWh at the start of the month, but only 20.5 kWh once you’ve bought 600 kWh that month. Splitting your purchases doesn’t change this: the blocks count every unit you buy in the month, however you buy them.
Ulundi charges more in winter (June to August): then R100 buys 22.8 kWh at the start of the month.
