Is electricity cheaper in Zimbabwe or South Africa?

Electricity is a major household expense across Southern Africa, but the amount consumers pay for the same amount of power can differ significantly between countries.

So, how much would it cost a household to buy 400 units of electricity in Zimbabwe and South Africa?

For this comparison, 400 units means 400 kilowatt-hours (kWh).

In Zimbabwe, the calculation uses the current ZESA/ZETDC residential prepaid tariff.

In South Africa, the comparison uses Eskom’s Homelight 60A residential tariff, which is a flat-rate prepaid tariff.

Municipal electricity tariffs can differ.

How much does 400 units of electricity cost in Zimbabwe?

Zimbabwe’s electricity tariffs are structured in consumption bands, meaning the price per unit increases as a household uses more electricity.

The Zimbabwe Energy Regulatory Authority (ZERA) currently lists the first 50 units at US$4.24, including the applicable rural electrification levy.

Current August 2026 ZESA tariff data puts the cost of buying 400 units at about US$77.03 (about R1 227), or approximately ZWG1,973.94 at the displayed exchange rate.

This means a Zimbabwean household buying 400 units would spend roughly US$77 (R1 227).

The stepped structure is important because the household does not pay the highest rate for all 400 units.

The first units are charged at lower rates, with the price increasing through the consumption bands.

How much does 400 units of electricity cost in South Africa?

South Africa has several electricity tariff structures, depending on whether a household receives electricity directly from Eskom or through a municipality.

For this comparison, Eskom’s Homelight 60A tariff provides a straightforward benchmark. Eskom’s 2026/27 tariff schedule sets the Homelight 60A energy charge at 343.61 cents per kWh, including VAT.

At that rate, 400 units would cost:

400 × R3.4361 = R1 374.44

So, under Eskom’s Homelight 60A tariff, 400 units cost approximately R1 374.

Eskom describes Homelight 60A as a tariff for medium- to higher-consuming residential supplies, with a single cents-per-kWh energy charge.

Zimbabwe vs South Africa: Which is cheaper?

Using the current exchange rate of about R15.93 to US$1 on 26 August 2026, Zimbabwe’s US$77.03 cost works out to approximately R1 227.

That gives the following comparison:

	Zimbabwe	South Africa
Electricity	400 units	400 units
Equivalent	400 kWh	400 kWh
Utility/tariff	ZESA/ZETDC	Eskom Homelight 60A
Cost	~US$77.03	R1 374.44
Converted to rand	~R1 227	R1 374.44

On this comparison, 400 units of electricity are cheaper in Zimbabwe, by roughly R147 at the 26 August 2026 exchange rate.

However, the difference is relatively small and can change as the rand moves against the US dollar.

The South African tariff you pay may be different

The comparison does not mean every South African household pays R1,374 for 400 units.

Eskom has several residential tariffs, including Homelight, Homepower and Homeflex.

In addition, many South African households receive electricity from municipalities rather than directly from Eskom. Municipalities set their own approved tariffs, meaning the cost of 400 units can vary depending on where the household lives.

For example, Johannesburg’s City Power and Tshwane have different residential tariff structures from Eskom’s Homelight tariff.

Therefore, the R1 374 figure should be treated as an Eskom benchmark rather than the price every South African household will pay.
