Eskom Electricity Tariffs 2025: What Are You Paying?

South Africa's electricity tariffs have risen at roughly twice the inflation rate for the past decade, making electricity one of the fastest-growing household expenses in the country. Understanding exactly what you're paying — and why — is the first step to managing and reducing your electricity costs. This guide explains Eskom's 2025 tariff structure, the history of increases, and what you can do about it.

Current Eskom Residential Tariff Rates (2025)

Note: Most South Africans are supplied by municipalities (City of Johannesburg, City of Cape Town, Tshwane, eThekwini etc.) who buy from Eskom in bulk and resell at a mark-up. Your actual rate from your municipality is typically 15–40% higher than Eskom's direct supply rate above.

Tariff Increase History (2018–2025)

South African electricity has more than doubled in real terms over the past 7 years. An average bill of R1,500/month in 2018 would cost over R3,000/month today for the same consumption. This trajectory is the core driver of the solar boom in SA.

How to Read Your Eskom or Municipal Bill

Key line items on a South African electricity bill:

• Network/capacity charge: Fixed monthly charge just for being connected to the grid, regardless of usage. R100–R500/month depending on municipality.
• Energy charge (c/kWh): The rate you pay per unit (kWh) consumed. This is what you can reduce through efficiency and solar.
• Environmental levy: Eskom charges 3.5c/kWh for the environment levy (carbon tax related).
• VAT: 15% VAT on all electricity charges.
• Reading fee / meter fee: Some municipalities charge separately for meter reading.

Time-of-Use (TOU) Tariffs vs Flat Rate

The Homeflex TOU tariff charges different rates at different times of day:

• Peak hours: 07:00–10:00 and 18:00–20:00 weekdays. Very expensive — 550–650 c/kWh.
• Standard hours: Remaining daytime hours weekdays + Saturdays. Moderate — 300–400 c/kWh.
• Off-peak hours: 22:00–06:00 and all-day Sundays/public holidays. Cheapest — 150–200 c/kWh.

TOU tariffs reward households that shift loads to off-peak times — running dishwashers, washing machines and charging vehicles at night. A smart geyser timer (R300–R800) set to off-peak hours alone can save R200–R400/month for TOU customers. Combined with solar that generates free energy during daytime peak hours, TOU customers can dramatically reduce bills.

Prepaid vs Conventional (Monthly Bill)

• Prepaid meters: Pay in advance for electricity tokens (kWh). No monthly fixed charge in most cases. Better for budget control. The first 50kWh per month is free (Indigent/FBE allocation) for qualifying households.
• Conventional (credit) meters: Billed monthly in arrears. Higher fixed charges but sometimes lower per-kWh rates for high users. Can accumulate debt if not managed.

Municipal Markups — Why Your Bill Is Higher Than Eskom's Rate

Most South Africans don't buy electricity directly from Eskom — they buy from their municipality. Municipalities purchase electricity from Eskom at bulk rates (lower than residential) and resell at a retail rate that includes their infrastructure costs and cross-subsidies. Typical municipal markups are 15–35% above the equivalent Eskom direct rate. Johannesburg residents often pay significantly more per kWh than Cape Town residents for the same consumption, due to different municipal tariff structures.
