Eskom electricity tariff—categories and rates (2023/24, c/kWh)
  • Landlight tariffs (20A and 60A), offered primarily in rural areas, are Eskom’s highest tariff rates and are exclusive to direct (non-local authority) customers.
  • The Homelight 20A Block 1 tariff, which applies to consumption between 0–350 kWh, is the lowest among Eskom’s tariffs.
  • Landlight tariffs carry higher rates because they exclude other fixed charges such as: Ancillary service charge (c/kWh), Network demand charge (c/kWh), Network capacity charge (R/POD/day), and Service charge (R/POD/day). This structure makes Landlight more suitable for rural or low-income areas, where simplifying cost recovery is necessary.
  • Eskom classifies its tariffs into the following categories:
    • Residential Tariffs (for household electricity supply): Homelight 20A, Homelight 60A, Homepower, and Homeflex
    • Urban Tariffs (for large industrial and commercial users): Megaflex, Miniflex, Nightsave Urban (Large and Small), Business Rate, Public Lighting, Transflex (rail), and Gen-Wheeling/Offset tariffs
    • Rural Tariffs (for agricultural, business, and residential customers in rural areas): Ruraflex, Nightsave Rural, Landrate, and Landlight
    • Municipal Tariffs (for municipalities purchasing in bulk and for municipal services like water pumps or offices): Municrate, Municflex, and Public Lighting.
  • Customers with rooftop solar PV systems are required to be on the Homeflex tariff plan, which is based on Time-of-Use (ToU) pricing.
  • Several Eskom tariffs are Time-of-Use-based, where charges vary depending on peak, standard, and off-peak periods. These include: Nightsave Urban Large, Nightsave Urban Small, Megaflex, Miniflex, Homeflex, Nightsave Rural, Ruraflex, and Ruraflex Gen
