Eskom tariffs to be implemented in 2025 are adjusted with the annual increase and updates to the tariff structures as approved by the National Energy Regulator of South Africa (NERSA) on 11 March 2025. The FY2025 tariffs are adjusted with a 12.74% annual average increase and include changes to tariff structures that:

    • Simplify tariffs for low-consumption households and municipal bulk purchases. Residential Homelight customers will no longer have to pay a higher price for consumption above 350kWh and instead will pay the same cent per kilowatt-hour (c/kWh) for all their consumption.

    • More closely align to the costs of supplying electricity and support customers to pay for costs they incur resulting in a stronger user-pays principle in electricity pricing and the removal of unintended subsidies.

    • Consolidate municipal tariffs into 3 tariffs Municrate, Municflex and public lighting assisting bulk electricity purchasing

    • Increase support to the transformation of the electricity supply industry by aligning prices with NERSA-approved costs for generation, transmission (for the National Transmission Company of South Africa – NTCSA), and distribution services.

Eskom direct customers tariffs will increase by 12.74% effective on 1 April 2025 and tariffs for municipal bulk purchases will increase by 11.32% effective on 1 July 2025 as detailed in the table below.

 

The changes to tariff structures are as follows:

 Energy charges

They are unbundled from the previous all-inclusive energy c/kWh and now include separate legacy c/kWh and R/kVA generation capacity charge (GCC) charges. The decoupling of energy cost recovery into separate charges enables all to pay for the provision of capacity and simplifies the comparison to electricity generation alternatives. The only tariff that does not have this unbundled energy structure is the Homelight residential tariff.

Time of use tariffs

The ratios, prices, and periods were adjusted to better align the time-of-use signals to the National System Operator whilst meeting industry, mining and commerce needs. The ratio of peak high-demand to offpeak low-demand ratio reduced from 8:1 to 6:1. Evening peak hours increased from 2 to 3 hours whilst morning peak hours were reduced from 3 hours to 2 hours. A new 2-hour standard period on Sunday evenings was introduced.

Service charges

Large power user (LPU) tariffs service charges are now based on point of delivery (POD) and not per account.

Residential tariffs

The tariffs no longer have an inclining block structure (IBT). Homelight tariffs have a single c/kWh rate. Homepower tariffs are unbundled into separate cost reflective energy, network, and retail (service and administration) charges.

Wheeling and offset tariffs

Wheeling customers can now fairly contribute to inter-tariff subsidies from the removal of the affordability subsidy credit for wheeled energy in the Gen-Wheeling and Gen-Offset tariffs.

Transmission loss factors 

The loss factors for transmission connected customers are no longer negative and reflect the costs associated with the configuration of the network.

Municipal tariffs

Load (customer) tariffs are consolidated into 3 tariff options from the previous 10. Large power user (LPU) tariffs are consolidated into a new Municflex tariff and small power user (SPU) tariff into a new Municrate tariff.

Future tariff changes approved by the NERSA

The new Generation Capacity Charge (GCC) will be updated in FY2027 and FY2028 to implement the NERSA decision to phase it in over a three-year period. Residential fixed costs for retail will be further phased in over FY2027 and FY2028.

The comparison of the FY2026 tariffs to current tariffs may vary due to the changes in tariff structures. For example, large industry, mining, commercial, and rural customers will experience an overall reduction in fixed charges and winter energy time-of-use prices.
