The National Energy Regulator of South Africa (NERSA) has published Eskom’s proposed Retail Tariff Plan for public consultation detailing changes to its tariff charges and rates. The primary goal is to ensure that customers only pay for the costs they incur.
The proposed tariff changes aim to support an evolving electricity supply industry, ensuring that electricity tariffs reflect NERSA-approved costs for generation, transmission, and distribution services, while considering affordability, fairness, and transparency.
“The electricity supply industry is undergoing fundamental changes that will set the course for economic growth and prosperity in the years ahead. It is therefore vital that as many stakeholders as possible engage with NERSA on the proposed changes to support the determination of tariffs that are as fair as possible for all customers,” said Monde Bala, Eskom Group Executive for Distribution.
“The proposed tariff changes aim to restructure existing tariffs and avoid the creation of unintended subsidies. It is important to note that the tariff restructuring process is separate from Eskom’s current revenue application to NERSA for the 2025 to 2028 period under the MYPD 6 process. Eskom will not generate additional revenue from the proposed tariff restructuring but will rebalance the charges while remaining within the 2024/25 costs already approved by NERSA,” concluded Bala.
This application follows similar submissions made to NERSA in 2020 and 2022. However, except for the introduction of the Homeflex tariff, a residential tariff that enables grid connection and energy export for solar Photovoltaic (PV) customers in 2022, none of the previous submissions were approved.
Major structural changes proposed by Eskom to the retail tariffs include:
• Currently, residential households on prepaid and post-paid pay more per unit as they buy more electricity during the month, due to the inclining block tariff (IBT). Eskom is proposing to remove the IBT so that low-usage households pay the same price no matter how many times electricity is bought in a single month to support affordability and provide greater access to energy services.
• Customers with solar rooftop PV connected to the grid who use Eskom-supplied energy as a backup, known as the “Eskom battery” on cloudy days, at night and during the morning and evening peak will still be required to pay for using the Eskom network.
• Customers with the technology to export any own-generated excess energy onto the grid can further reduce their electricity bill through energy credits to their electricity bills.
• Tariffs for municipal distributors purchasing in bulk are likely to benefit on average from lower costs due to lower subsidy contributions and reduced fixed charges through consolidating their 15 tariffs into three options.
• Large industry, mining, commercial and rural customers will see an overall reduction in fixed charges and winter energy time-of-use prices. Services charges for large industry, mining and commercial users that consume significant quantities of baseload power will in future be calculated on each point of supply, which ensures fairness and better reflects the resources required to manage multiple Points Of electricity Delivery (POD) at large industrial and mining sites.
The application does not include customers who have completely disconnected from Eskom’s grid and have no Eskom connection or meter.
Unbundled tariffs will enable Eskom to recover NERSA-approved costs and returns by aligning prices and tariff rates with the actual costs incurred. Insufficiently unbundled tariffs pose revenue risks for the licensee and unfairly increase tariffs for all customers. Properly unbundling and structuring tariffs will ensure fair cost recovery, avoid unfair cross-subsidies, and support the responsible integration of alternative energy sources.
This application is a crucial step towards fully unbundled tariffs, which will have separate charges for electricity capacity usage and network services. This approach will accurately reflect the costs of providing electricity services and enhance transparency for customers.
