South African households and businesses are bracing for another increase in energy costs as municipal electricity tariffs rise in July, threatening to add pressure on consumers despite expectations of relief from lower fuel prices.
Data from the Central Energy Fund (CEF) shows petrol price over-recoveries of between R2.93 ($0.16) and R2.97 (US$0.16) per litre for 95 and 93 unleaded petrol respectively, while diesel has recorded over-recoveries ranging from R4.60 (US$0.25) to R5.02 (US$0.28) per litre.
A reduction in fuel prices is expected to provide some relief, but analysts warn the benefit could be short-lived as higher electricity costs take effect.
South Africa’s state power utility Eskom implemented an average tariff increase of 8.76% for direct customers from April 1 as part of its approved 2026/27 pricing structure.
Municipal electricity users will face a further 9.01% increase from July 1, adding to rising operating costs for households and companies.

SolarAfrica CEO David MacDonald said a typical commercial and industrial business using about 1 million kilowatt-hours of electricity per month could see annual electricity costs rise by between R2.88 million (US$158,000) and R3.34 million (US$183,000), depending on consumption patterns.
The increase translates into an additional monthly burden of between R240,000 ($13,000) and R280,000 (US$15,000) for affected businesses.
MacDonald warned that rising electricity prices were becoming a structural challenge rather than a temporary shock, with another 8.83 percent increase already proposed for the following year.

The continued escalation is making long-term planning difficult for energy-intensive industries such as manufacturing, mining, agriculture and logistics, where electricity represents a significant share of operating expenses.
Energy efficiency measures are increasingly being promoted as a way for businesses and households to manage rising costs.
Trevor Brewer, director at Solenco, said consumers should view energy management as an ongoing financial discipline rather than a once-off investment.
He advised households and businesses to assess appliance wattage, energy ratings and inverter compatibility when purchasing equipment, while prioritising appliances with eco modes, timers and efficient motor technology.
Brewer also urged consumers to ensure appliances are appropriately sized for their needs to reduce unnecessary energy consumption.
The tariff increases come as South Africans continue to deal with higher living costs, with electricity and fuel among major expenses affecting household budgets and business competitiveness
