Why NERSA Approved New Electricity Tariffs for 2025
NERSA finalised the tariff hike to support Eskom’s operational needs, long-standing debt obligations and essential maintenance requirements. South Africa’s electricity network continues to experience breakdowns, slow repair processes and resource shortages that affect national supply. The regulator expects the higher rates to give Eskom additional financial capacity to stabilise its generation and distribution systems. Many consumers, however, feel that they are unfairly absorbing the cost of Eskom’s management failures and the continuous decline in service reliability.
Detailed Breakdown of the December 2025 Electricity Price Increase
The approved tariff increase will raise electricity bills by an average of 12 percent nationwide. Depending on the region, some municipalities may apply further adjustments once the national tariff takes effect. Households are expected to see their monthly expenses rise between R150 and R300, depending on how much electricity they use each month. Businesses that rely heavily on machinery, refrigeration or industrial equipment will face larger increases, which could eventually lead to higher prices for products and services across the country.
Impact of the Tariff Hike on Homes and Small Businesses
Families already paying more for groceries, transport and essential services may face difficulty managing the additional rise in electricity fees. Many households will need to reduce overall spending or change their energy habits to stay within budget. Small and medium-sized enterprises may also struggle to absorb the new operational costs. These businesses often operate with limited profit margins, and higher tariffs may force them to raise their prices or cut back on staff and services, affecting local communities and the broader economy.
Practical Ways to Manage Rising Power Costs
There are several steps consumers can take to reduce the impact of higher electricity prices. Switching to energy-efficient appliances and LED lighting can help lower monthly consumption. Households should also use high-energy devices like geysers, heaters and stoves more strategically to avoid unnecessary spending. Exploring alternative energy options, including solar systems or hybrid power setups, may also offer long-term savings. Simple changes to daily energy habits can significantly reduce the effect of increased tariffs.
Final Verdict
The December 2025 electricity tariff hike marks another adjustment that will place added pressure on households and businesses already dealing with rising living costs. While NERSA believes the increase is necessary to strengthen South Africa’s electricity infrastructure, consumers will inevitably carry the financial impact. Preparing early, monitoring energy usage and exploring cost-saving options will help South Africans navigate the change more effectively.
