The National Energy Regulator of South Africa (NERSA) has confirmed significant electricity law changes that will begin rolling out in September 2025. These updates will affect households, businesses, and renewable energy users across the country.
With rising costs, ongoing load-shedding concerns, and increasing demands on the national grid, these new rules aim to reshape electricity consumption, improve grid stability, and encourage renewable adoption. Every South African should understand how these changes will affect their daily lives, electricity bills, and compliance requirements.
Why These Changes Matter
These electricity law changes directly affect how much you pay and how you consume energy.
- Higher Costs During Peak Hours – If you continue using high-energy appliances (dishwashers, washing machines, geysers) during peak times, your bill could increase by up to 60%.
- Savings with Off-Peak Use – Shifting usage to off-peak hours can reduce monthly bills significantly.
- Renewable Incentives – Registered solar and renewable systems will qualify for tax incentives and rebates.
- Improved Grid Stability – These reforms aim to reduce national blackouts and the need for severe load shedding.
This is not only a compliance matter; it is about participating in South Africa’s energy transition while potentially saving money.

What Are the New Electricity Regulations?
The electricity law changes of September 2025 introduce a new regulatory framework. The most important elements include:
- Time-of-Use Tariffs
- Electricity costs will vary by time of day.
- Peak hours (mornings and evenings) will cost more.
- Off-peak hours will be cheaper, encouraging households to shift heavy usage.
- Mandatory Registration of Renewable Installations
- All solar panels, wind turbines, and backup systems must be registered, even if installed years ago.
- Failure to register could result in fines or disconnection.
- Updated Compliance Standards
- Electrical installations (especially older homes and businesses) must undergo compliance checks.
- Properties older than 10 years may need new compliance certificates.
- Load Shedding and Compensation Rules
- New framework for load shedding schedules.
- Compensation mechanisms will apply if outages exceed set thresholds.
How to Prepare for the New Regulations
To avoid higher bills and compliance issues, households and businesses should prepare now.
Practical Steps:
- Review electricity usage – Check smart meter data or request usage reports from your provider.
- Adjust appliance use – Run dishwashers, geysers, and washing machines during off-peak hours.
- Invest in timers or smart devices – Automate high-usage appliances to run during cheaper times.
- Register renewable systems – Gather documentation for solar panels and other energy solutions ahead of the mandatory registration.
- Update compliance certificates – If your electrical system is older than 10 years, schedule an inspection.
- Upgrade appliances – Energy-efficient devices may qualify for rebates under the new system.
Timeline of Implementation
- September 2025 – Launch of time-of-use tariffs and registration system for renewables.
- October–November 2025 – Municipalities phase in localized compliance measures.
- December 2025 – All households must comply with safety and installation regulations.
- Grace Period – A three-month grace period will apply for registration and compliance, but tariffs take effect immediately in September.
Real-Life Example – The Johnson Family, Cape Town
The Johnson family took part in a pilot program testing the new system. By shifting appliance use to off-peak hours (11 PM–5 AM and 10 AM–4 PM), they reduced their electricity bill by 34%.
They also registered their rooftop solar panels, which earned them a R1,200 annual tax rebate. Their experience demonstrates that adapting to the new rules can save money while supporting grid stability.
Fact Check – Electricity Law Changes September 2025

Frequently Asked Questions (FAQs)
Q1: When will the new electricity tariff system start?
A: The new time-of-use tariffs begin in September 2025.
Q2: Do I need to register my existing solar panels?
A: Yes. All renewable systems must be registered under the new NERSA rules.
Q3: What happens if I don’t comply?
A: Non-compliance could result in penalties or disconnection.
Q4: Will I pay more for electricity?
A: If you continue using electricity during peak hours, yes. But shifting to off-peak times can lower your bill.
Q5: How will this affect load shedding?
A: The new framework aims to reduce severe load shedding by encouraging balanced energy usage.
Q6: Where can I get official updates?
A: From the NERSA official site: www.nersa.org.za.
Final Thoughts
The Electricity Law Changes of September 2025 mark a turning point in South Africa’s energy management. While they may initially feel disruptive, these reforms are designed to:
- Improve national grid reliability.
- Encourage renewable energy adoption.
- Help households and businesses save money through smart energy use.
By preparing early adjusting consumption, registering renewables, and upgrading compliance South Africans can navigate the changes smoothly and even benefit financially.
