NERSA & Solar Wheeling — questions
Frequently asked questions about NERSA registration and solar wheeling
Since the 2021 amendment to Schedule 2 of the Electricity Regulation Act, most embedded generation no longer needs a generation licence, but registration with NERSA is still required, and wheeling always needs a use-of-system agreement with the network operator carrying the electricity.
Do I need a NERSA licence for rooftop solar?
Most rooftop and embedded solar installations no longer need a generation licence because of the 2021 amendment to Schedule 2 of the Electricity Regulation Act. Registration with NERSA is still required in almost all cases.
Is there still a capacity limit for licence-free generation?
No fixed capacity threshold applies any longer for the licensing exemption itself, but the exemption conditions in Schedule 2, including how the electricity is sold, must still be met regardless of size.
What is the difference between registration and a generation licence?
Registration is a lighter administrative process for generators that meet the Schedule 2 exemption conditions. A generation licence is a formal NERSA authorisation required for projects selling to multiple customers outside a trading licence structure.
Can I wheel electricity to a site in a different municipality?
Yes, provided you conclude use-of-system agreements with every network operator whose infrastructure carries the electricity, which may include both Eskom and one or more municipalities.
Do municipalities all charge the same wheeling tariff?
No. Each licensed municipal distributor sets its own wheeling tariff and connection rules, approved through its own tariff process, so rates and conditions differ between metros.
Do I need a trading licence to sell solar power to my tenants?
If you are selling to a single customer or supplying your own site, registration is normally enough. Selling to multiple separate customers directly, without a licensed trader, generally requires a trading licence.
How long does NERSA registration take?
A complete registration submission for a straightforward embedded generator is typically processed within four to eight weeks, though network connection studies can extend the overall project timeline.
What happens if I generate and wheel without registering?
Operating without the required registration or licence is a contravention of the Electricity Regulation Act and can result in enforcement action by NERSA, and it also makes the network operator unlikely to conclude a connection or use-of-system agreement.
Does an environmental authorisation apply to solar projects?
Certain solar facilities trigger environmental authorisation requirements under the National Environmental Management Act depending on size and location, and this should be confirmed before finalising the NERSA submission.
