Commercial Solar Wheeling Cape Town

Commercial Solar Wheeling Cape Town explains how businesses can buy electricity from private solar generators or licensed energy traders, delivered over the City of Cape Town's existing network. Compare proposals from traders, developers and advisers active in wheeling.

Wheeling solves a problem rooftop solar cannot: a business whose own roof is too small, shaded or leased can still source renewable energy generated elsewhere.

What Wheeling Is

Wheeling moves energy from a generator at one location to a buyer at another over the utility network. The utility charges for using its network, and the buyer's account is credited for the energy delivered. Physically, the electrons feed the grid near the generator; contractually, the energy is allocated to the buyer.

Wheeling In Cape Town

The City of Cape Town ran a wheeling pilot and in February 2025 announced it was opening its grid to private electricity trading between qualifying sellers and buyers. The City's published wheeling framework sets eligibility, metering, use-of-system charges and agreements, and its tariff book includes wheeling charges.

Aspect	City of Cape Town wheeling
Buyer connection	Medium or high voltage, 11 kV to 132 kV
Generator connection	Medium or high voltage
Metering	Smart metering at both ends
Charges	Use-of-system and related wheeling tariffs
Arrangements	Bilateral or through licensed traders
Agreements	Contracts with the City plus the supply agreement

Eligibility and tariffs are set by the City and change over time. Check the City's current wheeling documentation before planning.

Who Wheeling Suits

• Large businesses supplied at medium voltage with high, steady consumption.
• Companies with renewable energy targets that on-site solar cannot meet.
• Organisations with limited or unsuitable roof space.
• Multi-site businesses wanting one supply contract.
• Property owners with generation on one site and demand on another.

Small businesses on low-voltage supplies are generally not eligible under the City's current framework and are better served by rooftop solar or a PPA.

Wheeling Versus Rooftop Solar

	Rooftop solar or PPA	Wheeling
Location of generation	Your property	Elsewhere on the network
Network charges on solar energy	None for energy used on site	Use-of-system charges apply
Eligibility	Most businesses	Currently MV/HV customers
Scale	Limited by roof	Limited by contract and generator
Backup during outages	Possible with batteries	No - grid-dependent
Complexity	Moderate	High: contracts, metering, traders

Many businesses do both: rooftop solar first, wheeling for the balance.

Eskom-Supplied Customers

Customers supplied directly by Eskom follow Eskom's wheeling arrangements, and customers of other municipalities depend on whether their municipality has a wheeling framework. GreenCape publishes guidance on wheeling in the Western Cape.

Typical Steps

1. Confirm your distributor, supply voltage and eligibility.
2. Obtain 12 months or more of interval consumption data.
3. Approach licensed traders or project developers for offers.
4. Compare tariffs, contract terms, volumes and use-of-system costs.
5. Complete the City's application, metering and agreement requirements.
6. Sign supply agreements and begin wheeling once metering is live.

Commercial Solar Wheeling Cape Town Costs

Item	How it is typically priced
Energy from trader or generator	Per kWh under a supply agreement
City use-of-system and wheeling charges	Per the City's published tariff schedule
Metering upgrades	Once-off, site dependent
Advisory and contract review	R30,000 - R150,000+, scope dependent
Feasibility study	R25,000 - R100,000, scope dependent

Whether wheeling saves money depends on the difference between the delivered cost - energy plus network charges - and your current tariff. Model it using your own data before signing.

Risks To Understand

• Long contract terms and volume commitments.
• Changes to use-of-system charges during the contract.
• Generator performance and supply shortfalls.
• Credit requirements from traders.
• No resilience benefit during outages.

Frequently Asked Questions

What is electricity wheeling in Cape Town?

Buying electricity from a private generator or licensed trader and having it delivered over the City of Cape Town network, with network charges applied.

Can my business wheel solar power?

Under the City framework, buyers generally need a medium or high voltage connection (11 kV to 132 kV). Check current eligibility with the City.

Is wheeling cheaper than Eskom or City power?

It can be, depending on the energy price agreed and the wheeling charges. Model the total delivered cost against your current tariff.

Does wheeling give backup power during outages?

No. Wheeled energy relies on the grid, so it does not keep a site running during outages.

Who sells wheeled electricity?

Licensed energy traders and independent power producers with qualifying generation.

Can small businesses use wheeling?

Low-voltage customers are generally not eligible under the current City framework. Rooftop solar or a PPA is usually the route.

Can I wheel solar from my own property to another site?

Potentially, if both sites meet the connection and metering requirements and the arrangement is approved.
