South Africa’s CHARGE rolls out off-grid solar EV stations on key highway

South Africa’s electric vehicle infrastructure rollout is gaining ground along one of its most important freight routes, as private developers move to work around persistent limits in the country’s electricity system.

The latest step comes from Zero Carbon Charge (CHARGE), which has begun deploying off-grid, solar-powered EV charging stations on the Johannesburg-to-Durban N3 corridor. 

The initiative highlights a practical shift in how EV infrastructure is being built in South Africa.

Instead of relying on the national grid, developers are increasingly opting for independent energy systems that can function outside Eskom’s constrained supply network. 

The N3 corridor links Gauteng’s industrial base with the Port of Durban, handling a large share of the country’s freight movement.

Its role in trade and logistics makes it a key early testing ground for electric mobility infrastructure. 

At the same time, South Africa’s power challenges continue to shape investment decisions.

Load constraints, ageing infrastructure and rising electricity costs remain key barriers to scaling EV adoption nationwide.

Off-grid charging model expands 

Zero Carbon Charge (CHARGE) said the new stations are fully off-grid, powered by solar energy paired with battery storage systems.

The model is designed to reduce dependence on Eskom, which continues to face operational strain and recurring supply disruptions. 

The company says the approach is intended to provide more reliable charging availability along long-distance routes.

It also reflects a broader move toward self-sufficient energy systems in transport infrastructure planning.

EV demand shows early growth 

Despite a relatively small base, interest in electric vehicles is rising.

AutoTrader data shows EV-related searches in South Africa increased 45% year on year between February and March 2026, while engagement climbed more than 200%. 

Industry body naamsa reports new energy vehicle sales rose 7.1% to 16,716 units in 2025, following a sharp increase the year before.

However, EVs still represent only 2.8% of total new vehicle sales, underscoring the early stage of market development.

Expansion plans target national network 

CHARGE co-founder and chair Joubert Roux said the off-grid strategy is aimed at stabilizing long-term transport costs while reducing exposure to fuel price swings and electricity supply interruptions.

He added that the company is preparing for a broader rollout across key transport corridors. 

The company plans to install 60 charging stations nationwide by the end of next year, with further expansion expected afterward.

While early sites focus on passenger vehicles, CHARGE also plans to develop charging hubs for freight trucks along major logistics routes.
