South Africa hit a world-class clean-energy milestone as Seriti Green handed over the R1-billion Vunumoya main transmission station (MTS) to Eskom, energised ahead of schedule and now feeding 155MW of wind power into the national grid.

The project, which was handed over in Bethal this week, anchors a 900MW rollout that positions Mpumalanga as a future hub for renewable energy and low-carbon mining, marking a decisive step in the country’s bid to accelerate clean power supply and stabilise the grid.

Vunumoya is a Nguni expression that literally means “harvesting the wind”.

The Vunumoya MTS, over 18 months in the works by Seriti Green, is now operational and integrated into the national system, a feat achieved four months ahead of its original commissioning date of March next year.

Speaking at the handover, Seriti Group CEO Mike Teke said the milestone reflects what is possible when private and public actors work in sync for national benefit.

“Today's handover of the Vunumoya MTS demonstrates what an effective partnership can achieve. This is a meaningful milestone for South Africa’s energy transition and for Mpumalanga’s future as a renewable energy hub.
