Koruson 1 Wind Power Cluster

completed

The Koruson 1 wind power cluster is a 420 MW renewable energy project located between Noupoort and Middelburg, straddling the Eastern Cape and Northern Cape in South Africa. It features larger, higher-capacity wind turbines rated at 5.6 MW each, combining permanent magnet direct drive technology with full-power conversion synchronous generators to enhance efficiency and grid support. The cluster includes the San Kraal, Phezukomoya, and Coleskop wind farms and reached commercial operation in February 2026, supplying power under 20-year power purchase agreements. The development also includes South Africa's largest privately developed 400/132 kV main transmission substation, with capacity to connect up to 1.5 GW of renewable energy to the grid. The project used post-tensioned concrete towers manufactured locally, supporting local content and job creation.
