Karreebosch Wind Farm is a 140 MW wind energy project in South Africa’s Karoo region, developed by G7 Renewable Energies, a Cape Town-based independent power producer (IPP) and renewable energy developer.
The project is one of the first privately developed wind farms in the Karoo and one of the largest wind energy facilities in the region, contributing to South Africa’s renewable energy transition and private power generation capacity.
Founded in 2008, G7 Renewable Energies develops, owns and advances utility-scale renewable energy projects across South Africa, including wind, solar photovoltaic (PV) and battery energy storage systems (BESS).
G7 has developed several wind farm projects since its inception, namely Roggeveld, Brandvalley, Witberg, Klawer, and Rietkloof, as well as the groundbreaking Oya Hybrid Energy Project, which comprises Solar, Wind, and Storage, for the South African Risk Mitigation IPP Procurement Programme. Karreebosch will be the first Wind Farm that G7 will build, own and operate.
G7 Renewable Energies Pty Ltd, Cennergi Holdings Pty Ltd (a wholly owned subsidiary of Exxaro Resources Limited) and Northam Platinum Holdings Limited announced the finalisation of a power purchase agreement for the 140MW Karreebosch Wind Farm in February 2025. The project will supply clean, renewable energy to Northam’s mining operations. The final, and 25th Turbine was installed on 13 September 2026.
