The San Kraal wind farm, part of the Koruson 1 project (Round 5 of the Renewable Energy Independent Power Producer Programme, REIPPP) in South Africa, has reached a key milestone by commissioning its first turbines. For this project, Windtechnic Engineering was responsible for the manufacturing of 78 concrete towers and for providing on-site support during their installation, ensuring proper commissioning.
On September 17, 2025, at 2:00 PM, turbine SK15 exported its first kilowatts to the grid, followed shortly by three more turbines. This marks the beginning of the hot commissioning process for the remaining 22 turbines that make up San Kraal, with the goal of achieving Grid Code Compliance by the end of October and commencing commercial operation in November 2025.
A strategic project for South Africa’s energy transition
Koruson 1, developed by a consortium led by EDF Renewables along with its local partners BEE H1 Holdings, Gibb-Crede, and a community trust, consists of three wind farms: Phezukomoya, San Kraal, and Coleskop, with a total installed capacity of 420 MW.
Windtechnic, through its subsidiary Thayvona Concrete Suppliers (Pty) Ltd, and in collaboration with local companies Concrete Units (Pty) Ltd and WBHO Construction (Pty) Ltd, manufactured the towers at a temporary plant built specifically for the project in Middelburg. The plant had the capacity to produce 2.5 towers per week and generated nearly 400 local jobs during the construction phase. The towers, standing 124 meters tall, support Goldwind G165/5.6MW wind turbines.
Commitment to innovation and local impact
Windtechnic’s contribution has strengthened the company’s strategy of promoting local content and reducing carbon footprint through the use of prefabricated concrete structures.
This project adds to Windtechnic’s previous experience in South Africa, where, in collaboration with Concrete Units (Pty) Ltd, it manufactured the towers for the Gouda (2014) and Roggeveld (2019) wind farms, both of which are currently operational.
