Two South African wind farms underway

Two of South Africa’s largest Bid Window 4 projects, 140MW Kangnas Wind Farm and 110MW Perdekraal East Wind Farm, have announced the completion of the 28-day strength test of their first foundations, with a significant improvement in the mix design and a massive CO2 saving.

Perdekraal East Wind Farm poured the first of its foundations on 22 November 2018, with Kangnas Wind Farm completing the same milestone the following day. This was followed by a 28-day strength test to ensure that the foundations achieved the required design strengths.

Following the trend that started with the Bid Window3 projects, Kangnas and Perdekraal East Wind Farm’s foundations are designed using a 70% replacement of cement. This signals a significant improvement in the concrete mix design for these turbine foundations.
