Eskom’s Sere Wind Farm near Vredendal in the Western Cape has achieved its full commercial operational capacity of 100MW.

In a statement on Monday, the utility said the wind farm achieved full commercial operational capacity on 31 March in line with the commitments by Eskom in terms of both time and cost.

“The Sere plant adds 100MW to the national power grid and contributes to saving nearly six million tons of greenhouse gas emissions over its 20 years expected operating life, with average annual energy production of about 298 000 MWh — enough to supply about 124 000 standard homes,” said Eskom acting Chief Executive Officer Brian Molefe.

The utility said all 46 wind turbines have been erected and energised, and the construction of the new Skaapvlei substation and a 44-kilometre 132kV distribution line has been completed.

The first wind turbine at the farm was erected in December 2013. The project took the first step towards the goal of synchronising wind turbines to the grid when the first string of seven turbines was energised on 6 October 2014.

Although Sere had been completely energised and feeding power to the grid since 30 December 2014, the first quarter of 2015 was used to ensure that the milestone of commercial operation is achieved.

The wind farm is Eskom’s first utility scale renewable energy project. Molefe said the project is one of the largest wind energy projects in the country and is important in showing the utility’s commitment to the growing role that renewable power will play in the future.

Since the energising of the first wind turbine in October 2014, Sere has contributed over 90 GWhrs of energy to the national power grid.

The World Bank, African Development Bank, Clean Technology Fund and Agence Française de Dévelopement helped to fund the project.
