This story was first published on 19 October when Vestas announced orders for the Karusa and Soetwater projects. It was updated on 1 November when the manufacurer announced the turbine purchase agreement for Oyster Bay.
It will supply, install and commission 70 units of its V136-4.2MW model for the Karusa and Soetwater projects, both of which are 147MW and located in the Western Cape. They will each feature 35 turbines with hub heights of 82 metres.
The manufacturer will also provide 41 V117-3.45MW turbines delivered in 3.6MW power optimised mode for Enel Green Power's 148MW Oyster Bay wind farm in the Eastern Cape. The turbines will have hub heights of 91.5 metres.
It will also service the three sites for five years.
Vestas’ Southern Africa division will use locally produced towers for the projects, delivering local content, creating jobs and supporting social economic development, the manufacturer explained.
Bids in South Africa’s renewables procurement plan (REIPP) are judged on price (70%) and seven economic development objectives (30%), including job creation and local content.
To lower downtime and levelised cost of energy (LCOE), the turbines at the three Enel Green Power projects will also include a Scada solution (supervisory control and data acquisition), Vestas stated.
Turbine delivery and installation is planned for the second half of 2020.
Enel was awarded capacity for the Karusa, Soetwater and Oyster Bay projects in the fourth tender round under South Africa’s renewables procurement plan (REIPP) April 2015.
However, state utility Eskom did not sign power purchase agreements (PPAs) for the two wind farms — and for 25 other renewable energy projects — until April 2018.
