Name of the Project
Khobab and Loeriesfontein wind farm projects.

Location
The Khobab and Loeriesfontein wind farms are located adjacent to each other in the Hantam municipality, in South Africa’s Northern Cape province.

Client
The wind farms are owned by a consortium led by Lekela Power, a joint venture between Actis and Mainstream Renewable Power.

Other members include Thebe Investment Corporation; the IDEAS Managed Fund; Futuregrowth Asset Management; Genesis Eco-Energy, in partnership with Lereko Metier Sustainable Capital; and the Khobab and Loeriesfontein Community Trusts.

Project Description
The project entails the construction of the Khobab and Loeriesfontein wind farms, which will have a combined generation capacity of 280 MW, generated by their 122 wind turbines.

The Loeriesfontein Wind Farm will have sixty-one, 99-m-high wind turbines erected on 3 453 ha of agricultural land. The wind farm will connect to a 132 kV Eskom line.

When operating at full capacity, it will generate about 563 500 MWh/y of clean renewable energy.

Similarly, Khobab Wind Farm will have sixty-one, 99-m-high wind turbines erected on 3 200 ha of agricultural land. The wind farm will connect to a 132 kV Eskom line.

When operating at full capacity, the Khobab Wind Farm will generate about 563 500 MWh/y of clean renewable energy, which will supply electricity to power up to 120 000 South African homes. It will eliminate an estimated 550 000 t/y of carbon emissions, compared with emissions of traditional fossil fuel power plants.

The wind turbines will be supplied by Siemens Wind Power, with the 99-m-high turbine towers being manufactured at the new Gestamp wind turbine tower factory in Atlantis, in the Western Cape. Civil and electrical works will be completed by a consortium comprising Murray & Roberts Construction and Consolidated Power Projects.

The energy generated by the new wind farms will be sold to South African power utility Eskom, in line with the 20-year power supply agreement, as part of the third round of the Department of Energy’s Renewable Energy Independent Power Producer Procurement Programme.

Potential Job Creation
Not stated.

Value
The wind farms represent a total investment of about R7-billion.

Duration
Construction of the wind farms started in September 2015. Both wind farms are expected to be operational in late 2017.

Latest Developments
The Loeriesfontein and Khobab wind farms have been connected to State-owned power utility Eskom’s grid, through Eskom’s Helios substation, and the commissioning of wind turbines has started.

“We energised the wind farm substations on September 28, marking a pivotal point in the construction of . . . the wind farms, and will now continue the process of wind turbine commissioning,” independent renewable-energy developer Mainstream Renewable Power country construction manager Kevin Foster has explained.

Khobab Wind Farm confirmed the completion of all 61 wind turbine generators on September 8, more than two weeks ahead of schedule.

The wind farms are expected to start supplying electricity to the national grid by early December and developers will continue to work closely with the various Eskom teams to achieve this milestone.

Key Contracts and Suppliers
Siemens Wind Power, along with subcontractors Fairwind and BMS (wind turbine installation), Gestamp Wind Turbine Tower Factories (turbine towers) and Murray & Roberts Construction and Consolidated Power Projects (civil and electrical works), DHL and ALE (transport of wind farm components).
