3 March 2008 – Eskom has released a call for tender for the development of a 100MW wind farm for the Cape west coast, near Vredendal. At this stage, the utility is applying for a licence a conducting an environmental impact assessment for the site.
"The area supports other technical requirements for a wind energy facility, in terms of land availability and accessibility to the electricity grid to meet transmission integration requirements," said Eskom.
It is proposed to erect 50 2MW turbines on the site, an area of some 25km2. The project, estimated at US$146 million is set for late 2009 or early 2010.
A number of metrological conditions are being considered for the wind farm, including wind speed variations and consistency.
"A 300km2 area of wind machines would be necessary to produce the same power generated by one large coal-fired or nuclear power station, assuming the wind blows all the time at roughly 50km/h," Eskom said.
