What’s the future for IPPs in South Africa?

  It is most unfair that Eskom now wants to ditch the coal-fired IPPs, when in fact they will be much more useful than the renewables. Moreover, it would be illuminating to see how much cheaper and faster IPP-owned coal-fired power stations can be commissioned than Eskom’s efforts. Coal IPPs should have been the first […]

Lightning protection systems for biogas plants

  Complex and cost-intensive plants with fully automated processes are required to generate useable final products from biomass. A volatile mixture of gas and air is formed in the vicinity of fermentation and gas tanks, which can therefore be classified as potentially explosive atmospheres. Consequently, reliable protection concepts are required to ensure permanent availability and […]

Solar park concept resurfaces in ministerial determination

  The concept of a large solar park, accommodating a substantial solar energy generating capacity was first mooted in 2009, when a proposal to construct a 5 GW solar park in the Upington area was made by the minister of energy. The project has been overshadowed by the success of the REIPPPP, which ran independently […]

Can South Africa afford new “carbon free” power stations?
