The roles of private sector IPPs and Eskom in renewable energy in SA

  An interview with the South African Renewable Energy Council EE Publishers initially proposed an interview with Eskom on its position and role in respect of renewable energy in South Africa. Eskom agreed and requested the interview questions in advance. However after the interview questions were provided, Eskom failed to engage further or provide answers […]

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?

  The editorial on the cost of carbon free new build power stations, which was published on page 3 in the June 2016 edition of Energize, elicited a wide response, and this is a more detailed version to demonstrate the source of the arguments. The core issue here is the cost of building new nuclear […]

Scaling up variable renewable power: the role of grid codes

  The power sector globally is accelerating its transition towards a sustainable energy regime. Since 2011, over 100 GW of annual capacity additions have been from renewables: more than fossil fuel and nuclear power additions combined. The share of renewables in total electricity production in 2014 exceeded 22%. Hydropower accounted for 16,4% and variable renewable […]
