Large-scale gas use for power generation is central to energy policy direction in South Africa, but this policy rests on a 2012 vision which pre-dates dramatic reductions in renewable energy costs and carbon emissions space. In this report, we demonstrate that the economically rational role for gas in power generation is limited to where it can viably replace diesel as a fuel for peaking plants – far from the large-scale Gas-to-Power direction of current energy policy.
