A new report on the role of gas in South Africa’s electricity system argues that it would be a “costly mistake” to pursue large gas-to-power investments in light of a shrinking role for gas in the power sector and improving prospects for greener alternatives. Published by the International Institute for Sustainable Development (IISD), the report suggests that a pause be placed on any gas-to-power development until at least 2030. This, given its analysis showing that gas supply to the electricity industry will be unnecessary until 2035, by which date the penetration of variable renewable energy should be such that system balancing would be required.
