Modeling the Water-Energy Nexus: How Do Water Constraints Affect Energy Planning in South Africa?

A new publication on the water-energy nexus has come out of the World Bank's Thirsty Energy Initiative, whose goal is to ensure sustainable development of water and energy resources. This research focuses on incorporating a representation of water supply and infrastructure costs into an energy systems model (SATIM-W) to better reflect the interdependent nature of the energy-water nexus in South Africa and the water supply challenges facing the energy system. The results of this investigation demonstrate the process and type of tools that can be employed to examine the energy-water nexus in a national level planning context, and the insights that can be gained from water-smart energy planning.
