To address water scarcity, South Africa is reducing water use in the electricity sector. The country’s Integrated Resource Plan (IRP), developed by the South Africa Department of Energy, includes water use as a key criterion for assessing longer-term electricity-sector investments. Under the process that led to IRP adoption in 2011, the Department of Energy and partners assessed electricity-sector options in relation to critical development and climate criteria, which served as the foundation for decision making. The IRP is also highlighted in South Africa’s INDC as a “climate compatible sectoral plan” that represents good progress in supporting GHG emission reductions. Several good practices used in developing South Africa’s 2011 IRP, detailed in the cases studies, are highlighted below.
