The energy-water-climate nexus: Hydropower and climate change in Southern Africa: PHASE 2

See here for details of Phase I: Climate change and upstream development impacts on new hydropower projects in the Zambezi

Climate change assessment of the energy-water nexus in the Zambezi Basin and SAPP

  • Timeframe: February 2014–October 2015
  • Funder: World Bank

Previous regional water modelling studies have not been linked to any electricity supply and demand scenarios for the region. This critical step is necessary to assess how climate change impacts on ZRB hydropower plants would affect the national energy balances of key ZRB riparian states, as well as the overall electricity system performance and evolution in the region.  To make these water-energy links, the World Bank has commissioned the “Climate Change Assessment of the Energy-Water Nexus in the Zambezi River Basin” project.

In February 2014, the World Bank awarded a contract to the University of Cape Town-led consortium to develop a regional electricity supply and demand model, and assess integrated water-energy-climate scenarios for the SAPP countries, particularly how these affect national and regional energy balances and trade. This project also includes an economic assessment of the proposed Batoka Gorge hydropower plant in light of the other developments in the river basin.

The objective of this project is to develop integrated water and power scenarios for the Zambezi River Basin in order to engage stakeholders and inform decision-makers, through an assessment of potential climate change impacts on water availability and energy security in the ZRB and the SAPP. This report is one of the major outputs of the project.

The research team and funders are committed to making this research accessible and in the public domain, including all of the modelling.  This page includes links to all of the final deliverables of the project, including the Water Evaluation and Planning (WEAP) model and underlying datasets behind this.

 Material which will be available soon

Electricity Supply and Demand Scenarios for the Southern African Power Pool: Spalding-Fecher, Randall, Mamahloko Senatla, Francis Yamba, Charlie Heaps, Arthur Chapman, Gilberto Mahumane, Bernard Tembo, Biness Lukwesa, Imasiku Nyambe, and Grayson Himunzowa. 2015.

LEAP model (electricity supply and demand model):  This model uses the Stockholm Environment Institute’s Long-range Energy Alternatives Planning (LEAP) model.  This model is available for download for free to view the file, but those wishing to save changes should apply for a licence with SEI.   Note that the full model is saved as a LEAP “backup” file (“SADC 1.0.leap”), which should be downloaded and then extracted from within LEAP. 

 

Electricity supply assumptions – detailed power plant characteristics: This excel file contains all of the assumptions on existing and new power plants in the region, and the sources of those assumptions (note that the full citations for the sources are in the Final Report).
