| description |
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 research methodology developed embeds the
various water supply options in a least cost optimization
energy planning tool, so that the cost of water is captured.
A key feature of the developed SATIM-W model is that it
regionalizes power generaation, refining, and energy
resource supply, thereby introducing a spatial dimension to
the water demands of the energy sector. It also contains a
regionalized structure of the basins and delivery
infrastructure that would be required to supply the energy
sector and assesses the impact of meeting those needs on the
cost of supplying water. 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. A number of relevant
policy scenarios in South Africa were explored, and the
results show that specific energy sector policies can have
significant implication for both new investment in water
supply infrastructure and in some cases can lead to stranded
energy and water investments, reinforcing the importance of
planning these sectors through a nexus approach. This case
study is the first time the cost of water supply has been
assessed in a sector wide energy supply expansion plan. By
documenting the methodology, the authors aim to help energy
sector planners and modelers properly incorporate water
constraints in their work. |
