Exogenous water demand is calculated based on data on water demand coefficients and cooling shares.
Limitations Water demand is calculated in a post-processing of REMIND and not part of the optimization.
Exogenous water demand is calculated based on data on water demand coefficients and cooling shares. Vintage structure in combination with time dependent cooling shares as vintages and efficiency factors are also considered. Demand is a function of excess heat as opposed to electricity output.
Limitations Water demand is calculated in a post-processing of REMIND and not part of the optimization.
The off-realization of the water module takes no water demand into account.
Limitations REMIND calculates no results regarding water demand.
