Given increasing urban population, environmental issues and limited natural resources, long-term planning of water supply systems driven by renewable energies is the only way towards affordable secure and sustainable water and energy future. In this context, daily surplus output from grid-connected rooftop photovoltaics (PVs) is a promising clean energy source to be considered in urban water-related energy mix. In this paper, we address the optimal strategic investment decisions of an urban desalination-based water supply system driven by grid electricity and surplus PVs output, considering real-time operational constraints. The model is formulated as a two-level mixed integer linear programming (MILP) problem. The real-time operational constraints associated with water production, storage and transfer are integrated with yearly planning constraints corresponding to desalination plants, storage tanks and pipeline capacities and locations. The optimal decisions are obtained such that the operation of the water supply system has the most compatibility with available renewable energy. The capabilities of the proposed model are tested through a case-study from north-western corridor of Perth, Western Australia.
