Abstract: Integrated assessment of multi-resource systems, such as water and energy systems, can help achieve more cost-effective and reliable use of resources than planning them independently without considering the interdependencies amongst the systems. This work shows how to integrate water and energy simulation within the open-source Python water resources (Pywr) simulation framework. This enable to explicitly address the interconnections of both water and energy systems to achieve efficient and appropriate spatial and sectoral benefits distribution across the systems. We show an application on a national-scale case study for Ghana in West Africa. We evaluated the impact of increasing penetration of intermittent renewable energy sources on hydrological alteration and water supply demand for different sectors in the country. Results highlight how considering the spatiotemporal multi-sector dynamics of multi-resource systems helps identify synergistic water-energy system designs and management.
