A new EU report on water-energy systems sponsored by European Commission DG-RTD

Energy and water systems are highly interdependent, yet seldom planned and managed together, overlooking synergies and combined risks. The developed soft linkage of models maps future hydro-climatic projections into future power system operation, and allows to quantify the vulnerability of the power system to changes in the hydrological system due to climate change.
Danube region, Iberian Peninsula, Alpine region and the Adda river basin (high-resolution) are analyzed in the study.
Results show that climate change and renewable energy penetration will have significant effects on the reliability and vulnerability of the energy system in the different regions also impacting energy prices.
The NRM group substantially contributed to the project providing projections of water temperature and streamflow with daily resolution at more than 350 specific locations.

River Basin Development @ IHA World Congress in Paris

The International Hydropower Association held the World Hydropower Congress in Paris. The World Hydropower Congress brings together industry, government, finance, civil society and academia to set priorities for the hydropower sector.  The theme, ‘The Power of Water in a Sustainable, Interconnected World’, focuses on hydropower’s role in delivering on the Paris Agreement and the Sustainable Development Goals. Andrea Castelletti was one of the speakers in the session on River Basin Development and panelist in the subsequent discussion moderated by IUCN with Julien Harou, Hellen Nabwala Natu,  Amy Newsock, and Yunhua Chen. Andrea presented our recent results on the optimal dam filling applied to the Gibe III and Koysha dam on the Omo-Turkana basin.

A NOVEL APPROACH FOR OPTIMALLY DESIGNING WATER-ENERGY SYSTEMS IN SMALL, OFF-GRID ISLANDS. A NEW PAPER ON APPLIED ENERGY

Small Mediterranean islands are remote, off-grid communities characterized by carbon intensive electricity systems coupled with high energy consuming desalination technologies to produce potable water. The aim of this study is to propose a novel dynamic, multi-objective optimization approach for improving the sustainability of small islands through the introduction of renewable energy sources. The main contributions of our approach include: (i) dynamic modelling of desalination plant operations, (ii) joint optimization of system design and operations, (iii) multi-objective optimization to explore trade-offs between potentially conflicting objectives. We test our approach on the real case study of the Italian Ustica island by means of a comparative analysis with a traditional non-dynamic, least cost optimization approach. Read more HERE
