Integrated analysis of energy and water supply in islands. Case study of S. Vicente, Cape Verde
The electricity production in the island of S. Vicente is based on fossil fuel and wind and, although there are significant wind resources, they are not fully used because of its intermittent nature. In a previous work, we proposed solutions to tackle this issue. Since this island does not have fresh water available, excess wind electricity can be provided directly to desalination units that can produce desalinated water to supply the population. Other solution studied previously was the use of desalinated water in a pumped hydro system to store the remaining excess wind electricity. In this paper, the scenarios modelled previously are updated with more recent data on energy and water consumption and the respective annual costs are estimated. The results show that with the current wind power and desalination capacity installed in S. Vicente, and with the installation of a pumped hydro system, it is possible to have, by 2020, more than 36% of electricity production from renewable energy sources, together with 59% of the water supplied to the population produced from wind electricity, with costs 10% lower than those forecasted for that year. If the installation of more wind power and desalination capacity is considered, renewable energy sources production can reach 78% (53% wind and 25% hydro), with 93% of wind desalinated water, with about 20% decrease of costs in relation to those predicted for 2020.
