Analysis of Economically Viable Potential of Renewables in Malta Energy System

With an absolute dependence on imported fossil fuels, and no interconnection to the European or African electrical grid as yet, Malta?s energy system is a fragile one being a factor of a lot of international factors. In order to reduce this dependence, the importance to integrate other sources of energy to our system is of utmost importance. Situated in the centre of the Mediterranean, Malta gains from high solar energy and the potential of other renewable sources such as wind, biomass wastes, landfill gases and sewage treatment plants are very encouraging. The integration of such technologies, together with demand side management, will, apart from increasing our security of supply help reduce CO2 emissions in controlling global warming. Intelligent investment can also lead to substantial financial savings by applying schemes such as European trading scheme which further promote this control. This study aims to investigate the electrical load tendencies of the country as a function of its climate and seasonal industries such as tourism. This eventually leads a projected load growth from which investments have to be made. At this stage, three investment scenarios are proposed varying from a fossil fuel scenario, to a scenario integrating ?mature? renewable energy technologies such as wind and photovoltaic to a future scenario where hydrogen is being produced to cover a certain percentage of fuel for transport, the excess being used for electricity. The study quantifies expenses and investments whilst also considers the effect of European obligations and consequences. The performed analysis shows that the situation in Malta is quite critical with a lot that has to be done in a short time. A price increase in electricity is inevitable, however, combining technology, utilising the potential of the island and understanding the responsibility of each individual in the system, will surely lead to a better situation. The results obtained are compared and presented in the thesis.
