DEPARTMENT OF TECHNOLOGY AND BUILT ENVIRONMENT STUDY OF THE ENERGY SYSTEM OF THE AUTONOMOUS COMMUNITY OF THE BASQUE COUNTRY Maitane Blanco Gabilondo June 2009 Master’s Thesis in Energy Systems Supervisor: Alemayehu Gebremedhin Examiner: Alemayehu Gebremedhin Preface This study was carried out as a final thesis at the Master Programme in Energy Systems at the University of Gävle. First of all, I would like to thank my supervisor Alemayehu Gebremedhin, whose attention, comments and advice have been of great help for the development of my work. Secondly, I would like to show gratitude to Ana Madurga from the University of the Basque Country, for her help during the time of the realization of the thesis. I would like to thank all the other people involved in this thesis work by information and support in various ways, no one mentioned, no one forgotten. I would also like to thank all my Erasmus fellows and particularly Natalia, my opponent, who has given me valuable comments and advise. And what is even more important to me, they help me going through this year abroad, making me feeling like home. Celia and Ewa: home, sweet home. Finally I would like to give my deepest thanks to my family and especially to my boyfriend Joseba. Thank you for being so patient during my study years, for being there always: supporting me and encouraging me. There are no words to express my love and gratitude. June 2009 Maitane Blanco Gabilondo Abstract This paper analyzes the energy system of the autonomous community of the Basque Country. The aim of study is to analyze the current situation in the energy field of the autonomous community of the Basque Country, which is a region of the north of Spain with a problem of energy dependency. 95% of the energy consumed in the region comes from out the borders, which is among the highest rates of the European Union. Therefore, based on gathered information an energy survey of the region has been made, to understand the in and outs of the system, to know which are the energy flows of the region. In 2007 the energy available for gross inland consumption was 7 774 ktoe, where 40.6% comes from petroleum and 39.2% from natural gas. In other words, it is a system characterized by a high consumption of fossil fuels. Renewable energy plays an important role in every future energy scenario of every country, also in the Basque energy system. Hence current situation is analyzed to get a general idea of the situation of them in the system. Renewable energy is only 5.1% of the energy available for gross inland consumption and thus there is still a lot of work to do with it. Waste treatment has been analyzed as the key for comfort in modern society, but also a problem that every region has to face. The amounts of waste generated in 2005 was 1 165 799 tones, which is the equivalent of 545.6 kg per capita and it is increasing every year. The waste treatment facilities are now in a crossroad in the region and it is there where the proposal takes place. Landfilling is not an affordable option in a small region with high population density like the autonomous community of the Basque Country. As waste can be used as a fuel in power plants, why do not take advantage of both problems? Then, two new incineration plants like the one that already exist in the region are proposed. The new installations will replace 88 000 toe per year of primary energy and reduce the emissions of CO2 to the atmosphere 880 000 t per year. The conclusion that could be drawn from this study is that the proposal is not going to give an answer to all the problems of the energy system, but it will be clearly a good step forward. It will solve at the same time the problem of energy dependency, reducing it to 93.47%, and the problem of waste treatment facilities.
