First, the scenarios have been created according to the possible evolution that may experience the Spanish electric power system. The scenarios vary considering the possible evolution of the generation mix and the demand. Then, the model used to perform the analysis, ARIES, has been updated. For that, it is necessary to fed the model with historical and forward series of the different commodities intervening in the model, as well as other data like the demand growth, the capacity installed of the different technologies etc. Part of this data has been obtained from the Risk Management department of Endesa. Since this data is confidential, the results of the simulations have been described in a qualitative manner. Finally, the model is executed and the obtained results are analyzed in other to establish which are the most advantageous scenarios for the company and what measures can undertake to limit the adverse effects. vii UNIVERSIDAD PONTIFICIA DE COMILLAS ESCUELA TECNICA SUPERIOR DE INGENIERIA (ICAI) MASTER IN THE ELECTRIC POWER INDUSTRY viii UNIVERSIDAD PONTIFICIA DE COMILLAS ESCUELA TECNICA SUPERIOR DE INGENIERIA (ICAI) MASTER IN THE ELECTRIC POWER INDUSTRY TABLE OF CONTENTS ABSTRACT ........................................................................................................................ vii TABLE OF CONTENTS ........................................................................................................ ix LIST OF FIGURES ............................................................................................................... xi LIST OF TABLES ................................................................................................................ xiii 1 INTRODUCTION ........................................................................................................ 1 1.1 Motivation ............................................................................................................ 1 1.2 Goals ..................................................................................................................... 3 1.3 Methodology ........................................................................................................ 4 2 STATE OF THE ART .................................................................................................... 5 2.1 The model ARIES ................................................................................................... 5 2.1.1 General description of the model ................................................................. 5 2.1.2 Prices simulation module .............................................................................. 6 2.1.3 Electric market simulation module ............................................................... 7 2.2 Energy generation in Spain ................................................................................... 8 2.2.1 European Regulation ..................................................................................... 9 2.2.2 Nuclear power plants .................................................................................. 12 2.2.3 Coal-fueled power plants ............................................................................ 15 2.2.4 CCGT power plants ...................................................................................... 18 2.2.5 Renewable energy sources ......................................................................... 20 2.3 Energy demand in Spain ..................................................................................... 24 3 COST OF RISK IN RELATION TO THE GENERATION MIX ......................................... 29 3.1 Inputs to the model ............................................................................................ 29 3.1.1 Historic and forwards of the commodities ................................................. 29 3.1.2 Scenario definition ...................................................................................... 29 3.2 Risk Analysis ........................................................................................................ 32 3.2.1 Risk evaluation tools and definitions .......................................................... 32 3.2.2 Scenario 1 .................................................................................................... 33 3.2.3 Scenario 2 .................................................................................................... 35 3.2.4 Scenario 3 .................................................................................................... 35 3.2.5 Scenario 4 .................................................................................................... 36 3.2.6 Scenario comparison ................................................................................... 37 4 CONCLUSIONS ........................................................................................................ 41 BIBLIOGRAPHY ................................................................................................................. 43 ix UNIVERSIDAD PONTIFICIA DE COMILLAS ESCUELA TECNICA SUPERIOR DE INGENIERIA (ICAI) MASTER IN THE ELECTRIC POWER INDUSTRY x UNIVERSIDAD PONTIFICIA DE COMILLAS ESCUELA TECNICA SUPERIOR DE INGENIERIA (ICAI) MASTER IN THE ELECTRIC POWER INDUSTRY LIST OF FIGURES Figure 1 -
