Resumen
THE NEED TO GET AN APPROPRIATE QUANTIFICATION OF THE SUSTAINABILITY INDICATORS INVOLVES THE USE OF SITE-SPECIFIC INFORMATION THAT COULD COME FROM SEVERAL SOURCES, AFFECTING ITS QUALITY. THIS STUDY ANALYSES THE QUALITY AND SOURCES TO BUILD EIGHT ENVIRONMENTAL, SEVEN SOCIAL AND FOUR ECONOMIC INDICATORS FOR EIGHT ELECTRICITY GENERATION TECHNOLOGIES IN 2005, 2009 AND 2015 AS REFERENCE YEARS, FOLLOWING THE ISO 14.040-44:2006 LIFE CYCLE ASSESSMENT APPROACH. THE RESULTS SHOW FOR THE THREE DIMENSIONS IMPORTANT DIFFERENCES AMONG THE PERIODS, REACHING OVER 400% OF REDUCTION IN 2015 IN CASE OF ACIDIFICATION FOR COAL POWER PLANTS, THANKS TO ENVIRONMENTAL REGULATIONS. FOR LEVELIZED ELECTRICITY COST AND CORRUPTION INDEX, THE VARIATIONS REACH AROUND 40% AND 30%, MAINLY FOR FOSSIL FUEL-BASED POWER PLANTS. THESE CHANGES SUPPORT THE NEED TO HAVE A CENTRALIZED, RELIABLE AND ACCURATE DATA SYSTEM OF REGISTRATION, IN ORDER TO CONTRIBUTE TO THE SUSTAINABILITY OF THE ELECTRICITY SYSTEM IN CHILE.
