The analysis performed identifies the main drivers among: carbon intensity, generation efficiency, and contribution of fossil generation at the specific and total level of electricity production. The analysis is performed at the aggregate and disaggregated level of fossil fuels. Due to the highly variable behavior of the ACI, a multi-temporal decomposition is performed in the eight presidential administrations in the period of analysis. For each period, the main drivers are identified and the energy policy implications and their effects on the operation and management of the power sector are analyzed. The results show that the main driver is the fossil share of total energy production. Important effects on thermal generation efficiency and fossil energy mix were also identified in some analysis periods. The need for effective long-term policies and regulation in relation to the factors influencing the ACI was identified. It is recommended to accelerate the diversification of the energy mix of the power sector and the permanent monitoring of the behavior of the drivers. info:eu-repo/semantics/openAccess by http://creativecommons.org/licenses/by/3.0/es/ 3.9 2022 ENVIRONMENTAL SCIENCES 114 / 275 = 0.415 2022 Q2 T2 ENVIRONMENTAL STUDIES 48 / 128 = 0.375 2022 Q2 T2 GREEN & SUSTAINABLE SCIENCE & TECHNOLOGY 34 / 46 = 0.739 2022 Q3 T3 GREEN & SUSTAINABLE SCIENCE & TECHNOLOGY 5 / 9 = 0.556 2022 Q3 T2 0.664 2022 Geography, Planning and Development 2022 Q1 Energy Engineering and Power Technology 2022 Q2 Environmental Science (miscellaneous) 2022 Q2 Renewable Energy, Sustainability and the Environment 2022 Q2 Hardware and Architecture 2022 Q2 Management, Monitoring, Policy and Law 2022 Q2 Computer Networks and Communications 2022 Q2 5.8 2022 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Rojas-Lozano, Daniela De Oliveira-De Jesus, Paulo M.
