Ítem Floating photovoltaics systems on water irrigation ponds: Technical potential and multi-benefits analysis(Elsevier, 2023-05-15) Muñoz-Cerón, Emilio; Osorio-Aravena, Juan Carlos; Rodríguez-Segura, Francisco Javier; Frolova, Marina; Ruano-Quesada, Antonio AntonioFloating photovoltaic systems (FPV) can be a more sustainable alternative for the energy transition than ground-mounted photovoltaic systems, as they avoid occupying useable land and the power generation is more distributed. This paper presents the first study that calculates the FPV technical potential at the province/municipality level, focusing on water irrigation ponds, which it is a novelty in the literature that usually focuses on large water infrastructures in a national approach. In the province of Jaén (Spain), more than 3000 ponds dedicated to agricultural irrigation have been identified and their surface area and location was obtained. The results, calculated for each pond, reveal that, in a conservative scenario, in which only 25% of their surface area is covered, a minimum of 490 MWp can be installed, which can provide 251% of the province agricultural electricity consumption and 27% of the total electricity needs. This analysis has also been performed at the municipal level, where all possible FPV plants have been aggregated and compared with consumption that would be covered at this scale. Furthermore, this technology brings additional benefits, as it avoids the occupation of 12 km2 of useable land, 8.8·106 m3/year of water evaporated, while creating more than 7000 jobs.Ítem How much solar PV, wind and biomass energy could be implemented in short-term? A multi-criteria GIS-based approach applied to the province of Jaén, Spain(Elsevier, 2022-05) Osorio-Aravena, Juan Carlos; Rodríguez-Segura, Francisco Javier; Frolova, Marina; Terrados-Cepeda, Julio; Muñoz-Cerón, EmilioThe progress made in the penetration of renewable energy (RE) sources in most parts of the world is not fast enough for achieving the international climate mitigation targets. Furthermore, there is a lack of energy planning strategies, methods and tools for assessing the implementation of RE technologies which considers the social support. In this work, we present a replicable multi-criteria spatial approach based on geographical information system to estimate the potential of solar photovoltaic (PV), wind and biomass energy technologies that could be implemented in the short-term in a given territory. This potential includes environmental, technical (with economic attributes) and geographical (with social-acceptability attributes) constraints, together with existing local power plants considerations for calculating the electricity generation by technology, and then estimating its jobs creation and greenhouse gas emissions reduction. The approach was applied to the province of Jaén (Southern Spain), which has a pronounced unbalance between its inner electricity production and consumption and apparently is a territory with great technical potential for the aforementioned technologies. Results show that this province has a short-term implementable potential that would annually produce 8.9 TWh from solar PV, 911 GWh from wind energy and 683 GWh from biomass plants; which is 3.8 times greater than the current electricity consumption and would require 1.5% of the total surface of Jaén. This potential can create about 92,800 direct jobs and avoid the emissions of 3.78–8.61 MtCO2 to the atmosphere. The proposed approach can be useful for energy planning processes and for allowing decision-making to accelerate the implementation of RE power plants in order to achieve the climate mitigation goals.Ítem Identifying barriers and opportunities in the deployment of the residential photovoltaic prosumer segment in Chile(Elsevier, 2021-06) Osorio-Aravena, Juan Carlos; de la Casa, Juan; Töfflinger, Jan Amaru; Muñoz-Cerón, EmilioPhotovoltaic (PV) prosumers can play a significant role in the transition toward sustainable cities. However, the implementation of more effective policies which accelerate the deployment of this market is needed. In this study, after an overview of the residential PV prosumer (RPVP) market's status in Chile, critical parameters that can speed-up the deployment of this segment through policy decisions were identified. Considering the local conditions of each regional capital in Chile, the segment is analyzed with widely-used econometric techniques to evaluate the residential PV systems feasibility empirically. The results show that the Chilean regulatory framework is insufficient for exploiting the potential of the RPVP. Without effective policy instruments, high investment costs and low income per household are the main barriers in the deployment of the segment in this country. Therefore, suitable promotion energy policies, regulatory changes, and financing options can accelerate the deployment without majorly impacting on the national budget. This would let citizens help accelerate decarbonization through a more decentralized and democratic energy transition, gaining socio-economic and socio-environmental benefits, based on solar PV technology.Ítem Social acceptance of renewable energy development in southern Spain: Exploring tendencies, locations, criteria and situations(Elsevier, 2023-02) Rodríguez-Segura, Francisco Javier; Osorio-Aravena, Juan Carlos; Frolova, Marina; Terrados-Cepeda, Julio; Muñoz-Cerón, EmilioAlthough, in general, there is a high level of public acceptance of renewable energies (RE) in Spain, at a local scale, protests and campaigns against RE projects are becoming increasingly frequent. In order to identify the factors that most influence the acceptance/rejection of renewable electricity generation technologies (photovoltaic, wind and biomass) at a local level, in this study we conducted a structured survey of the population of the province of Jaén in southern Spain. The analysis of the results of the questionnaire reveals that the social acceptance of RE plants is influenced by their location and size, and identifies the main criteria and situations that people take into consideration when deciding whether to support or reject RE projects. Although the results suggest that all RE technologies are widely accepted, they also highlight a preference for photovoltaic energy and for medium-sized plants in sites with low natural value. This article provides information and recommendations to facilitate the drafting of policies, plans and future studies that will enable social barriers to the implementation of RE technologies to be reduced, so helping accelerate the energy transition that is required in order for agreed climate targets to be met.Ítem Spatial Energy Planning: A Review(MDPI, 2020-10-15) Osorio-Aravena, Juan Carlos; Frolova, Marina; Terrados-Cepeda, Julio; Muñoz-Cerón, EmilioDespite the fact that some renewable energy (RE) technologies are already techno-economically viable, the high spatial dilution nature of their sources, together with aspects beyond the techno-economic ones (such as environmental, social, cultural, and other aspects), can become strong constraints and barriers when it comes to their integration into electric systems. Therefore, with the objective of determining whether studies on spatial energy planning (SEP) are addressing these issues, a systematic review has been carried out to address whether SEP studies are considering aspects beyond the techno-economic ones when integrating RE technologies and, if they are being considered, how they are addressed in their analyses and what criteria, factors, and indicators of the aspects that are employed. Apart from the revelation that the concept of SEP has been included within high-quality scientific literature for less than ten years, SEP seems to be an unexploited tool with the potential to provide significant insight into a planning process that could prevent conflicts when integrating RE technologies into electric systems. This would be useful for decision-makers and for accelerating a sustainable energy transition.Ítem Synergies of electrical and sectoral integration: Analysing geographical multi-node scenarios with sector coupling variations for a transition towards a fully renewables-based energy system(Elsevier, 2023-09-15) Osorio-Aravena, Juan Carlos; Aghahosseini, Arman; Bogdanov, Dmitrii; Caldera, Upeksha; Ghorbani, Narges; Mensah, Theophilus Nii Odai; Haas, Jannik; Muñoz-Cerón, Emilio; Breyer, ChristianThe cost-optimal pathway for moving from the current fossil-fuel based energy system to 100% renewables is still an open question. This work presents the first study that analyses the transition towards a 100% renewable energy system under different spatial resolutions (1-node, 6-nodes electrically isolated and interconnected) and various coupling configurations for the power, heat, transport and desalination sectors. With the LUT Energy System Transition Model for the case of Chile, 12 scenarios were investigated in an hourly resolution and considering more than one hundred energy-related technologies. The results show that: (1) 1-node systems deliver too simplistic results for key metrics; (2) power sector simulations can lead to a strongly distorted resources allocation compared to scenarios that include other sectors; (3) a multi-node model better reflects transmission bottlenecks and local resources, and; (4) the lowest-cost solution is reached when power transmission lines are considered. Thus, it is concluded that a cost-optimal, balanced, and realistic solution to reach a fully defossilised energy system is transitioning towards a multi-node, interconnected, and fully sector-coupled energy system. This can be called, in short, the ‘Power-to-X economy’, which in the case of Chile would more accurately be a ‘Solar-to-X economy’, given the high solar share found in the simulations.Ítem The impact of renewable energy and sector coupling on the pathway towards a sustainable energy system in Chile(Elsevier, 2021-11) Osorio-Aravena, Juan Carlos; Aghahosseini, Arman; Bogdanov, Dmitrii; Caldera, Upeksha; Ghorbani, Narges; Mensah, Theophilus Nii Odai; Khalili, Siavash; Muñoz-Cerón, Emilio; Breyer, ChristianThe aim of this research is to analyse the impact of renewable energy (RE) technologies and sector coupling via analysing the transition pathways towards a sustainable energy system in Chile. Four energy transition scenarios for the power, heat, transport and desalination sectors were assessed using the LUT Energy System Transition model. The current policy scenario was modelled and compared with three best policy scenarios. The results showed that the transition to a 100 % renewable-based energy system by 2050 is technically feasible. Further, such an energy system would be more cost-efficient than the current policy scenario to reach carbon neutrality by 2050. The results also indicate that Chile could reach carbon neutrality by 2030 and become a negative greenhouse gas emitter country by 2035. In a 100 % renewable-based energy system, solar photovoltaics (PV) would contribute 86 % of electricity generation, which would represent 83 % of the total final energy demand for the year 2050. This would imply the use of about 10 % of the available techno-economic RE potential of the country. Three vital elements (high level of renewable electrification across all sectors, flexibility and RE-based fuel production) and three key enablers (solar PV, interconnection and full sectoral integration) were identified in order to transition to a fully sustainable energy system. Chile could contribute to the global sustainable energy transition and advance to the global post-fossil fuels economy through the clean extraction of key raw materials and RE-based fuels and chemicals production.Ítem The role of solar PV, wind energy, and storage technologies in the transition toward a fully sustainable energy system in Chile by 2050 across power, heat, transport and desalination sectors(Aalborg University Open Publishing., 2020-06-24) Osorio-Aravena, Juan Carlos; Aghahosseini, Arman; Bogdanov, Dmitrii; Caldera, Upeksha; Muñoz-Cerón, Emilio; Breyer, ChristianRenewable energies will play a significant role in a sustainable energy system in order to match the goal under the Paris Agreement. However, to achieve the goal it will be necessary to find the best country pathway, with global repercussion. This study reveals that an energy system based on 100% renewable resources in Chile could be technically feasible and even more cost-efficient than the current system. The Chilean energy system transition would imply a high level of electrification across all sectors, direct and indirectly. Simulation results using the LUT Energy System Transition model show that the primary electricity demand would rise from 31.1 TWh to 231 TWh by 2050, which represent about 78% of the total primary energy demand. Renewable electricity will mainly come from solar PV and wind energy technologies. Solar PV and wind energy installed capacities across all sectors would increase from 1.1 GW and 0.8 GW in 2015 to 43.6 GW and 24.8 GW by 2050, respectively. In consequence, the levelised cost of energy will be reduced in about 25%. Moreover, the Chilean energy system in 2050 would emit zero greenhouse gases. Additionally, Chile would become a country free of energy imports.Ítem Typical Daily Profiles, a novel approach for photovoltaics performance assessment: Case study on large-scale systems in Chile(Elsevier, 2021-09) Ascencio-Vásquez, Julián; Osorio-Aravena, Juan Carlos; Brecl, Kristijan; Muñoz-Cerón, Emilio; Topič, MarkoA growing photovoltaic industry shows exponential deployment worldwide, and it is expected to largely contribute to the energy transition. Because PV technologies will play a major role in achieving global sustainable development and climate goals, driving more energy-efficient scenarios will require efficient approaches to evaluate systems, especially when dealing with big data of a large region or portfolio. In this work, a novel approach for the PV performance assessment of photovoltaic systems, called “Typical Daily Profiles” (TDP), is presented. This approach is tested on the entire PV fleet operating in Chile from 2014 to 2019. The TDP approach can help to calculate key performance indicators, identify the mounting configuration of PV systems, and to detect major technical issues. A detailed validation carried on the Chilean PV fleet confirms the TDP approach's capabilities to provide accurate PV performance results, neglecting external factors such as failures, grid curtailment, or poor operation activities. Chile was chosen due to the large variety of climate zones in its unique geography, which helps to understand the PV performance under different environmental conditions. Besides, this study reveals the immense potential of PV technologies in Chile compared to mature PV markets worldwide. On an annual basis, their unit capacity factors can reach up to 38%, performance ratios above 90%, and the highest energy yield close to 3350 kWh/kWp. Proving to be an accurate tool, the Typical Daily Profiles approach can be easily applied to other PV portfolios in different regions, and a periodical execution could help to identify and understand long-term performance losses.
