    A Brazilian perspective of power systems integration using OSeMOSYS SAMBA – South America Model Base – and the bargaining power of neighbouring countries : a cooperative games approach.
    (2018) Moura, Gustavo Nikolaus Pinto de; Legey, Luiz Fernando Loureiro; Howells, Mark
    This paper intends to contribute to a better understanding of both advantages and drawbacks of power systems interconnection processes between Brazil and its South American neighbours. Based on data available in national and international reports, three scenarios for the power supply sector expansion were modelled in OSeMOSYS. The Brazilian perspective of power integration considers funding strategic hydro projects in Argentina, Bolivia, Guyana and Peru. An alternative to the power integration process considers higher penetration of distributed photovoltaics and biogas power plants as well as lower hydro capacity expansion in Brazil. Features related to costs, carbon emissions, hydro reservoirs, technological performance, electricity demand, population growth, time zones and reserve margin were considered. The comparison of different scenarios provides insights regarding the contribution of renewable energy generation and sheds light on cross-border trade perspectives between Brazil and other countries in South America. Using a cooperative games approach, the bargaining power of each country (player) was calculated by applying the Shapley value concept. Argentina, Brazil, Paraguay, Peru and Guyana have the largest bargaining power, either as exporter or importer.

    Energia renovável : Diagnóstico da geração de eletricidade em pequenas centrais hidrelétricas no Estado de Minas Gerais.
    (2008) Moura, Gustavo Nikolaus Pinto de; Santi, Auxiliadora Maria Moura
    As Pequenas Centrais Hidrelétricas (PCH’s) são consideradas importantes fontes para geração de eletricidade no Brasil em tempos recentes, tendo em vista sua classificação como fonte de energia renovável, as crescentes demandas por eletriciddade e os prognósticos catastróficos do aquecimento global. Neste contexto, propôs-se elaborar um diagnóstico da geração de eletricidade em Pequenas Centrais Hidrelétricas no Estado de Minas Gerais, considerando a legislação básica, os programas governamentais, as características tecnológicas das usinas, as bacias hidrográficas nas quais as PCH’s estão instaladas, os impactos ambientais associados à implantação desses empreendimentos, o número de PCH’s em operação, em fase de construção ou em fase de outorga, os agentes econômicos proprietários das PCH’s e o destino da energia gerada. Constatou-se que há 78 PCH’s em operação, 9 em construção e 48 em outorga, em Minas Gerais. O maior número de PCH’s em operação, representando 92,5% do número total das PCH’s no Estado e 90,3% da potência instalada das PCH’s encontra-se instalado nas bacias hidrográficas do rio São Francisco, Doce, Grande e Paraíba do Sul . O setor têxtil possui cinco empresas, o maior número de Autoprodutores de Energia Elétrica em PCH’. É notável a participação das indústrias metalúrgicas na geração de eletricidade em PCH’s, com 49.172kW, ou seja, 41% da potência instalada. Destaca-se por fim que as PCH ‘s não estão automaticamente associadas a impactos ambientais de menor significância ou magnitude, pois são empreendimentos que podem infligir impactos ambientais tanto para um bioma determinado, quanto para as populações humanas, particularmente as populações ribeirinhas atingidas pelas obras e pela formação do reservatório.

    Evaluation of the energy transition in the process of renewable sources expansion - a case study.
    (2021) Anjos, Morjana Moreira dos; Costa, Antonella Lombardi; Pereira, Elizabeth Marques Duarte; Moura, Gustavo Nikolaus Pinto de
    Considering the risks related to energy security and the challenges posed by climate change, this work presents a methodology to investigate energy alternatives to promote an adequate energy transition. Such methodology was applied to a case study, modelling the energy system of the Brazilian State of Minas Gerais to subsidize an energy transition with a view to expanding renewable energies and promoting energy efficiency at the state and municipal levels, as well as combating climate change. Projections, in the 2030-2050 horizon, were made using the tool Long-range Energy Alternatives Planning System (LEAP) to establish a model of energy transition policy for Minas Gerais State. The modelling considered key assumptions based on historical data of demographic and economic origin, which subsidized the elaboration of three scenarios, being a Reference Scenario (REF), a Moderate Energy Transition Scenario (ETM) that aims to contribute to the energy sector goals of the Brazilian NationallyDetermined Contributions – NDC, and an Advanced Energy Transition Scenario (ETA) that goes beyond of NDC's goals. The analysis has shown that current policies are not sufficient to promote the state transition to sustainable energy systems and that this process will depend on the energy policies initiated and implemented in the near future.

    From the development of an open-source energy modelling tool to its application and the creation of communities of practice: The example of OSeMOSYS.
    (2018) Gardumi, Francesco; Shivakumar, Abhishek; Morrison, Robbie; Taliotis, Constantinos; Broad, Oliver; Beltramo, Agnese; Sridharan, Vignesh; Howells, Mark; Hörsch, Jonas; Niet, Taco; Almulla, Youssef; Ramos, Eunice; Burandt, Thorsten; Peña Balderrama, Gabriela; Moura, Gustavo Nikolaus Pinto de; Zepeda, Eduardo; Alfstad, Thomas
    In the last decades, energy modelling has supported energy planning by offering insights into the dynamics between energy access, resource use, and sustainable development. Especially in recent years, there has been an attempt to strengthen the science-policy interface and increase the involvement of society in energy planning processes. This has, both in the EU and worldwide, led to the development of open-source and transparent energy modelling practices. This paper describes the role of an open-source energy modelling tool in the energy planning process and highlights its importance for society. Specifically, it describes the existence and characteristics of the relationship between developing an open-source, freely available tool and its application, dissemination and use for policy making. Using the example of the Open Source energy Modelling System (OSeMOSYS), this work focuses on practices that were established within the community and that made the framework's development and application both relevant and scientifically grounded.

    (2022) Allington, Lucy; Cannone, Carla; Pappis, Ioannis; Barron, Karla Cervantes; Usher, Will; Pye, Steve; Brown, Edward; Howells, Mark; Walker, Miriam Zachau; Ahsan, Aniq; Charbonnier, Flora; Halloran, Claire; Hirmer, Stephanie; Cronin, Jennifer; Taliotis, Constantinos; Sundin, Caroline; Sridharan, Vignesh; Ramos, Eunice; Brinkerink, Maarten; Deane, Paul; Gritsevskyi, Andrii; Moura, Gustavo Nikolaus Pinto de; Rouget, Arnaud; Wogan, David; Barcelona, Edito; Niet, Taco; Rogner, Holger; Bock, Franziska; Quirós Tortós, Jairo; Angulo Paniagua, Jam; Krishnamurthy, Satheesh; Harrison, John; To, Long Seng
    Energy system modeling can be used to develop internallyconsistent quantified scenarios. These provide key insights needed to mobilise finance, understand market development, infrastructure deployment and the associated role of institutions, and generally support improved policymaking. However, access to data is often a barrier to starting energy system modeling, especially in developing countries, thereby causing delays to decision making. Therefore, this article provides data that can be used to create a simple zero-order energy system model for a range of developing countries in Africa, East Asia, and South America, which can act as a starting point for further model development and scenario analysis. The data are collected entirely from publicly available and accessible sources, including the websites and databases of international organisations, journal articles, and existing modeling studies. This means that the datasets can be easily updated based on the latest available information or more detailed and accurate local data. As an example, these data were also used to calibrate a simple energy system model for Kenya using the Open Source Energy Modeling System (OSeMOSYS) and three stylized scenarios (Fossil Future, Least Cost and Net Zero by 2050) for 2020–2050. The assumptions used and the results of these scenarios are presented in the appendix as an illustrative example of what can be done with these data. This simple model can be adapted and further developed by in-country analysts and academics, providing a platform for future work.

    South America power integration, Bolivian electricity export potential and bargaining power : an OSeMOSYS SAMBA approach.
    (2017) Moura, Gustavo Nikolaus Pinto de; Legey, Luiz Fernando Loureiro; Peña Balderrama, Gabriela; Howells, Mark
    Bolivia has plenty of energy resources that can supply not only its own electricity demand but has also the potential to export surplus production to its neighbors in South America. This study presents a comparative analysis of the electricity export potential of Bolivia, considering modeling results carried out by the Bolivian government and those from OSeMOSYS SAMBA - South America Model Base. Four scenarios were modelled from different conceptions of strategic large hydropower combinations. The scenarios comparison highlights the cross-border potential trade between Bolivia and neighboring countries, mainly Brazil. Using a Cooperative Games approach, through the calculation of the Shapley value, the bargaining power of Bolivia was identified, reaching its higher value in the scenario where El Bala and Cachuela Esperanza dams are present. The cooperative games approach provides a better understanding of electricity trade opportunities to support policy makers in international negotiations, thus considerably reducing incentives to non-cooperative actions.
