    Evaluación de alternativas fotovoltaicas para la descarbonización de la generación termoeléctrica en Colombia

    The energy sector is one of the main emitters of greenhouse gases, making its transformation crucial in addressing climate change. In Colombia, although the electricity matrix is primarily based on hydropower, coal-fired plants remain essential to support the system during droughts, especially under El Niño events. This reliance on coal poses a challenge to meeting the country’s climate commitments. This research assesses the feasibility of converting coal-fired power plants into solar photovoltaic generation. The analysis incorporates solar potential in strategic regions, the current conditions of the national electricity system, and international comparative experiences. The results show that, although there is a favorable perception of the energy transition and the use of photovoltaic sources, intermittency emerges as a weakness that affects acceptance and operational reliability. It is concluded that successful transitions require strategic planning, community participation, and labor reconversion to ensure a just transition. Likewise, socioeconomic, cultural, and environmental conditions are decisive for the success of projects. The financial model developed shows that turning coal plants into to large-scale photovoltaic systems (>50 MW) is not currently viable under market conditions, although it improves significantly under scenarios of increased carbon tax and emission reduction certificates. These findings highlight the need for strong public policies and complementary technological solutions to enable the decarbonization of Colombia’s electricity sector.

    Plan de negocios para venta de energía renovable mediante contratos tipo PPA en los departamentos del Cesar, Guajira y Magdalena
    (Universidad EAFIT, 2025) Vaños Rocha, Carlos Ernesto; Uribe de Correa, Beatriz Amparo; Salazar Gómez, Francisco Javier
    This work presents the structuring of a business plan for the sale of renewable energy through Power Purchase Agreement (PPA) contracts in the departments of Cesar, Guajira, and Magdalena, Colombia. The project focuses on promoting the use of self-generation photovoltaic solar systems, facilitating access to clean and sustainable energy without the need for an initial investment by the client. Through an innovative business model based on advanced monitoring and maintenance technologies, the goal is to significantly reduce energy costs for households and businesses in the region. Additionally, a solid financial structure is proposed, including income, cost, depreciation, and investment budgets, as well as a cash flow analysis. This plan aims not only to provide economic benefits to end users but also to contribute to sustainable development and carbon footprint reduction in the area. Finally, the project’s profitability indices are analyzed, highlighting its financial viability and its potential to attract investors interested in renewable energy.
