Abstract
Colombia’s electricity system is highly dependent on hydropower. By 2024, about 64% was produced from hydroelectric power plants and approximately a 29% came from fossil fuel power plants. This reliance makes Colombia vulnerable to severe droughts caused by the El Niño Southern Oscillation phenomenon. During El niño events, low levels of water in hydropower dams lead to use gas and coal power plants to compensate the energy shortage.
This paper presents different technical solutions for achieving a 100% renewable energy electricity system in Colombia, by utilizing the H2RES model to represent the hourly energy balance of wind, solar, and hydro resources. The study also considers the future decommissioning of fossil fuel plants, the role of the reliability charge to ensure the security of supply, and the development of future transmission lines. To reach this objective, a multizonal H2RES model was built clustering power plants into 5 regions: Caribe, East, Southwest, Antioquia, and Northeast. Special attention has been given to intermittent sources such as wind, solar, and hydro; particularly, hydro that have high interannual variability and whose integration shape the power system's supply. To address the Colombian case, various alternative solutions were tested: energy storage in batteries and green hydrogen, energy efficiency measures, and distributed renewable generation.
