| Summary: | Abstract Geothermal energy is the energy that is stored inside the earth and which may be used by man either directly (with no transformation) or to generate electricity by means of a geothermal power plant. This article estimates the participation of geothermal energy in Colombia’s electricity market by the year 2025, based on a review of current installed capacity in the country; potential sources of geothermal energy for electric power generation; the existing regulatory framework for projects involving renewable sources, and the geothermal projects currently under development in the national territory. Demand for electricity in Colombia will continue to increase, which implies that new electric power generation projects must be undertaken in order to meet the country’s demand. The conclusion is that geothermal energy is a good alternative to help achieve this objective. By 2025, geothermal sources are expected to generate at least 1400 GWh of electric power per year, equivalent to 1.65% of total electricity estimate demand in Colombia. If the full potential that has been assessed were exploited, generation capacity could reach up to 17,400 GWh/year (equivalent to close to 20% of the country’s demand) by 2025.
