Colombia has surpassed 2.2 GW of operational solar power, solidifying its position as one of the countries with the greatest renewable energy growth potential in Latin America and one of the most attractive investment destinations, according to manufacturers across the photovoltaic value chain. This data comes from a new survey by XM, the operator of the National Interconnected System, which reports 405 generation projects currently in the energy mix, with a combined net effective capacity exceeding 21.7 GW. While the majority of the electrical system remains based on hydroelectric and thermal sources, the recent growth in solar photovoltaics has allowed it to surpass 10%. 
The advancement of this technology has been especially accelerated between 2022 and 2024, a period in which 1,800 MW were added to the system.
Of these, 922 MW are in the testing phase. In 2024 alone, 1,393 MW of solar power were added, and so far in 2025, 289 MW of solar power have been connected and are undergoing testing through August. 
A key aspect of XM's analysis is that the report only includes centralized generation, distributed generation, and large-scale self-generation projects. It does not consider small-scale self-generation installations, that is, the universe of residential, commercial, and industrial installations operating outside the wholesale market. Consulting the official website of the 6 GW+ Plan, which does include these, reveals an additional 362.97 MW of installed capacity. Renewable Business Landscape: The XM report shows that more than a dozen companies are leading solar development in Colombia. Enel Colombia is one of the companies with the largest presence, with large-scale solar parks in operation and new developments underway (692 MW). It is followed by Celsia Colombia and AES Colombia , which have incorporated solar power plants into their traditional portfolios and promote integrated generation, storage, and decarbonization strategies. Also noteworthy are companies such as Erco Energía , Greenyellow , Grenergy Renovables , Enerbit , Solarpack , X-Elio , Solecol , Aldesa Solar , Fusión Solar , Solarnet , and Solenium , which have projects in multiple departments and operate under different regulatory frameworks. Wind Power: Wind power generation, meanwhile, continues to have a marginal presence in operational terms: only 41 MW are currently in service, although greater dynamism is expected by 2026 with the commissioning of wind farms in La Guajira, Cesar, and Atlántico. Companies such as Isagen , Acciona Energía , EDPR , and Vestas lead the large-scale wind pipeline, facing challenges related to connecting non-interconnected areas, obtaining social licenses, and ensuring transmission capacity. Zoning : Geographically, solar deployment has allowed for the partial decentralization of power generation.
Although departments such as Antioquia, Cundinamarca and Atlántico concentrate a large part of the country's total installed capacity, solar projects are enabling new energy hubs, with the participation of regional actors and medium-sized developers. 
The transformation of Colombia's power generation fleet is underway, with solar photovoltaics positioning itself as the country's leading non-conventional renewable energy technology. As of June 2025, according to the progress report on generation projects in development, there are 278 solar projects in various stages of development, totaling 3,329 MW, representing more than 50% of the total pipeline. Although only 43 of these are operational, another 85 are in the testing phase and 13 are under construction, anticipating a significant expansion of installed solar capacity in the short and medium term. To sustain this growth, it will be crucial to strengthen regulatory frameworks, streamline connection processes, expand transmission networks, and ensure stable investment conditions for all market participants.
