The Hidroituango reservoir has reached level 416 meters, a critical milestone in Colombia’s strategy to secure energy stability against the impending El Niño phenomenon. This progress marks a significant recovery from recent drought conditions that severely impacted water flow in the Cauca River.
Historically, the Cauca River provided between 400 and 500 cubic meters per second of water flow. However, severe droughts recently reduced this to just 250 cubic meters per second, forcing Empresas Públicas de Medellín (EPM) to temporarily halt electricity generation at the facility. To mitigate financial losses during this period, EPM purchased massive amounts of energy from the market, straining its budget while waiting for rains to return. Thanks to increased precipitation in late September and October, the reservoir level climbed from 408 to 416 meters, demonstrating effective operational management despite below-average rainfall in Antioquia.
The primary objective is to reach level 420 meters by July 2027, as authorized by the National Authority of Environmental Licenses (ANLA). John Maya, EPM’s general manager, indicated that the remaining four meters could be achieved within a month if current weather patterns persist. While El Tiempo notes that reaching this height is essential for national energy security, El Colombiano highlights that the reservoir might fill completely before December, ahead of the most severe phase of El Niño expected later in 2026.
This megaproject is part of a wider contingency plan involving conservation campaigns across Antioquia. The urgency is heightened by parallel issues, such as partial water cuts in Medellín due to low levels at the Piedras Blancas reservoir. As EPM balances financial constraints with operational needs, the successful filling of Hidroituango remains pivotal for shielding the country from climate-induced energy shortages.
