EPM warns blockages in Antioquia could jeopardize 16% of Colombia's energy supply

Empresas Públicas de Medellín (EPM) has warned that potential blockades in the North and Northeast of Antioquia could disrupt operations at five key hydroelectric plants, representing 16% of Colombia's energy demand Source: El Tiempo. The company received reports of imminent protests that would hinder access to the Porce II, Porce III, Guadalupe III, Guadalupe IV, and Troneras plants, which together have a capacity of 1,617 MW Source: La República.

Affected infrastructure

These five plants are critical to the national grid. Porce III leads with 700 MW, followed by Porce II (405 MW), Guadalupe III (270 MW), Guadalupe IV (202 MW), and Troneras (40 MW) Source: Portafolio. EPM has activated security committees with the Ministry of Mines and Energy to coordinate protection Source: El Colombiano.

Additional risks from illegal mining

Compounding the threat, EPM highlighted that unauthorized mining activities in the area have caused hydraulic alterations to the Porce River and endangered infrastructure such as access roads, dams, and tunnels Source: Infobae. These operations increase the risk of landslides and jeopardize both personnel and communities.

Context of El Niño

The warning comes during a period of high stress on the energy system due to the El Niño phenomenon, which has reduced water inflows Source: El Tiempo. EPM's generation manager stressed the need for all plants to operate at full capacity to meet demand Source: El Colombiano.
