At the same time, Paraguay confronted a major electrical transmission collapse on February 18, 2026, when lines operating at 220 kV and 500 kV from the Itaipú Binacional hydroelectric plant failed simultaneously around 15:20 local time. This triggered a nationwide blackout heavily impacting Asunción, metropolitan areas, the northern and eastern regions, including Alto Paraná department cities such as Ciudad del Este and Presidente Franco. Several high-capacity substations like Acaray and Jepopyhy were affected, leaving thousands without power. The outage coincided with a heatwave pushing thermal sensations above 40°C, heightening the impact on public services and residential users.
The National Electricity Administration (ANDE) reported working to restore service and investigate failure causes but offered limited real-time detail. Interruptions affected traffic control systems and water supply services, with the state water utility Essap warning of potential potable water delivery interruptions as a direct result of power cuts. Some affected areas saw prolonged outages and intermittent supply, with reports of damaged appliances due to power instability.
This incident is part of a troubling pattern reflected in the region’s broader electrical system fragility. In Paraguay and neighboring areas, infrastructure is operating at or beyond capacity limits, resulting in frequent blackouts and service interruptions. These conditions hamper commercial activities, logistics, and increase social discontent, as seen in similar contexts within the Southern Cone, where heat-driven demand strains aging grids. Addressing these infrastructure weaknesses will be critical to maintaining economic growth and ensuring reliable services amid climatic challenges.
