Initial delivery volumes remain limited. Real-time data from Ecuador’s national grid operator Cenace showed 911 MWh imported by 14:00 on the first day, representing a 65.07 MW average and 1.63 percent of system energy during that period. Instantaneous flows varied significantly, reaching 132 MW at 11:00. The binational interconnection permits transfers up to 450 MW, approximately 10 percent of Ecuador’s peak demand. No official announcement from Colombia’s energy ministry or system operator XM had confirmed technical terms, pricing, committed volumes, or duration by press time.
The resumption arrives as Ecuador confronts severe operational stress. The Mazar reservoir, the country’s second-largest and principal hydroelectric asset, registered 2,123 meters above sea level on October 16, placing it just eight meters above the 2,115-meter critical threshold that constrains plant operations. The absolute minimum level stands at 2,098 meters. Insufficient rainfall has prevented reservoir recovery, forcing hydroelectric facilities to run below recommended parameters.
Ecuador’s government extended mandatory industrial disconnections through October 20, imposing blackouts lasting up to 72 hours on medium- and high-voltage consumers to force reliance on private thermal generation. The measure affects approximately 9,000 enterprises nationwide. Unannounced residential outages occurred between October 13 and 15 in Manabí, Guayas, Santo Domingo, and Pichincha provinces. Noboa confirmed that maintenance operations on the national electrical system would begin October 17 to mitigate distribution network impacts.
Industry associations including the National Chamber of Aquaculture have warned of employment effects and demanded transparency regarding crisis severity. Ecuador experienced blackouts reaching 14 hours daily in mid-September 2024, with the Business Committee estimating economic losses equivalent to 1.4 percent of GDP during the 2023-2024 drought cycle. Grid operator Cenace calculates Ecuador requires an additional 1,391 MW of firm generation capacity to navigate the 2026-2027 dry season.
