By midnight on July 21, 2026, more than 20,681 customers remained without service. Among those still affected, 4,217 customers had been without power for 72 to 84 hours, while another 4,792 customers exceeded 84 continuous hours without electricity. The Technical Quality of Service Standard for Distribution Systems establishes maximum timeframes for service restoration during weather emergencies, which the regulator determined Chilquinta surpassed.
Superintendenta Marta Cabeza stated that field teams continue monitoring restoration efforts while simultaneously initiating enforcement proceedings where regulatory violations appear evident. The regulatory framework requires distribution companies to restore service within specified timeframes and implement all necessary measures to minimize interruption impacts on customers. Cabeza emphasized that collected evidence indicates a significant number of customers remained without power for periods substantially exceeding regulatory limits.
The formal charges initiate an administrative proceeding allowing Chilquinta to present technical documentation and defenses. If the regulator confirms violations during the process, sanctions will be applied according to statutory authority. Chilquinta acknowledged the charges and committed to providing all technical and operational documentation explaining the extraordinary conditions encountered during the emergency. The company cited simultaneous large-scale damage including fallen trees on lines, broken or destabilized poles due to saturated terrain, severed conductors, and difficult-to-access areas requiring complete infrastructure reconstruction before safe energization.
The proceeding tests regulatory enforcement mechanisms for service continuity obligations as distribution infrastructure faces increasing stress from weather events. The outcome will establish precedent for restoration timeline compliance expectations during emergency conditions affecting large customer populations.
