Latin America power outages and grid upgrades

Overview

Heavy rains and extreme heat continue to strain electricity systems across Latin America. In Chile, floods in the San Juan–El Tranque sector left residents without power for more than two days, while rural families in Loncoche endured outages of up to eight days; damaged road embankments forced the closure of the Valiente bridge on route N‑309 and prompted health‑agency counseling for flood‑affected families. The Dominican Republic has pursued extensive grid‑modernisation: utilities have built new substations, installed dozens of transformers and medium‑voltage lines, upgraded public lighting, and launched a RD$518 million sub‑station repowering programme covering 17 sites. Scheduled maintenance caused short‑term outages in several municipalities, and a protest in Sabana Grande de Boyá highlighted resistance to transformer removal. ETED’s contingency plan for the 2026 cyclone season, a 600 MW two‑hour storage project, and the $2.1 bn Hostos HVDC link to Puerto Rico aim to boost resilience, while contracts for 325 MW of renewable generation with battery storage and major transformer deliveries target service for over 900 families. Mexico faces rolling blackouts in more than 20 states as record heat drives air‑conditioner use and overloads ageing transmission assets; protests have erupted in Veracruz and Mexico City, and illegal “diablitos” connections and cable theft compound grid stress. Regional outages have also affected Argentina, Colombia and Cuba, underscoring a continent‑wide need for accelerated infrastructure investment and coordinated emergency response. LED streetlight upgrades have expanded. Puebla, Mexico, completed LED conversion for 184 fixtures serving 3,400 residents; the Dominican Republic’s Edesur installed nearly 10,000 LEDs across 12 jurisdictions; similar projects launched in Venezuela, Argentina and Ecuador to improve safety and cut energy use.
