Heavy rains and extreme heat have continued 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 lasting of up to eight days; damaged road embankments forced the closure of the Valiente bridge on route N‑309 and prompted health‑agency counseling programmes for flood‑affected families. In the The Dominican Republic, a wave of grid‑modernisation projects Republic has unfolded. Utilities Edeeste, Edesur, ETED, EDEESTE, and EDENORTE pursued extensive grid‑modernisation: utilities have built new substations (La Caleta, La Caleta, La Caleta, Los Minas, La Caleta, Higüey, Montecristi), 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 has caused short‑term outages in Santo Domingo Este, Azua, Barahona and other several municipalities, while and a community protest in Sabana Grande de Boyá highlighted local 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 increase resilience. The sector also awarded boost resilience, while contracts for 325 MW of renewable generation with battery storage and announced major transformer deliveries to improve target service for over 900 families. Mexico has faced faces rolling blackouts in more than 20 states as record heat drives air‑conditioner use and overloads ageing transmission assets. Protests assets; protests have erupted in Veracruz and Mexico City, while lawmakers propose special climate‑linked tariffs and subsidies to cushion households. Illegal illegal “diablitos” connections and cable theft have compounded compound grid stress. Regional outages have spread to Argentina (storm‑damaged lines near Concordia, Salto Grande remained online), also affected Argentina, Colombia (rain‑induced damage repaired by Afinia), Cuba (nightly protests over blackouts), and other Latin‑American locales, Cuba, underscoring a continent‑wide need for accelerated infrastructure investment, storage capacity, 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.
