By early October 2026, Mexico’s electrical grid continued to face significant instability, driven by infrastructure limitations and shifting demand. In Veracruz, where residents previously reported nightly outages due to overloaded transformers, energy specialists warned that rising temperatures and the widespread use of air conditioning are placing further pressure on distribution networks. Additionally, experts noted that the growth of electromobility in Chiapas—specifically the rise of private electric vehicles and corporate fleets—is expected to exacerbate existing overloads unless accompanied by urgent modernization of transmission networks. New disruptions emerged in Monterrey, where the downtown area, including Barrio Antiguo and Barrio de la Luz, suffered repeated failures in CFE supply. By September 28, the region had experienced multiple significant outages, including an 18-hour disruption, a nine-hour failure, and a 28-hour outage on September 20. These failures have heavily impacted local commerce, causing food spoilage, equipment damage, and the temporary closure of businesses. In Tizimín, residents of the La Huayita neighborhood protested after two consecutive nights of outages caused by intense heat. CFE personnel attributed these failures to a transformer lacking sufficient capacity to meet local demand. Meanwhile, in Paseo de San Isidro and Soneto 156, residents reported dangerous electrical failures during rainfall, describing a utility pole that emitted a “loud humming sound, followed by sparks, an explosion, and flames.” By October 3, new service crises emerged in Tijuana, Baja California. Residents of the Mariano Matamoros neighborhood threatened to occupy CFE facilities following a prolonged power outage. Affected citizens reported that the lack of electricity has led to spoiled food and medicine, while high temperatures have caused health issues among minors, including dizziness and vomiting. In Guerrero, the CFE has also been managing infrastructure repairs following meteorological disruptions from Hurricane Polo and Tropical Storm Rachel.
