Mexico's Federal Electricity Commission (CFE) attributed to acts of vandalism the blackout that on the night of August 31 cut power to Yucatán, Quintana Roo, Campeche, and Chiapas. According to the state-owned company's statement, service was fully restored at 3:00 a.m. on September 1, after seven hours of disruptions.
CFE explained that the failure occurred on two 400-kilovolt high-voltage lines, with damage to their insulators, and that specialized personnel were dispatched to the site for repairs, according to Quadratín. The outage partially affected users in all four states, per that report. Energy Secretary Luz Elena González Escobar acknowledged the work of CFE personnel and coordination with state and municipal authorities to address the situation. The incident again focuses attention on the transmission infrastructure serving the country's southeast, a region exposed to weather events at this time of year.
Restoration was gradual: according to El Universal, an initial report from the company indicated that supply had been recovered for 25 percent of affected users, and shortly afterward the company declared service fully restored. CFE itself, in its informational release cited by El Financiero, declared the work concluded at 3:00 a.m. on Tuesday. The episode comes days after the company reported, on August 18, a 37 percent reduction in supply interruptions between January and July 2026 compared with the same period of 2024, equivalent to 159,893 fewer failures, and an improvement in response time from 25 to 7 hours.
The figure carries weight for regional planning: the southeast concentrates long-haul transmission lines and faces the most active part of hurricane season. CFE maintains a preventive maintenance program, according to the company. The evolution of that infrastructure will be an indicator to watch in the coming weeks.
