Overview

• Roughly 2.26 million users in Yucatán, Campeche and Quintana Roo lost electricity for several hours on Friday afternoon.
• CFE, Sener and CENACE reported that a failure during maintenance led two 230 kV lines between Tabasco Potencia and Escárcega to trip, and a standard reclosing attempt then tripped two 400 kV lines.
• Crews rearmed affected lines and progressively restored service, with authorities reporting full normalization by late evening and continued monitoring of system stability.
• Traffic lights and telecommunications were disrupted across major cities, while hospitals switched to backup power and the IMSS paused non‑critical services until electricity returned.
• Generation units remained available as operators focused on restoring the transmission topology and reviewing procedures to prevent a recurrence.
