  • Mexico City
  • Mexico state

In social networks, users reported that several areas and neighborhoods of Mexico City, such as San Pedro de los Pinos, Napoles, Santa Fe, Álamos, Gertrudis Sánchez, Clavería and Azcapotzalco, were affected. In the State of Mexico, municipalities such as Ecatepec, Nezahualcóyotl, Chimalhuacán, Los Reyes and San Martín de las Pirámides were left without electricity.

What was the cause of the blackout in Mexico?

In a joint conference the CFE and the National Center for Energy Control (PRICE), in charge of guaranteeing the supply of electricity, explained that the problem It was due to an imbalance in the National Interconnected System between load and power generation, which caused a loss of approximately 7,500 megawatts (MW).

Electric energy cannot be stored, at the moment it is procured, it is consumed. In the case of this imbalance, we lost power plants, so production dropped and the protection system entered to regain balance and avoid further damage, the authorities explained.

16 conventional power plants went out of operation.

“There were 16 power plants that went out of operation, 16 conventional and together with photovoltaic and wind power plants were 8,934 MW.”

After the event, “safeguard protections” were activated in order to avoid a greater impact.

“After the event, we had a reaction at the national level to review the effects of this failure, we had five line exits, two between Ciudad Victoria, Tamaulipas and Linares, another two lines of 400 between Mazatlán and Tepic, and a line between Durango and Fresnillo. We are making both land and air travel to see the causes of the lines between Tamaulipas and Nuevo León, which is where we believe the problem of this cut begins ”.

Noé Peña Silva, director of CFE Transmission.

100% service is restored

The CFE indicated that, given the failure, “automatic protection schemes were activated in order to minimize a greater risk.”

Together with PRICE, reported on the progress in restoring power and specified that shortly after 4:00 p.m., the service was fully recovered:

At 4:12 p.m. (Central Time), 100% of the affected load was recovered in the National Interconnected System.

IMSS reports zero impacts due to blackout in several states of the country

The Mexican Institute of Social Security reported, regarding the blackout, “there are no registered effects on the Institute’s medical units,” since the facilities have electricity plants that allow continuity of care.
