Cause of Today's Power Failure

The explosion of a transformer substation in Villa Nueva (Guatemala City) caused an almost nationwide blackout today. The failure of the transformer triggered a domino effect as protective devices tripped causing a blackout of almost the entire country, reported the minister of Energy and Mines, Carlos Meany.

The blackout occurred at around 10:50 AM and spread to almost all departments except Quiché and Petén.

Power was restored in Izabal in about 3 hours.

Regarding the electricity interconnection (intertie) between the electrical systems of Guatemala and Mexico, tests that were scheduled for today were postponed until next Tuesday and that the interruption of electrical power was not related to any tests or to the intertie.

The intertie with Mexico will enable Guatemala to obtain as much as 200 megawatts of energy from Mexico, 120 MW is allocated to INDE.
