A fire at the T&TEC Abattoir Substation along the Eastern Main Road, Port-of-Spain on Tuesday night.

An explosion at a T&TEC substation along the Eastern Main Road in Port-of-Spain caused a blackout in the capital on Tuesday night.

According to reports, a transformer at the substation near the Port-of-Spain Abbatoir exploded just before 7 pm.

This triggered islandwide power dips across Trinidad and the electricity supply for customers supplied from the substation was interrupted.

Several parts of Port-of-Spain were thrown into darkness and the fire could be seen from miles away as firefighters and T&TEC officials tried to address the problem.

Earlier in the day, an electrical fire at the T&TEC Master Substation, located along Park Avenue in Port-of-Spain, near the PowerGen plant, also caused a blackout in the capital between 11.15 am and 1.15 pm. Firefighters from the Wrightson Road Fire Station responded to that fire.
