Investigations are still ongoing into the cause of fires which ignited at two substations in Port of Spain on Tuesday.
The first fire was reported just before midday, at Power Gen, Stone Street, while the second was reported later that night on Abbatoir Road.
The power outage resulting from the fire during the day caused traffic jams on some streets.
At about 11.20 am workers at Power Gen reported seeing smoke coming from the substation. Fire and safety officers responded and, just after midday, the blaze was doused.
Corporate Communications manager Annabelle Brasnell said while investigations are ongoing, the two fires had no relation to each other or other dips in power experienced earlier in the month.
Brasnell explained that the network which provides electricity in PoS is divided into grids, therefore interruptions in service that may be experienced in one area would have nothing to do with interruptions in other areas.
On May 7 a bush fire and a large tree triggered dips in power in Central, East and North Trinidad.
In a release sent to the media, Brasnell said the fire and the tree triggered a fail-safe in the system which saw a dip in power rather than a power outage.
