Update 2: Switchgear blast leads to widespread power cuts
Widespread power cuts were reported in several areas around Malta and Gozo after the distribution switchgear of the Marsa south distribution centre blew up during re-enforcement works.
No one was injured but a number of employees were sent to hospital for observation. Power was restored by 6.45pm.
Enemalta said the fault caused the two units at Marsa Power Station - Turbine 6 and Turbine 7 - together with the steam units and gas turbine at Delimara Power Station to trip.
The only generating units that did not suffer a trip were the diesel engines at the Delimara extension.
As a result, 55 per cent of the island suffered a power cut.
The corporation said investigations are underway to find the cause of the explosion.
