State Electric Company Ltd (STELCO) said that the power outages of Sunday morning were caused after the eight megawatt generators, which were newly incorporated to the power grid, shut down.
STELCO Director Ibrahim Rauf said the new generators shut down due to a technical issue, but had not elaborated on specifics.
Power went out around 2.00am Sunday and resumed at around 4.45am.
Rauf added that power outages were expected as some generators were being tested as well.
