A fault has reportedly occurred in one phase of the Norochcholai Thermal power plant losing about 270 megawatts to the national grid.
Power and Energy Minister Kanchana Wijesekara in a tweet said that the situation can be remedied within five days.
Despite the fault making a heavy impact on the national grid it will not be necessary to extend the power cuts, he added, promising that necessary measures will be taken in managing the power demand.
