The Fiji Electricity Authority said the recent power blackout in Viti Levu on Monday was the result of a trip of all four sets of generators at the Wailoa Power Station.
CEO Hasmukh Patel said prior to this event all four generators at the station (Wailoa) were in full operation supplying a total load of 65MW.
"The power blackout occurred at 3.35am on Monday morning," he said.
"The other machine that was in operation before the blackout was at Kinoya Power Station which was supplying a load of 8MW.
"The Kinoya Power Station generator tripped at 3.35am due to a technical problem and the load being supplied by this machine prior to its tripping had to be taken up by the generators at the Wailoa Power Station."
Mr Patel explained that since the generators at Wailoa were running above 85per cent load, these units could not take up this additional load and, as a result all four sets at the Wailoa Power Station tripped causing a Viti Levu power blackout.
He added that by 7am on the same day, the entire Western Division as well as 100per cent of the Central Division had power normalised.
"The FEA has implemented precautionary measures to minimise such outages in Viti Levu and sincerely apologises for any inconvenience caused to all valued customers," Mr Patel added.
