The Niue Power Corporation has started rationing electricity on the island, turning supply off for six hour periods.
The NPC said the issue comes down to a lack of power generation at the Power House and the corporation is down to one engine generating supply to the whole island.
The NPC said the engine can only provide power up to 470 Kilowatts.
The company said demand exceeded that level, leading to the decision to turn off power on the north side of the island from 5pm to 11pm last night and then 11pm until 5am this morning on the south side.
Niue Power said they are looking at a better solution and apologise but power cuts are inevitable.
