Melbourne - Australians in Sydney face
power outages on Friday as an extreme heatwave moves from the
desert interior to the country's most populated city, with
demand straining power supplies.
The anticipated outages, as authorities temporarily suspend
power to selected areas to prevent overload, come just days
after 40,000 homes and businesses lost electricity in the state
of South Australia.
Weather forecaster Olenka Duma said a build-up of heat in
Australia's interior was being pushed to New South Wales state.
"It was like the windows and doors were closed for a long
time, and now a weather front has dragged the hot air here,"
Duma, an official of the Bureau of Meteorology, told Reuters.
The mercury is set to soar above 40 degrees C, with New South Wales set to experience its hottest February
day on record on Saturday.
Australia's energy market operator said on Thursday power
supplies were expected to be tight, with shortfalls anticipated
in the late afternoon in New South Wales and the Australian
Capital Territory.
It was too hot for people to go out, said Ned Qutami, owner
of six mobile ice cream bars in Sydney.
"I'm not doing any business today, I'm just sitting in the
air-conditioning at home," said Qutami, who runs Sydney Ice
Cream & Coffee in the city's beachside eastern suburbs.
"People at the beach are either in the water or heading
home. No one is hanging around to eat ice cream."

The intense heat and power outages have sparked debate over
the country's energy security, after the market operator told
power companies in South Australia on Wednesday to switch off
some customers' power supply for a short spell to manage demand.
South Australia depends on wind for more than a third of its
power supply, and the wind died down at the same time as people
started cranking up air-conditioners.
That was the latest in a string of power disruptions and
electricity price spikes to hit the southern state, including a
state-wide blackout that forced copper mines, smelters and a
steel plant to shut for up to two weeks last September.
The problems have sparked a review of the national
electricity market and energy policy on how to cope with rapid
growth of wind and solar power and the closure of coal-fired
power plants that have been essential for steady supply.
