Sydney severe heatwave to strike today – with temperatures predicted to soar up to 12C above average

Blackout warnings for households along the east coast have been lowered after coal-fired power station operators withdrew planned outages during a forecast heatwave.

Australia’s energy market operator issued a warning on Monday afternoon and Wednesday about the risk of blackouts in NSW and Queensland, when temperatures could reach 40 degrees Celsius in parts of Sydney.

Increased use of air conditioning and generator repairs at three coal-fired power stations in NSW threaten to knock out the electricity grid in some areas.

“High temperatures and strong electricity demand, combined with some outages, mean tight forecasts for electricity supply in NSW tomorrow and Wednesday afternoon,” an operator spokesperson said.

The power company lowered the warnings late Monday afternoon.

“The previously predicted Lack of Reserve Level 3 has been lowered to a less critical Lack of Reserve Level 2,” a spokesperson said.

“This improvement is largely due to the elimination of transmission disruptions in the region.”

The market operator said it would take “all necessary measures” to boost supply if forecasts deteriorated again.

Sydney is bracing for a heatwave that will last until Wednesday

Aussies will be sweltering in the coming days as the energy regulator warns heatwave conditions in one state could lead to rolling blackouts.

Earlier on Monday, power companies were asked to turn off major electricity users and increase supply across the state.

“AEMO has alerted the energy sector and is working with power plant operators and transmission companies to increase electricity availability,” a spokesperson said.

‘If the market response remains inadequate, AEMO will take action to maintain supply.’

NSW Energy Minister Penny Sharpe said people should look out for each other during the heat peak.

She said the government is monitoring any problems with energy supplies.

“You have to drink water, you have to go to the neighbors and think about whether you have to go out in the middle of the day in the blazing sun,” she said.

‘Do you really have to have all the lights on in the house… does the air conditioning have to be set to 19 degrees? You don’t do that.’

The Bureau of Meteorology issued a heatwave warning in NSW and Queensland on Monday that will last until mid-week.

Temperatures in Sydney’s city center are expected to peak at 33 degrees Celsius on Wednesday and could reach 40 degrees Celsius in the north-west suburbs.

The heatwave is forecast to end on Thursday and Friday, with rainy and stormy conditions likely.

The forecasts follow a week of rising temperatures in Victoria, where parts of Melbourne reached 37 degrees Celsius – well above the November average.
