NSW could face power shortages as temperature rises on energy policy

Market operator Ameo says the state could run out of power on Friday while Coalition and Labor clash over energy policy

New South Wales is facing a possible power blackout on Friday as the state's electricity system struggles to cope with soaring temperatures.

As Coalition and Labor frontbenchers sparred over the latest blackouts in South Australia, the power market operator warned on Thursday that Australia's most populous state will run out of electricity between 3-5pm on Friday unless generators step in with the offer of more supply.
