Ausgrid, which supplies power to 1.5 million households and businesses in Sydney, the Central Coast and the Hunter, introduced new seasonal tariffs in 2018.

“Usage rates on the last day of May will be dramatically different on the first day of June,” Compare the Market spokesman Simon Downes told Nine News.
“It’s the worst possible time for households… It’s really going to give you some bill shock.”
From June 1 until August 31, peak usage rates will apply from 5pm to 9pm weekdays.

Applications for the NSW Family Energy Rebate which provides a credit of up to $180 for this financial year close at 11pm on June 16.
