Are you being force-fed more electricity than you need?
Richard McIndoe, who used to run Energy Australia, investigated the high power usage in his home, and what he found was shocking.
"I was getting up once every three or four months to change light globes," he told 7.30. "And this is what led me to look at voltage.
I'm being force-fed more electricity than I need."
He found that the grid was delivering electricity at 254 volts — just above the allowable voltage limit.
"Based on the 254 volts I'm getting here, I'm roughly paying about $1200 more for my electricity each year than I need to," he said.
"We have a major issue with regulating voltage across Australia. And it's getting worse."
After finding the cause of his high power bills, he created a company that filters out extra voltage, to help others save wasted power and money spent of oversupply.
According to the ABC, the nominal voltage for Australian households is 230 volts, but because voltage fluctuates all the time, electricity should be delivered within an allowable range of between 216 and 253 volts.
For households in much of Australia, electricity is supplied with voltage towards the top end of that range and even just above the 253-volt limit.
Depending on the appliances in your home, that can mean greater electricity consumption and bigger power bills.
