Paul Graham of Empyreal Energy, said many people are unaware air conditioners, pool pumps and hot water systems suck enormous amounts of power during peak times.
“This translates into bigger bills because charges at peak times are a lot higher than off peak,” Mr Graham said.
“People just don’t realise they are paying more at peak times – the worst time to be running high power usage appliances and devices.”
After almost two months of high temperatures, power users are still in for a big surprise.
Mr Graham said using an air conditioner can add 20 per cent to the electricity bill.
“On top of that, families also face a carbon tax increase of up to $24 a month,” he said
“Add that to air conditioner usage and people are looking at bills that will have doubled from this time last year.
“We have heard of bills going from $400 a quarter to over $700; that’s another $1,200 families have to find in already tight budgets.”
The additional charge on the bill is due to a clause in wholesale electricity contracts called the “carbon benchmark addendum”.
Mr Graham said there is a way around huge electricity bills that will save consumers thousands in the long run.
“Saving a few bucks can be as easy as getting the local sparky out,” he said. “An electrician can help switch devices to off peak times.
“People are also looking to solar to reduce their power costs. Before forking out too much, get someone into do a home usage assessment.
“If you have a small house, there is no need to have your roof covered or spend money on something you do not need,” he said.
“You only need to match your current power usage.”
