Mr Bryant said pensioners and other residents on fixed incomes already struggled to keep the lights on and air conditioners running after a 21.4 per cent increase in 2013-14.

``Obviously for the folk we deal with that will be a very difficult equation to solve,'' he said.

``The frustrating part is if you're able to work you can put in a few extra hours to make up the difference, but here you have to look at what you can cut away to make it happen.'' 

The Queensland Competition Authority  announced this week electricity bills would increase by 13.6 per cent or $192 in 2014-15 if the carbon tax remained and 5.4 per cent $76  if the tax was abolished.

It's the first time the QCA has released two separate estimations to account for the carbon tax, but proved the tax isn't the only thing putting pressure on prices.

``The public image was that the carbon tax was behind all the increases and was the problem,'' Mr Bryant said.

Solar feed-in tariffs and network charges account for about 70 per cent of the ``typical tariff 11'' for residential bills.

Increases in those costs means even if the carbon tax is removed, electricity prices will still go up.

QCA chair Malcom Roberts said not using as much electricity didn't always equate to savings either.

``It may seem strange, but actually reducing the use of the electricity grid, reducing consumption, pushes up the price of the networks,'' he said.

Mr Roberts said ``typical''  households would also find $225 embedded in network charges to pay for the solar feed-in tariff by 2015-16.
