Lower household power bills should result from falling energy production costs which have almost halved in the past year.

The Australian Energy Regulator's latest report, released on Friday, shows the wholesale price drop of up to 48 per cent has been driven by record low demand, especially in South Australia and Victoria, due to warm weather and extra rooftop solar power.
Energy and Emissions Reduction Minister Angus Taylor expects power companies to pass on the lower prices to consumers.
"COVID-19 continues to impact households and businesses, so any reduction in energy prices across eastern Australia is welcome relief," he said.
On October 11, South Australia reached a new record low for energy demand, needing just 318 megawatts of electricity from the grid.
That's about one-sixth of the electricity produced by a power station such as Liddell in NSW.
In the three months up to October, Australia's national electricity market produced less electricity than the same period last year, and gas generation was lower in most states, while limits on delivering electricity interstate also affected prices.
The regulator's report found demand for energy is so low that the short-term electricity markets are seeing record levels of "negative pricing" - when generators have to pay the market operator to stay online.
Throughout September, there were negative power prices in at least one Australian state more than eighty per cent of the time during the middle of the day.
With Victoria's COVID-19 lockdown reducing morning peak energy use, the state also saw record low demand for power on several days in late winter and early spring.
Coal-generated electricity was available at lower prices than a year ago, driven by lower fuel costs and increased competition from gas-fired generation and renewables.
"Sustained low wholesale electricity prices translate over time into lower retail prices for businesses and households," regulator chair Clare Savage said.
Meanwhile, gas companies met with the federal government on Thursday, following the introduction of the government's so-called "big stick" energy price legislation in June.
