The Queensland government will finally act on a 2009 recommendation to introduce a variable charging regime for electricity, depending on when it's used.
It's hoped the new 'time of use' tariff will ease demand for electricity during peak periods.
By using power-hungry appliances in low demand periods, consumers will save money on their bills and ease pressure on power infrastructure.
The Queensland Competition Authority recommended the voluntary time-of-use tariff in late 2009, as an alternative to standard metering.
On Wednesday, Energy Minister Stephen Robertson will write to the authority, directing it to establish the time of use tariff, under a new 'cost-reflective' structure to be introduced from July 1 next year, The Courier-Mail reports.
Under the voluntary plan, households will be required to install smart meters, which can adjust tariff prices at different times of the day.
