The Queensland Government has given evidence at a budget estimates hearing that suggests electricity customers should not fear higher power bills.

Power companies Energex and Ergon are seeking more revenue, but the Government says it won’t come from users.

The big distributors are calling on the Australian Energy Regulator to let them collect $2.2 billion more than the $17.6 billion currently approved for the next five years.

Energex Chief Executive Terry Effeney says the companies want to fix an error made by the regulator in calculating the cost of capital for its draft determination.

“Energex is in a position that it doesn't agree with the AER's position on this matter and has put in a higher WACC (Weighted Average Cost of Capital) than was allowed for in the interim determination,” he said.

Energy Minister Mark Bailey the companies wanted a correction of $1 billion dollars less than the one sought by the previous government.

“I am confident that the regulator has a clear priority in terms of better outcomes for consumers,” he said.

Energex and Ergon said they expected stable or decreasing prices as a result.

“As our revised submission requests lower revenues [than previous years], you could expect to see real reductions to customers in network pricing across this [five year] period,” Mr Effeney said.
