Lateness in setting of the proposed carbon price will further delay investments to increase Australia's power supply.
ANZ Banking Group global head of utilities infrastructure and government Peter Davis told the Australian Associated Press that the nation's electricity generation assets would fall further behind demand the longer it took for a resolution on price.
"Until such time as we get greater certainty in this marketplace on the price of carbon, we are not going to get much in the way of investment in generation in this country," he said.
"The sooner that we as a country can move towards that, under the right regime, the better off we will all be."
At present, the government is debating the introduction of the carbon price causing further delay in attracting investments.
