MORE than half of the promised $550 a year savings from repealing the Carbon Tax may not eventuate, The Climate Institute argues.
Several government frontbenchers have repeatedly claimed consumers will save $550 a year on power bills and passing on savings through other products and services.
But analysis of the claims by the institute has confirmed the savings were more likely to be between $80 and $200 a year.
Institute chief executive John Connor said on Monday even with expected changes to repeal bills by the Palmer United Party, the promised $550 may not come through.
He said the utilities likely covered by the final repeal bills - electricity, gas and water sectors - may not cover the full impacts, and others may not pass on the savings.
"The Senate should take a breather from the confusion on this debate and have a review of the real price impacts of repeal as well as the implications for pollution," Mr Connor said.
