ACCC ensures power savings passed on

The competition watchdog is stepping up its efforts to ensure savings from the axing of the carbon tax are passed on to everyone.

The Australian Competition and Consumer Commission has begun monitoring electricity on-sellers that buy power from a power retailer before providing it to customers including apartment blocks, caravan parks and shopping centres.

ACCC chairman Rod Sims said thousands of people accessed electricity through an on-seller.

"Our initial focus was on electricity retailers," he said in a statement.

"Now that these retailers are passing on cost savings to their customers, it is timely to ensure that electricity on-sellers do the same, and pass on those cost savings to their own customers."

After the federal government axed the carbon tax in July, electricity prices fell 5.1 percent in the September quarter.

In August, the ACCC issued notices to 250 energy companies to estimate to their customers how much the removal of the carbon tax would affect prices.

The watchdog's staff have been sifting through data to ensure households are paying less for their electricity.
