Queensland and other state governments are being urged to remove or devalue so called gold plating from electrical transmission networks, by The Australian Competition and Consumer Commission.

That would include a voluntary government write-down of the regulatory asset base in Queensland, Tasmania and for Essential Energy in NSW, and use of rebates on network charges in NSW.

It was estimated the write-downs and rebates could result in savings of $100 a year for the average residential customer.

It is estimated network charges, or "pole and wires", make up about 40 per cent of household electricity bills.
