NSW power customers will see their power bills fall 10 percent, more than after the scrapping of the carbon tax, thanks to a landmark regulatory decision that reins in “gold plating” at electricity networks.

The AER decision will force the networks to slash costs to adjust for the slower growth in power demand and lower financing costs. Capital expenditure will be cut by between 35 and 33 percent, compared to what the companies were planning, and operating expenses by between 22 and 35 percent. “The demand for electricity is falling which puts less strain on the networks and requires less investment to provide a reliable supply of energy.
