In April, the Australian Energy Regulator (AER) slashed the budgets for Illawarra's Endeavour Energy, as well as other providers Ausgrid and Essential Energy.

The 28 per cent budget cut to Endeavour would equate to an average household bill reduction in the Illawarra of $106 in 2015-16.

Members of the Baird government praised the decision because it would lead to lower electricity prices.

However, Networks NSW, which runs the government-owned electricity networks, has said it will appeal the AER decision and potentially place the level of those power bill cuts in jeopardy. The three networks will not appeal the $731 million in cuts to capital expenditure.

"We will, however, appeal the average annual cuts of $324 million to operating expenditure due to the impact on vegetation and bushfire risk mitigation programs across the state and the AER's decision not to provide a workable transition plan to implement continuing efficiency improvements," Networks NSW chief executive Vince Graham said.

Mr Ward, who is also parliamentary secretary for the Illawarra, said he could not say what effect Network NSW's appeal would have on those lowered electricity prices.

"I don't have a crystal ball so I don't know what the decision's going to be," Mr Ward said.

"That will have to be something we muse over when a decision is made. I want to see lower power prices for people in this area.

"I want to make sure we do everything we can to ensure efficiencies and economies in the network that drive down prices.

"But we also need a safe and reliable network that maintains a consistent supply," he said.
