Frequently Asked Questions
What is the average electricity bill in NSW?
For a 2-person household in NSW, the average electricity bill is approximately $559/quarter or $2236/year. Costs range from ~$406/quarter for singles to ~$773/quarter for a family of four.
Which network covers my NSW address?
Greater Sydney, the Central Coast, and the Hunter Valley are served by Ausgrid. Western Sydney, the Illawarra, the Blue Mountains, and the South Coast are on the Endeavour Energy network. The network affects your supply charge but not your retailer options — both networks have full retail competition.
Is the NSW Default Market Offer (DMO) a good deal?
The DMO is a reference price set by the AER — it is not the cheapest plan. Many competitive plans undercut the DMO by 10–20%. The DMO is useful as a benchmark to assess whether your current plan is competitive.
