Endeavour Energy
Endeavour Energy covers Greater Western Sydney, the Illawarra, the Blue Mountains, and the Southern Highlands.
- Penrith, Campbelltown, Liverpool, Fairfield
- Wollongong and the Illawarra
- Blue Mountains and Southern Highlands

Essential Energy
Essential Energy covers regional and rural NSW — the largest geographic area but lower customer density.

- Far North Coast (Lismore, Ballina, Byron Bay)

Which network are you on?
Your electricity bill shows your DNSP. Your postcode generally determines your network, though some postcodes are split between Ausgrid and Endeavour Energy.

- For western Sydney and Hawkesbury work: many sites sit within Endeavour Energy, where Level 2 ASP authorisation is required for contestable connection work.

Why the network matters
Each distributor has its own service rules, forms, outage processes and inspection expectations. Confirming the network early helps avoid redesign, delayed energisation and rework on overhead or underground service upgrades.
Common questions
Which electricity network am I on in NSW?
Check your electricity bill, distributor outage map or network lookup tools. Mackex can also help confirm the network before quoting ASP works.
Do I need a Level 2 ASP for all networks?
Yes, Level 2 ASP work must be completed by an accredited provider authorised for the relevant NSW distributor.
