Endeavour Energy is the DNSP for western and southwestern NSW — one of Australia’s fastest-growing solar markets due to the large residential housing stock across Penrith, Campbelltown, Wollongong, and surrounding areas.
Endeavour Energy’s Service Territory
Endeavour Energy’s network covers approximately 2.5 million customers across:
- Western Sydney: Penrith, Blacktown, Parramatta, Liverpool, Campbelltown, Camden, Hawkesbury
- Blue Mountains and surrounds: Katoomba, Lithgow, Orange (partly)
- Illawarra: Wollongong, Shellharbour, Kiama
- Southern Highlands: Bowral, Moss Vale, Goulburn
- Hunter (partly): Singleton, Muswellbrook, parts of the Upper Hunter
Boundary with Ausgrid: The Ausgrid/Endeavour Energy boundary runs through the western suburbs. Inner western Sydney (Strathfield, Burwood, Auburn) tends to be Ausgrid; further west (Penrith, Campbelltown) is Endeavour Energy. When in doubt, use Endeavour Energy’s address lookup or check the customer’s electricity bill.
Technical Requirements
Inverter requirements: The inverter must be on the CEC-approved list under AS 4777.2:2020. Standard AS 4777.2 settings apply for most connections.
Documentation required for systems above 5 kW:
- AS 4777.2-compliant inverter datasheet and model confirmation (from CEC list)
- Single-line diagram showing DC array, inverter, and AC connection
- Export limit configuration details (if applicable)
- CEC installer accreditation number
Export limiting: For systems above 10 kW single-phase, export must be limited to 10 kW via inverter export control. The configuration requires a smart meter or CT clamp for real-time monitoring.
Network-Constrained Areas
Endeavour Energy’s rapidly growing outer western Sydney suburbs have seen significant solar uptake, leading to some network hosting capacity constraints:
- Constrained areas: Some feeder areas in outer Penrith, Campbelltown, and Camden growth corridors may have reduced hosting capacity
- Practical impact: Endeavour Energy may impose a lower export limit (e.g., 5 kW instead of 10 kW) for specific constrained feeders
- How to check: Submit the connection application early in the project — Endeavour Energy’s assessment will flag any constraints and advise on the applicable export limit
For installers working extensively in Endeavour Energy’s territory, building a relationship with their connections team is valuable — they can often advise on network hosting capacity for specific suburbs before a formal application is submitted.
Smart Meter Coordination
As with Ausgrid, smart meter installation in NSW is managed by the electricity retailer (under NSW’s metering contestability framework), not the DNSP directly. For systems above 5 kW:
- Confirm with the customer which retailer manages their meter
- Request a smart meter installation from the retailer — timing varies by retailer (typically 2–4 weeks)
- Coordinate the smart meter installation to occur before or concurrent with solar commissioning
- Ensure the inverter’s export monitoring is configured to communicate with the new smart meter before commissioning
Growth Corridor Solar Saturation
Outer western Sydney suburbs in Endeavour Energy’s territory — Penrith, Campbelltown, Camden — have some of the highest solar uptake rates in NSW. While Endeavour Energy’s network generally supports the 10 kW standard export limit, increasing saturation means some feeders may be reclassified. For high-volume installers in these areas, check hosting capacity proactively rather than assuming the standard limit applies.

Frequently Asked Questions
What areas does Endeavour Energy serve?
Western Sydney (Penrith, Campbelltown, Parramatta, Blacktown), Blue Mountains, Illawarra (Wollongong), Southern Highlands, and parts of the Hunter Valley.
What is Endeavour Energy’s export limit?
10 kW for single-phase residential connections (same as Ausgrid). Some constrained network areas may have lower limits — check on application.
How long does approval take?
Approximately 10 business days for standard applications. Larger or constrained area applications take longer.
Do I need a smart meter?
For systems above 5 kW, yes. Arrange the smart meter through the customer’s electricity retailer — not directly through Endeavour Energy.
