Endeavour Energy · South-West Growth Corridor
Underground pit connections and three-phase upgrades across Narellan
Narellan's growth corridors run underground supplies that estate builders sized for handover day, not for the EV chargers and pools arriving now. Thorntek upgrades the connection at the pit or pillar and the switchboard inside as one Level 2 accredited package on the Endeavour Energy network. Pricing is fixed in writing and the network paperwork never becomes your problem.
01
Level 2 work in Narellan, in detail
A three-phase conversion runs new consumer mains from the street pillar, upgrades the metering and rebuilds the switchboard with RCBO safety switches and room for what comes next, every step under our Level 2 accreditation with Endeavour Energy. We repair underground mains faults on pit-fed streets with careful excavation and clean reinstatement. Established homes towards Camden Valley Way get switchboard and supply renewals on the same fixed-quote basis. Builders engage us for temporary site supply and the permanent connection, certificates lodged at both ends.
What we see most in Narellan
When a new-estate home loads up, an undersized single-phase connection shows itself as throttled charging, dipping lights and breakers that trip on summer evenings near the Town Centre. We convert the supply to three-phase, upgrade the metering and rebuild the board in a single scheduled visit.

Local context · South-West Growth Corridor
What's specific about electrical work in this part of Sydney.
Rapid greenfield growth across Camden, Oran Park and Gregory Hills drives heavy connection and mains-upgrade demand on Endeavour's underground network. Active civil works alongside growing road and rail corridors raise the risk of strikes on pits, pillars and conduits.
