If your Oyster Bay property keeps hitting its limit, a three phase upgrade delivers the extra capacity that modern homes and businesses need. SPG carries out single-to-three-phase upgrades right across Sutherland Shire.
It's Level 2 work — the supply, consumer mains and switchboard all have to be upgraded and coordinated with Ausgrid, which is exactly what we do.
Three Phase Power Upgrade in Oyster Bay (2225)
In the Sutherland Shire, Oyster Bay (2225) is characterised by coastal beach suburbs and established family homes backing onto bushland and the Royal National Park. Understanding that housing is half the job when it comes to service-side electrical work.
Around Oyster Bay we're regularly called out for salt-air corrosion near the coast and bushfire-zone service lines inland, private poles on bush and waterfront blocks and storm-damaged overhead lines — all Level 2 ASP work rather than something a general electrician can sign off.
Power to Oyster Bay runs through the Ausgrid network. Coastal weather near Cronulla and bushfire risk near the national park both drive service-line and pole work here. Ausgrid supplies the Sutherland Shire, largely overhead, and bush-interface blocks often depend on private poles.
Do You Need Three Phase in Oyster Bay?
Three phase is worth considering at Oyster Bay properties running high loads — ducted air conditioning, multiple EV chargers, large solar and battery systems, workshops, or commercial equipment. It spreads load across three supplies for more headroom and smoother running.
We'll assess your current and future load and advise whether an upgrade is warranted — see our supply upgrade service.

Three Phase Power Upgrade Oyster Bay — Frequently Asked Questions
Why do Oyster Bay properties often need this kind of work?
