If your Kings Cross 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 Inner City / CBD.
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 Kings Cross (2011)
In the Inner City / CBD, Kings Cross (2011) is characterised by high-density terraces, heritage buildings and apartment towers with tight street access. Understanding that housing is half the job when it comes to service-side electrical work.
Around Kings Cross we're regularly called out for metering upgrades for apartments and small commercial spaces, underground supply and pit-and-pipe connections in built-up streets and strata and mixed-use switchboards serving several tenancies — all Level 2 ASP work rather than something a general electrician can sign off.
Power to Kings Cross runs through the Ausgrid network. High density and older building services mean metering and connection work here needs careful coordination. Ausgrid feeds the inner city with a dense mix of underground and overhead supply, and access for network work is often constrained.

Do You Need Three Phase in Kings Cross?
Three phase is worth considering at Kings Cross 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.
