As strata buildings add lifts, EV charging, larger pumps and air-conditioning, single-phase supply is often no longer enough. Sydney Power Group (SPG) upgrades Sydney strata buildings to three-phase supply, giving the shared infrastructure the capacity to carry modern and future loads.
As a Level 2 ASP authorised across Ausgrid, Endeavour Energy and Essential Energy, we manage the whole upgrade — consumer mains, main switchboard and the network-side connection change. See our related supply upgrade service page for the technical scope.
Why Strata Buildings Go Three-Phase
Three-phase supply delivers more power more efficiently and is often required for lifts, large pumps, air-conditioning plant and shared EV charging. A building running on aged single-phase supply simply cannot support these loads without upgrading.
Moving to three-phase future-proofs the building. It is the enabling step for shared EV charging infrastructure and for spreading load evenly across the scheme so no single phase is overloaded.

A Coordinated Upgrade
A three-phase upgrade touches several parts of the shared infrastructure at once — the consumer mains are usually replaced, the main switchboard reconfigured, and the network connection changed. Each of the network-side steps requires a Level 2 ASP.
We manage the whole project end to end, including the network application and connection works, so the owners corporation deals with one accountable contractor rather than juggling several.

Minimising Disruption
A supply upgrade usually needs a planned outage while the connection is changed over. We plan the disconnect and reconnect carefully with the strata manager, schedule it to suit residents and keep the outage as short as possible.
