Powerlink‘s Greenbank Substation has taken delivery of a massive 326-tonne transformer for its latest grid-scale battery connection project.

The huge transformer was transported just over 61km from Port of Brisbane to Greenbank on two twelve-axle trailers. It was pushed an pulled by two prime movers on a total of 232 wheels.
The transformer, with a total operational weight is the equivalent of roughly eight Boeing 737 jets, will convert high-voltage electricity to a lower voltage to charge the battery, then send electricity on to customers across South East Queensland.
The Greenbank Substation site was chosen for its strategic location on Powerlink’s transmission network. A battery at this location will allow Powerlink to increase the network capability by ensuring a reliable supply of high-voltage electricity is maintained to South East Queensland.
Powerlink signed an agreement with CS Energy to install a grid-scale battery at Powerlink’s existing Greenbank Substation.
As part of this work, Powerlink will be connecting the 200MW/400WMh battery to the Greenbank Substation, which supplies electricity to South East Queensland—in particular the Gold Coast, Logan and South Brisbane areas.
The battery will have capacity to power 28,000 homes for two hours before needing to recharge.
