In the North West region of Canberra, the Murrumbidgee River meets Ginninderra Creek—the creek whose namesake suburb has become a symbol for sustainable development. And among the ecoconscious novelties on this 1600 hectare site is its lack of gas reticulation; in the wake of Stage One, none will be installed aside from the trunk main into the main commercial centre.
Gininderry opted for rooftop solar energy to generate 40 megawatts when all the rooftops are built – more than the remainder of the ACT blended in contemporary solar generation, says Jessica Stewart, sustainability manager for Riverview Developments, the joint venture firm between the ACT Government and a subsidiary of Corkhill Bros Pty Ltd developing the site. Demand management systems by Reposit, Evergen and Solar Edge administer the rhythm of the power processed.
To further advance sustainable housing, Gininderry provides a front garden landscaping package to house buyers in Strathnairn, the inaugural neighbourhood to be introduced, and where gas has been reticulated, on the condition that they construct to the Gininderry Housing Development Requirements – that precludes gas connection.
Featuring all-electric homes, the neighbourhood also features electric vehicle charging infrastructure, an electric bikeshare plan, and residential and central battery storage. Space is left over to retrofit tomorrow’s technologies into the current properties, that will be four decades in age when the development is finished.
In the suburb called Whitlam, gas reticulation also has been installed in the streets before the homes.
On 17 January 2020, the ACT withdrew the requirement for gas mains in new developments.
While gas was reticulated through Whitlam, the development is asking residents to opt for an all-electric format in $10,000 rebates – informed by lessons and dollar values from Gininderry – and an additional $4000 grant from the ACT government if they put in a household battery.
The suburb of Jacka has suggested centralised battery storage.
Both Whitlam and Jacka’s electric infrastructure is being cultivated in cooperation with Evoenergy to render these innovations operable.
Canberrans strive for innovative, sustainable and low-cost energy solutions—and these moves seem like positive steps in this direction.
