WGV | GEN Y House Energy Trading


White Gum Valley Estate (WGV) is a modern, sustainable residential development in the City of Fremantle, Western Australia that is an Innovation through Demonstration project.

With more Australians living under strata title, the 100 dwelling medium density precinct features cutting edge energy-saving initiatives that reduces resident’s living expenses, such as shared solar photovoltaic and storage systems, energy trading between residents and a shared electric vehicle. WGV aims to demonstrate how strata developers can achieve an 80% reduction in grid sourced energy and 70% reduction in mains water consumption through a shared utility governance model which is scalable for national application.

Nestled within WGV is the Gen Y house, a ‘living laboratory’ showcasing millennial inspired sustainable living.
