Residents of a 32-home all-electric development in Wollert in Melbourne’s north can expect to cut their electricity bills in half thanks to rooftop solar and a precinct-wide microgrid.

The Villawood Properties development, delivered by Metricon, will be serviced by a microgrid, which is a self-sufficient energy system that will allow renewable energy generated on the 36 homes and residents’ club to be shared.

Provided by energy generator and retailer Energy Australia, the geographically discrete energy system is managed by an intelligent microgrid platform that controls the energy flow across the precinct. 

The microgrid will be supported by a 100kW/270kWh battery system and any excess renewable energy generated by the 210kW (total) system will be fed back into the grid.

Each home in the Solstice precinct in Wollert will be equipped with a 3-4kW system and a home energy control system that will optimise the airconditioning and appliances to run off cheap clean energy when the sun is shining. 

As well as reducing emissions, the self-sufficient microgrid will also protect the community from blackouts and instability in the grid. 

All homes will be gas free and equipped with electric appliances, including induction cooking. While the microgrid will reduce reliance on fossil fuel-generated energy, the precinct will not be powered by 100 per cent renewal energy and will need to draw on non-renewable energy from the grid at times.

  1. an obvious benefit for new builds

    I’ve been seeking similar for retrofitting existing inner-city housing – but smaller roofs and multi-unit multi-owner buildings have less suitable roof space for solar and more headaches seeking approval

    I’m thinking obvious places to add massive solar panels is over carparks and shopping centres or industrial warehouses – that’s where I’d like to see installations in these already-built environments.
