How would you like to never worry about rising energy prices?
This will soon be the reality for a handful of Fremantle families who will call the East Village.
In what was billed as a first Australian, the development has its own microreadle that uses the energy generated by solar panels stored in a mega battery.
That will mean families will have their electricity bills halved, saving families about $ 1200 a year, according to the developer.
The Smart City is a creation of Power Ledge and Landcorp.
Typically, people sell energy from their solar panels back to the grid at a flat rate, which is selling to other customers at a higher price.
But this system allows households to sell excess solar energy directly to their neighbors for a better rate.
Dr. Jemma Green, from Power Ledge, said it worked as a website.
"It produces an invoice similar to your electricity bill and facilitates the payments associated with it, but it's directly between the buyer and the seller," she said.
In case the battery stops working, the houses will not be left in the dark. The site is connected to the main grid.
The venture will also recycle rainwater, which means an 80 percent reduction in water consumption by Water Corporation families.
