It's all part of the service at the new, $414 million Stockland Green Hills development.

The new electric car charging stations - there will be four (two Tesla and two Chargepoint) - will be operational when the final stage opens on March 22.

“We know EV vehicles are part of the future and we are excited to be rolling out these facilities,” Stockland Green Hills project director Peter Hugh said. “These will allowing shoppers to plug in for free while they shop or dine.

The charging stations are part of a massive commitment to green energy by the group in recent years.

They have installed 55 free charging facilities in up to 19 locations throughout Australia since 2015, which have been used more than 3,500 times by customers.

But an even bigger green project won’t be ready for the March 22 opening.

They have started installing a $2.8 million rooftop solar project with partner Todae Solar.

The project will see Stockland install 5480 solar panels that will cover a roof area of approximately 27,000 square metres.

The system is expected to generate approximately 2,770,000 kWh of renewable energy per year, which Stockland say will be enough to power 295 homes.

It is expected to be switched on at the end of May.

“We’re extremely proud to be installing this solar project at Stockland Green Hills. It will help create clean, green energy for our retailers, our customers and the community," Mr Hugh said.
