Media release: New battery to help Tarneit share the sun

23 August, 2021

A community battery to support the growth of rooftop solar will be installed in Melbourne’s west by electricity distributor Powercor as part of the Victorian Government’s Neighbourhood Battery Initiative.

Under the plan, Powercor will install a 150kW/388kWh battery in Tarneit that will allow customers to share their rooftop solar with others, reduce emissions and make the most of the strong local rooftop solar penetration in the area.

The battery is designed to soak up excess rooftop solar generation and supply up to 150 nearby homes during peak periods, allowing the neighbourhood to share in the benefits of solar and more than two and a half hours battery storage.

The Victorian Government will contribute $800,000 towards the cost of battery project.

Powercor’s General Manager, Electricity Networks, Mark Clarke, welcomed the Victorian Government’s funding and support for the project.

“This battery will provide benefits for local customers, whether they have solar or not, by providing the community with access to local renewable energy, improving the reliability of electricity during peak demand times,” Mr Clarke said.

“Solar is booming in Tarneit and this battery will allow more homes to connect and export excess solar from their systems back into the grid.”

Tarneit and the surrounding suburbs have the highest number of solar connections in the Powercor network. In the 3029 postcode (Tarneit, Hoppers Crossing and Truganina), more than 13,800 customers have connected solar to the network, making up about 42% of all customers in the area.

It’s expected the new battery will enable an additional 121,800kWh of solar exports per annum in the area.

Once installed, Powercor will also trial innovative tariffs to allow retailers to offer new products to customers and this project will help shape how community batteries may play a broader role in Victoria’s clean energy future.

Powercor also thanked key supporters of the project, the Western Alliance for Greenhouse Action and Wyndham City Council, which have been instrumental in pushing for community energy options in the western suburbs.

Work will now begin with the community and Council as well as retail partner, Simply Energy, to develop the plan to rollout the technology in Tarneit.

Construction of the new battery is expected to begin this year and expected to be operational by June 2022.
