New Gungahlin suburb to pioneer big battery as part of Canberra's all-electric future

One of Canberra’s first battery-powered suburbs is a step closer, with the first shovel diving into the dirt for the next stage of Jacka.

Named after Albert Jacka, the first Australian to be decorated with the Victoria Cross during the First World War, the new Gungahlin suburb between Taylor and Bonner is already home to more than 700 people.

Stage 2 will add approximately 700 single residential multi-unit homes and commercial opportunities, plus a nature reserve and local shopping centre.

The headline act, however, is a big community battery powered by the rooftop solar panels the ACT Government will encourage residents to install.

“People will be encouraged to put solar panels on their homes and to store excess electricity in the community battery,” ACT Minister for Housing and Suburban Development Yvette Berry said.

“This will help take us away from fossil fuels and make sure our city can depend on electricity that is sustainably sourced from the sun and wind.”

The Jacka battery project forms part of the government’s plan to grow Canberra’s renewable energy storage sector through its $100 million ‘Big Battery’ project, with help from the Australian National University (ANU). This also includes a proposed 250-megawatt battery built by French company Neoen (also behind South Australia’s ‘Tesla Big Battery’) and 14 smaller batteries at government sites.

“The ACT has become a nation leader on climate action, and now we are making it as easy as possible for Canberra households to benefit from the shift to a low emission technology,” Ms Berry said.

“Building Jacka – one of Canberra’s newest suburbs – as an all-electric, solar-powered suburb will save residents money and set the example of how our future suburbs will be powered.”

Suburban Land Agency (SLA) program director David Thornhill said Jacka’s community battery will be about the size of a small car and provide a minimum of 250 kW upfront capacity.

“Everyone’s excess solar power goes into this when the sun is shining and then everyone can draw off it when needed,” he said.

The project is out for tender, but once a construction company signs on, the exact requirements around size, kilowatt storage, and location will be determined. Mr Thornhill said this assessment will also look at the longevity and recyclability of the battery.

“We don’t want to put infrastructure in and then have to redo it at the end of 10 years.”

The nearby Ginninderry region has also made a name for itself as one of Australia’s most sustainable developments, helped by plans for a 300-megawatt standalone lithium-ion ‘Territory Battery’ about 3 km south of Holt.

This will be able to charge and discharge a total of 600 megawatts per hour (MWh). As the average ACT household consumes 18 kWh (0.018 MWh) each day, this is the equivalent of 400,000 households for two hours.

So far, it has only been trialled over two months in 2021, but construction work is set to begin in about a year, pending development application (DA) approval.

New greenfield developments like Jacka also form part of the ACT Government’s plan to deliver more housing options as Canberra’s population looks set to reach 500,000 by the end of the decade.

“Over the next five years, the government is planning for more land to be available than ever before,” Ms Berry said.

“The government is planning for an increase of around 30,000 dwellings in the ACT over the next five years. This will increase the total housing supply in Canberra from around 180,000 dwellings to around 210,000 dwellings.”

Gungahlin is one of the fastest-growing regions in the ACT and has nearly 90,000 residents. In the past 10 years, the population of Bonner and Casey alone has exploded by more than 300 per cent to 7374 and 6482, respectively.

Gungahlin Community Council (GCC) president Henley Samuel said while the news was exciting, it was important the existing roads and public transport options are brought up to scratch.

“We’re playing a catch-up game and we need to plan ahead,” he said.

“At the moment, we can’t get public transport into Jacka because the roads are too small for buses so they’re having to drop people off outside the suburb. I hope this will be looked into for Jacka too, so the roads will be wider.”

The first blocks for Stage 2 of Jacka will be offered as land for release in 2022-23 as part of the ACT Government’s Indicative Land Release Program.

The construction program for Jacka residential estate starts this month and continues into mid-2024.

What is this thing of posing with a shovel? No wonder things take so long to get done in Canberra. Get with the programme. Get an excavator, a scraper and some bulldozers (not the Scotty type!!!).

Nuclear is what we need.

A genius bureaucracy which unbelievably managed to create a suburb with roads too narrow for the buses run by another arm of the same genius bureaucracy will acquire a big battery that stores Mesmeric electricity.

Over the next five years, the government is planning for more land to be available than ever before,” Ms Berry said.

Riotact should be fact checking false statements like this.

The ACT has Jacka and California has Disneyland where one can “Unleash Your Dreams and
Discover More Disney Magic in Fantasyland”.

How does a suburb get through the planning stages with roads that are too small (narrow) for buses?

Easy; Active Transport.
Walk or ride a push bike everywhere and if it’s a battery powered bike, you’ll be able to top it up at the community battery. 😃

Great unless you are disabled or want to travel down the coast

Canberra’s all electric future is financial pain

StevenGreen311:49 pm 17 Dec 22

Electricity in the ACT is 100% sourced from renewables so we have very stable and relatively low costs compared to the states.

Yeah, let’s go back to horse and buggy – way cheaper!

Rohan – Yeah, let’s go back to horse and buggy – way cheaper!
Well that’s what the Greens want. On second thought, their PETA mates won’t even allow the use of horses, so it will be walking with a wheelbarrow. EVs you say? Look at what Switzerland is doing with energy security (or lack of) at the moment. That’ll be us in a few years

Much like the polished silver shovels they always parade around, Berry has never done any real work, it’s all for show.

Where are the inspectors? She isn’t wearing a hi-vis jacket and a hard-hat on a worksite.

Normal people get fined for that.

was going to say the same thing. my gardening tools are certainly not polished silver

Normal people can’t afford stainless steel polished shovels.
