ABOUT THE BATTERY
How long will it take to build the battery?
How big will it be?
Where will it be located and why?
The land is ideal because it is flat, in a rather isolated area, and surrounded by trees.
The Great Western Battery will support the increasing number of solar and wind projects in NSW.
What technology will be used?
How does it work?
The Great Western Battery will store energy in times of high production and release energy in times of high demand, similar to how a battery on a home solar system works. It will also help to stabilise the grid in a few different ways – it has an emergency response mode to prevent blackouts and it can maintain voltage and frequency levels.
Who will pay for it?
How will the battery reduce costs for consumers?
- supporting more wind and solar, which are now the cheapest forms of power
- allowing more power to flow into the state, increasing competition and pushing electricity prices down
- helping to avoid blackouts and the associated costs
Will local jobs be created?
We will also provide opportunities for local suppliers, businesses, schools and community groups.
I live nearby – what impact will this have on me?
How will construction impact the surrounding area?
How can I have my say on the project?
We will be working with the community throughout the project to understand local concerns and aspirations, and ensure we minimise any impacts. We encourage the community to provide feedback through completing the survey.
How will the community benefit?
SAFETY & ENVIRONMENT
What approvals are required for the project?
Will the battery increase the risk of fire?
Batteries, like all electrical equipment, require careful design to ensure that fire risk is mitigated and controlled. For the VBB the first line of defence for fire risk is to isolate any problem battery packs and prevent the problem spreading. The tesla megapack battery modules are all individually controlled and require a system-OK signal to remain active. If the signal is lost for any reason, the individual battery packs self-isolate and disconnect from the power inverters. As a secondary line of defence, these battery packs are housed in separate IP rated insulated cabinets that are designed to contain any overheating issues to the affected cabinet only. The battery is also monitored 24hours a day, and we are able to diagnose issues through the control system. As a final line of defence the site has on-site fire-fighting water and equipment.
All of the medium voltage and high voltage cabling associated with the battery is underground, protected from extreme weather and external shorts. Perhaps the biggest fire risk is to the north and east of the battery site, where the existing above-ground high voltage power lines connect the Moorabool substation to customers in the electricity network. Here the battery contribution to fire risk will be positive: the VBB will install lightning conduction structures that will help to reduce the risk of lightening strike on these existing transmission towers.
Are there any health risks?
What happens to the batteries when they reach the end of their life?
After removal, a large percentage of the material in the batteries will be reclaimed or recycled; more than 60% of materials, especially critical minerals, will be recovered for re-use
