About The Battery
How long will it take to build the battery?
How big will it be?
Once completed, the 300MW battery will cover an area similar in size to football oval at Geelong’s GMHBA Stadium.
The battery will look like an enclosure of white containers similar to this digitally rendered image of the future site.
Where will it be located and why?
This land is ideal because it is flat and is next to the high voltage 500KV transmission line which means the power can be sent quickly to where it is needed.
The Victorian Big Battery will support the increasing number of solar and wind projects in Victoria.
What technology will be used?
We will use Tesla Megapacks which have a 20 year lifespan. They retain most of their capacity right up to this point and are often capable of operating beyond this time depending on market conditions and other factors.
How does it work?
The Victorian Big 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?
The project has a service contract with AEMO to provide 250 MW in System Integrity Protection Scheme (SIPS) Services. The services are intended to permit an increased transfer capacity of 250 MW over the Victorian-NSW Interconnector (VNI) at peak times.
We are working in partnership with AusNet who own and operate the Moorabool Terminal Station and the Victorian transmission network.
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
What is SIPS ?
A 250 MW SIPS service contract was awarded to the Victorian Big Battery by AEMO under the Victorian Government’s SIPS 2020 procurement process. Put simply, the scheme enables the additional import of electricity over the Victoria to New South Wales interconnector of up to 250 MW at peak times.
SIPS a mode of operation where the battery has a pre-programmed response to a network failure. When SIPS is triggered by an unforeseen power line failure or generator outage, the battery automatically charges or discharges to prevent a blackout.
Batteries are incredibly well suited to perform this service because they can respond at warp speed. Until recently, large power lines and state interconnectors had to maintain significant headroom to survive major interruptions. In recent years, SIPS from batteries have been used to unlock this capacity like opening up an extra lane on a freeway.
Will local jobs be created?
We will source local suppliers where possible and our partner Ausnet has sourced the power transformers from local business Wilsons Transformer Company.
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.
