Australia’s Largest Battery Now Protecting NSW Grid From Blackouts
Affiliate Disclosure
Hey fellow impactful ninja ?
You may have noticed that Impactful Ninja is all about providing helpful information to make a positive impact on the world and society. And that we love to link back to where we found all the information for each of our posts.
Most of these links are informational-based for you to check out their primary sources with one click.
But some of these links are so-called "affiliate links" to products that we recommend.
Why do we add these product links?
First and foremost, because we believe that they add value to you. For example, when we wrote a post about the environmental impact of long showers, we came across an EPA recommendation to use WaterSense showerheads. So we linked to where you can find them. Or, for many of our posts, we also link to our favorite books on that topic so that you can get a much more holistic overview than one single blog post could provide.
And when there is an affiliate program for these products, we sign up for it. For example, as Amazon Associates, we earn from qualifying purchases.
What do these affiliate links mean for you?
First, and most importantly, we still only recommend products that we believe add value for you.
When you buy something through one of our affiliate links, we may earn a small commission - but at no additional costs to you.
And when you buy something through a link that is not an affiliate link, we won’t receive any commission but we’ll still be happy to have helped you.
What do these affiliate links mean for us?
When we find products that we believe add value to you and the seller has an affiliate program, we sign up for it.
When you buy something through one of our affiliate links, we may earn a small commission (at no extra costs to you).
And at this point in time, all money is reinvested in sharing the most helpful content with you. This includes all operating costs for running this site and the content creation itself.
What does this mean for me personally?
You may have noticed by the way Impactful Ninja is operated that money is not the driving factor behind it. It is a passion project of mine and I love to share helpful information with you to make a positive impact on the world and society. However, it's a project in that I invest a lot of time and also quite some money.
Eventually, my dream is to one day turn this passion project into my full-time job and provide even more helpful information. But that's still a long time to go.

📰 The quick summary: Australia’s largest battery is now operating as a shock absorber to prevent power outages in New South Wales, helping stabilize the grid and potentially lower electricity prices.
📈 One key stat: The 350MW Waratah Super Battery can store as much energy as half of the Eraring coal-fired power station, enabling more renewable energy to enter the grid.
💬 One key quote: “The battery system monitors 36 transmission lines in real time across NSW, detects overloading and responds in seconds to increase generation.”
1️⃣ The big picture: Australia’s largest battery system has officially come online as a safeguard against power outages in New South Wales. The Waratah Super Battery, built on a former coal plant site on the Central Coast, now acts as a shock absorber that activates during emergencies like bushfires or lightning strikes to stabilize the energy grid. With 350MW of capacity already operational and plans to reach 850MW by the end of 2025, the battery represents a crucial step in Australia’s energy transition. This technology enables greater utilization of existing transmission infrastructure while supporting more renewable energy projects.
2️⃣ Why is this good news: The battery system dramatically improves grid resilience by responding to disruptions within seconds, preventing blackouts that could affect millions of homes and businesses. By increasing the capacity of existing transmission lines, it reduces the immediate need for costly new infrastructure development. The system helps facilitate more renewable energy projects by providing crucial grid stability as coal plants retire. Electricity prices should stabilize and eventually decrease as more wind and solar connect to the grid with battery backup. The battery’s location on a former coal plant site also represents effective land reuse in the clean energy transition.
3️⃣ What’s next: The battery will continue expanding toward its full 850MW capacity by the end of 2025. More similar systems are under construction across Australia, including at Eraring and former coal plant Liddell. Battery technology investments will continue accelerating as additional coal plants retire in coming years.
