⚡ Australia’s Most Powerful Battery Is Now Absorbing Grid Shocks Like a Pro

Australia has just activated a game-changing energy asset — the Waratah Super Battery, now the country’s most powerful battery and the largest energy unit ever connected to the national grid. More than just a storage device, it’s officially operating as a giant “shock absorber” for the electricity system, helping stabilise the grid and boost renewable energy integration across New South Wales.

🔌 What’s the Waratah Super Battery & Why It Matters

Located on the NSW Central Coast, the Waratah Super Battery is being developed by Akaysha Energy and will reach 850 MW power capacity and 1680 MWh storage once fully commissioned. That makes it even more powerful than Queensland’s 750 MW Kogan Creek coal generator — a milestone that signals the shifting balance of power in Australia's energy future.

Even during its early operation, Waratah is playing a critical role in AEMO’s System Integrity Protection Scheme (SIPS). This scheme uses the battery to absorb shocks in the grid, allowing more power from wind and solar to flow into major urban centres like Sydney, Newcastle, and Wollongong, without curtailment.

🔄 The SIPS Scheme: Supercharging Grid Capacity

Under the SIPS contract, the battery must deliver up to 700 MW and 1,400 MWh on demand — though it’s currently delivering half while completing its commissioning tests. Once fully operational by year-end, it will act as a backstop for transmission stability, meaning more renewables can be transported without the need for expensive new powerlines in the short term.

This innovation is critical, especially after delays in grid upgrades and the NSW government’s decision to extend the life of the Eraring coal plant to 2027. Batteries like Waratah help bridge that gap with clean, flexible power.

⚙️ Not Without Challenges: Delays, Bankruptcy & Bold Ambitions

The project hasn’t been smooth sailing. Delays from bad weather, complex engineering, and even the financial troubles of Powin, the battery supplier, have tested the team. But Akaysha’s CEO Nick Carter says they’ve pushed through — calling Waratah “the single biggest connection point by megawatts” and possibly the most powerful battery in the world right now.

Akaysha, backed by BlackRock, isn’t stopping here. They’re also finalising:

• The 150 MW Ulinda Park battery in QLD

• The 400 MW Orana battery (using Tesla Megapacks)

• The 205 MW Brendale battery near Brisbane

Each project uses innovative funding models like revenue swap agreements and virtual tolling, hinting at the growing sophistication of Australia’s clean energy market.

🔋 Big Batteries, Big Impact on the Grid

More batteries delivering grid-support services — like SIPS — could delay or even replace some of the urgent need for expensive new transmission lines. As Carter puts it:

The federal government’s Capacity Investment Scheme, which now aims to support over 14 GW of batteries, is key to enabling this battery-backed future.
