The Ultimate Off-Grid Mega-Project: Solar, 16GWh Batteries, and the Hyperscale AI Data Centre Pushing the Limits

As the AI boom demands increasingly massive amounts of electricity, the Australian outback is becoming the new frontier for hyperscale digital infrastructure. But one company is pushing the boundaries of what an off-grid energy project looks like.

Singapore-headquartered Energy North has officially submitted plans for Project Ares—a jaw-dropping proposal for the Northern Territory featuring a 1-gigawatt (GW) IT load data centre entirely disconnected from the state grid. To keep the servers running 24/7 without grid support, Energy North is proposing an unprecedented power architecture: 3 GW of solar, a 16-gigawatt-hour (GWh) battery, and 1 GW of gas-fired generation.  

If you are a commercial energy user across Queensland, Victoria, or Western Australia, this project is a massive case study in the extreme lengths developers are going to secure "firm" dispatchable power. Here is what you need to know about the mega-project aiming for the Australian outback.

⚡ Project Ares: The Scale of the Off-Grid Ambition

Located on the massive Murranji Station cattle property—roughly 680 kilometers south of Darwin—Project Ares is designed to be a behind-the-meter fortress of compute power.  

According to the developer's EPBC Act referral, the project aims to bypass the constrained urban electricity grids entirely. The data centre itself will be built in two massive 500 MW phases, ultimately covering 90 hectares. To power it, Energy North intends to cover up to 7,000 hectares with a massive solar array.  

📊 Project Ares Architecture at a Glance

Infrastructure Type	Planned Capacity	Strategic Purpose
Solar Generation	3,000 MW (3 GW)	Primary daytime energy supply; designed to power the facility and charge the massive BESS.
Battery Storage (BESS)	16 Gigawatt-hours (GWh)	Unprecedented deep storage designed to smooth out rapid AI-driven power fluctuations.
Dispatchable Gas	~1,038 MW (1 GW)	"Hydrogen-ready" firming and backup generation for overnight reliability.
IT Load Capacity	1 GW (Tier III Standard)	High-availability compute power targeted at global hyperscale and AI customers.

The Regional Push: Project Ares isn't alone in the Northern Territory. Drawn by subsea fiber-optic cables linking Australia directly with Singapore, there are at least a dozen proponents exploring the region. Even SunCable is actively pitching its massive gigascale solar projects to prospective data centre clients.  

🛑 The Backlash: Firming vs. Fossil Fuels

While the massive solar and battery footprint is impressive, the inclusion of a 1 GW gas power station has triggered immediate pushback.  

Federal guidelines agreed upon by energy ministers require new data centres to "bring their own clean energy." Greenpeace campaigner Solaye Snider heavily criticized the proposal, stating: "This hyperscale project proposes massive new off-grid gas infrastructure, making a mockery of the federal government’s unenforceable ‘expectations’ that data centres will cover their own power use with renewables."  

Energy North defends the gas inclusion as a necessary "firming" mechanism to meet Tier III availability standards (which require fully independent backup power). They claim the gas plant will be "hydrogen-ready," with a framework to transition away from fossil fuels as green hydrogen becomes commercially viable. In fact, Energy North is simultaneously developing "Project Sol"—a proposed 2 GW solar and battery-backed green hydrogen and ammonia facility at the same location.  

📍 What This Means for Commercial Energy Buyers

While Project Ares is an extreme, off-grid hyperscale example, it highlights a universal truth for the modern commercial energy market: Solar alone is not enough. You need firming.

Whether it is 16GWh of batteries in the outback or a 500kWh system in an urban warehouse, securing dispatchable power is the only way to protect your business from grid volatility.

• In Queensland: The sheer scale of proposed AI data centres will inevitably compete for grid capacity. You need a dedicated renewable energy consultant in Queensland to deploy a Behind-the-Meter (BTM) storage solution that protects your operations when grid demand spikes.

• In Perth (WA): Just like Project Ares is isolating itself from the grid to ensure reliability, you can isolate your business from WEM price spikes. Engaging a top-tier renewable energy consultant in Perth ensures you size a commercial battery perfectly to bypass peak evening tariffs.

• Across the Country: Navigating complex energy projects requires expertise. A leading commercial energy consultancy can help you deploy smart building automation and battery hybrids to permanently slash your grid reliance.
