"Tasmania is uniquely placed to help lead Australia through its challenging transition towards cleaner sources of energy. Battery of the Nation offers a future that’s clean, reliable and affordable."
- Steve Davy, Hydro Tasmania CEO

Becoming the renewable energy Battery of the Nation

The Battery of the Nation initiative is about investigating and developing a pathway of future development opportunities - wind, hydropower system expansion including pumped hydro and more transmission and interconnection.

Realising this vision would position Tasmania to make a much greater contribution to the National Energy Market (NEM).

As part of this vision, and with the support of Australian Renewable Energy Agency (ARENA) funding, Hydro Tasmania is advancing studies into three areas:

Tasmanian future state NEM analysis

Building and testing models of a future Tasmanian energy landscape and the expanded role Tasmania could play in the future NEM.

Pumped hydro energy storage assessment

Assessing high potential pumped hydro opportunities in Tasmania, to significantly boost the state’s hydropower capacity.

Hydropower system improvement

An assessment of projects that will improve and optimise our existing hydropower generation including the Tarraleah Power Scheme.



Hydro Tasmania has completed the first round of investigation into how Tasmania can tap into its renewable energy potential.  The outcomes of our pumped hydro concept studies and the first stage Future State NEM analysis are now available. 

The findings demonstrate that Tasmania can make a significant contribution to the transformation of the NEM in coming years. It further strengthens the case for more interconnection across Bass Strait, which would also unlock Tasmania’s untapped wind energy potential.


Benefits for Tasmania and the nation

Battery of the Nation is about locking in our island’s energy security and giving Tasmanians the lowest possible power prices. It offers a future that’s clean, reliable and affordable.

Battery of the Nation is not a Hydro Tasmania initiative; it’s a Tasmanian initiative. It’s designed to serve and support our communities, and will involve opportunities and contributions from right across the renewable energy sector.

Modelling shows Battery of the Nation would create billions of dollars of investment and thousands of jobs in regional Tasmania over 10 to 15 years.

Doubling Tasmania’s clean energy would also create a surplus, beyond our own needs, to support mainland Australia. That’s crucial to replace the coal power that’s being phased out.

More interconnection makes all of this viable - allowing Tasmania to get its product to market. Even with the cost of developing further interconnection, our analysis confirms Battery of the Nation is a front-runner that’s extremely competitive and cost-effective.
