"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."

Becoming the renewable energy Battery of the Nation

Tasmania has significant potential in the future development of wind and hydropower, coupled with more transmission and interconnection. Tasmania could make a much greater contribution to the National Electricity Market (NEM), delivering more clean, reliable and affordable energy.

It is anticipated these developments will drive billions of dollars in investment and create thousands of jobs in Tasmania, as well as delivering energy security for Tasmania and lowest possible power prices for Tasmanians.

Battery of the Nation is about investigating and developing a pathway of future development opportunities in hydropower system expansion including pumped hydro. Hydro Tasmania is leading work on hydropower system improvements, new pumped hydro opportunities and future market analysis.

The Australian Renewable Energy Agency (ARENA) has supported Battery of the Nation project studies with $5.0 million in funding as part of its Advancing Renewables Program.

Deep storage and its role in a reliable, resilient future energy market

As Australia’s transition to a greater penetration of renewables ramps up, new analysis from Hydro Tasmania examines the role of storage in supporting a reliable, resilient future energy market and shows that Tasmania’s clean energy stacks up as very cost competitive, further validating the case for an expansion of Tasmania’s hydropower system.

Our white papers, jointly funded with the Australian Renewable Energy Agency (ARENA), take a close look at future modelling and design of the energy market, unlocking investment in much-needed storage and how deep storage is the optimal, least-cost choice to manage future uncertainty during this transition.

Positive Marinus Link business case welcomed

Hydro Tasmania welcomes the release of TasNetworks’ latest assessment of a new Bass Strait interconnector.

Hydro Tasmania Chief Executive Officer Steve Davy welcomed the positive business case findings for a 1500 MW Marinus Link, saying Hydro Tasmania stands ready to respond to the needs of the market.

More interconnection will unlock Tasmania’s full renewable energy potential, providing clean, reliable and affordable energy to support a resilient future energy market.

You can read more about the Business Case Assessment and Project Assessment Draft report at the Marinus Link website.

Pumped and primed for a bigger Marinus Link

With a strong portfolio of future pumped hydro energy storage opportunities, Hydro Tasmania welcomes news that TasNetworks is assessing options for Marinus Link to provide up to 1500 MW of new interconnection between Tasmania and the rest of the National Electricity Market (NEM).

More interconnection will unlock Tasmania’s full renewable energy potential, providing clean, reliable and affordable energy to support a resilient future energy market.

Our recently completed pre-feasibility study, jointly funded with the Australian Renewable Energy Agency (ARENA), has identified cost-competitive pumped hydro opportunities, with a combined capacity of 3400 MW.

Working together to achieve a clean energy future

New analysis from Hydro Tasmania shows the Battery of the Nation initiative offers significant potential for Tasmania and Victoria to work together to achieve an affordable, reliable clean energy future.

The white paper, How Battery of the Nation can contribute to Victoria’s energy needs and objectives, shows Tasmania can help Victoria mitigate the risks of early or unexpected coal plan retirement, including high costs and unreliable supply, while supporting its renewable energy ambitions.

We’re pumped to announce our three most promising sites

Tribute_bathymetry-112 resize

Hydro Tasmania has revealed the three sites selected for further investigation into their pumped hydro potential.

The three sites - at Lake Cethana and Lake Rowallan in the North West, and near Tribute Power Station on the West Coast – were selected from the original list of 14 potential pumped hydro options around the State.

They emerged as the most promising from the studies carried out over the last 20 months as part of a $2.0 million study jointly funded by the Australian Renewable Energy Agency (ARENA) and Hydro Tasmania.

Unlocking Tasmania's energy capacity through interconnection

SmHYD Battery of a Nation Icons RGB-HYDRO

Analysis released by Hydro Tasmania demonstrates that additional Bass Strait interconnection would immediately unlock many hundreds of megawatts of latent dispatchable capacity in the Tasmanian hydropower system, and make it available to a transforming National Electricity Market (NEM). 

The White Paper The potential of Tasmania’s renewable generation assets with more interconnection has been developed as part of Hydro Tasmania’s work to support Tasmania’s ambition to become the renewable energy Battery of the Nation.

Becoming the renewable energy Battery of the Nation

With the support of 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

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.

Market analysis

Hydro Tasmania completed the first round of investigation in 2018, 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 available below.

The findings demonstrate that Tasmania can make a significant contribution to the transformation of the NEM in coming years.


Benefits for Tasmania and the nation

Battery of the Nation is a key part of the solution needed to support a national energy market in transition. It will deliver multiple benefits to the state – giving Tasmanians the lowest possible power prices, creating much-needed jobs in regional areas and bringing broad economic benefit to Tasmania.

Australia is going to need huge-scale renewable development in coming years and Battery of the Nation represents one of the most reliable and cost-competitive solutions for meeting Australia’s future energy needs. 

More interconnection will unlock Tasmania’s full renewable energy potential, providing clean, reliable and affordable energy to support a resilient future energy market.
