About Us

Powering generations

Hydro Tasmania is Australia’s leading clean energy business, largest producer of renewable energy, and largest water manager.
For more than a century, Tasmanians have relied on our hydropower to grow and support the state’s communities and economy.
We’ve led clean energy innovation in Australia - building 54 major dams, 30 hydropower stations and two major wind farms. We employ more than 1,100 people, mostly in Tasmania.
Hydro Tasmania sells energy into the National Electricity Market through our retail business Momentum Energy. We also offer world-renowned expertise through our specialist consulting firm Entura.
Today, Hydro Tasmania stands ready to help make Tasmania the Battery of the Nation. We have the skills, experience and passion to help create an energy future that’s clean, reliable and affordable.
We care, we collaborate, we innovate, we achieve. We are powering generations.

Our energy

Every year, Hydro Tasmania produces about 9,000 gigawatt hours (GWh) of clean renewable electricity from hydropower.
That’s enough to power about 900,000 Australian homes and small businesses.
We also part-own two Tasmanian wind farms with a combined capacity of 300 megawatts, and own the gas-fired Tamar Valley Power Station in northern Tasmania.
The electricity we generate is exported to mainland Australia, and traded on the National Energy Market (NEM) via the Basslink undersea cable. During the wet winter months, we’re traditionally a net exporter of electricity. Over summer, when hydropower storages are lower, we’re generally a net importer.

Battery of the Nation

Hydro Tasmania is uniquely placed to help lead Australia through its challenging transition towards cleaner sources of energy. We’re the nation’s largest producer of renewable energy, and have the skills, experience and passion that’s needed.

At the moment, about 80 per cent of Australia’s electricity comes from coal-fired plants that will eventually close. Tasmania currently provides about five per cent of Australia’s energy, and more than 40 per cent of its renewable energy.
By increasing Tasmania’s interconnection, boosting our hydropower system (including with pumped storage hydro), and further developing the state’s world-class wind power, we could grow that contribution significantly.
In particular, Hydro Tasmania is a national expert at integrating renewable energy into the grid in a stable and affordable way. We’ve already done it innovatively and successfully in Tasmania.

Fulfilling Tasmania's clean energy potential

Large storage devices like batteries and pumped storage hydro will become much more important as Australia seeks to replace coal-fired power and get more energy from other sources, including solar and wind.

The Australian Renewable Energy Agency (ARENA) is working with Hydro Tasmania to explore new pumped storage hydro opportunities around the state.
Those projects could deliver up to 2,500 megawatts of pumped storage generation capacity – which would almost double Hydro Tasmania’s current renewable capacity
There are also plans to replace one of Hydro Tasmania’s oldest power stations at Tarraleah with a modern design – potentially boosting production by up to 200 gigawatt hours (GWh) each year, and extending the station’s operating life by 80 years. 
We’re also investigating the possibility of installing an extra smaller turbine at Gordon Power Station (our largest station), to boost efficiency while releasing environmental flows into the Gordon River.

Our consulting business, Entura delivers clever solutions in water and energy to clients locally, nationally and internationally.
