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 their hydropower
to grow and support the state’s communities and economy.
They’ve led clean energy innovation in Australia - building 55 major dams, 30 hydropower stations and two major wind farms. They employ more than 1,100 people
, mostly in Tasmania.
Hydro Tasmania sells energy into the National Electricity Market through their retail business Momentum Energy
. They also offer world-renowned expertise through their specialist consulting firm Entura
Today, Hydro Tasmania stands ready to help make Tasmania the Battery of the Nation. They have the skills, experience and passion to help create an energy future that’s clean, reliable and affordable
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.
They also part-own two Tasmania wind farms with a combined capacity of 300 megawatts, and own the gas-fired Tamar Valley Power Station in northern Tasmania.
The electricity they 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. They’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 their hydropower system (including with pumped storage hydro), and further developing the state’s world-class wind power, they 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. They’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.
They’re also investigating the possibility of installing an extra smaller turbine at Gordon Power Station (their largest station), to boost efficiency while releasing environmental flows into the Gordon River.
