Reimagining the Tarraleah hydropower scheme

Getting the most out of our existing hydropower assets is a key part of the Battery of the Nation initiative. That is because hydropower is the largest source of flexible energy generation and storage in the National Electricity Market (NEM) and it can continue to be the backbone of a stable, reliable future grid.

We're currently looking at the potential to boost its power capacity, operational flexibility and energy output of one of Tasmania's oldest hydropower schemes.

With the support of the Australian Renewable Energy Agency (ARENA), we’re assessing options for reimagining the Tarraleah scheme in the Central Highlands to deliver more renewable power, more flexibly in the future.

About the Tarraleah hydropower scheme

  • The Tarraleah scheme - pictured below – sits at the headwaters of the Derwent hydropower system, and is a very important part of Tasmania’s electricity generation system.
  • It helps regulate water to six other hydropower stations downstream and supplies about 6.5% of Hydro Tasmania’s total annual generation.
