What's that about?
The business has been a significant part of life in Tasmania for almost 100 years and we plan to continue to play our part in the State’s growth and further development for another 100 years.
Hydro Tasmania is a complex and varied business. Not only do we generate renewable energy and trade in the National Electricity Market, we are the country’s leading clean energy business and the largest water manager in Australia. We also have an extensive professional services business known as Entura and a mainland-based retail arm Momentum. We are building wind farms and developing technology to bring renewable energy solutions to remote areas. Find out more about us >
So it’s not uncommon for our people to be asked about what we do. “What’s that about?” or “What does all that actually mean?”
We want to try and answer these complex questions in a simple way, so click the questions below to find the fact sheets. We will try to keep the majority of fact sheets to no more than two pages.

- How much do lake levels vary?
Hydropower lakes change level because water is used to spin turbines to make power. In this way, water flows in and out of the lakes we operate for hydropower.
