About Us

We believe in the power of natural thinking.

Since our first hydropower development a century ago, Hydro Tasmania has been a leader in renewable energy development and is Australia’s largest producer of renewable energy.

Today, we use a combination of water and wind power to harness natural energy that we sell on the national grid.

Our company also owns Momentum Energy, our electricity retailer that specialises in providing quality products and services to customers in Australia. Our international consulting business, Entura offers expert power engineering, renewable energy, water and environmental solutions locally, nationally and internationally.

Celebrating 100 years

Hydro Tasmania turned 100 in 2014.

This significant milestone for all Tasmanians was worth recognising and celebrating. Our history goes well beyond the corporate story and is part of the living memory of thousands of workers and their families.

The people who built Tasmania's world-famous hydropower system were the focus of our celebrations.

We continue to invite people with a connection to Hydro Tasmania to share their stories and photos with us. Share your story at hydro100.com.au
