About Us

We believe in the power of natural thinking.

Since our first hydropower development almost 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.
