Water price information

Hydro Tasmania is Australia’s largest water manager. While providing clean, secure and affordable hydropower is our main focus, we also take pride in supporting other water users and considering their needs.

We transfer water rights to irrigators and other social and commercial operators, including extra water at times when we can not use it.

Users pay Hydro Tasmania a fee for some water transfers. That fee is based on the revenue Hydro Tasmania would have earned (i.e. foregone revenue) if the water had been used to generate hydropower, and is re-calculated annually based on market factors.

For this new water year (commencing 1 July 2018), instead of using a 5 year averaging approach we will be averaging the water fee over 10 years. The 10 year average will further smooth price changes year on year.

This change is in addition to the change we made in 2017 to use the average Tasmanian Regulated electricity prices as the input to the water fee calculator instead of the Victorian electricity market prices.

These prices only apply to long-term water transfer agreements. The fee for one-off or short term agreements is calculated using the prevailing electricity price.

Please note: all water transfers are subject to any additional terms and conditions that might be required by the Department of Primary Industries, Parks, Water and Environment (DPIPWE).

* 10-year rolling average does not apply to schemes that have energy market exposure through mini-hydro schemes (for example the Midlands Irrigation Scheme). These schemes are able to offset changes in electricity prices via the revenues they earn by operating their own mini-hydro power station.
