Wholesale Price

Hydro Tasmania seeks to contribute strongly to the Tasmanian community and economy.

Regulated prices

Hydro Tasmania has an obligation to produce the Tasmanian Wholesale Regulated Prices using the legislated methodology in the Wholesale Contract Regulatory Instrument and complemented by the Electricity Wholesale Contract Guideline, both of which are available on the website of the Tasmanian Economic Regulator

To contract with Hydro Tasmanian under the regulated process, you need to meet the requirements of the Instrument and the Guideline. Your application must be prepared using the appropriate template. Hydro Tasmania reserves the right to reject applications that are inconsistent with the template. An example template will help you prepare your application.
