Benefits of Basslink

Basslink connects the electricity transmission systems of Tasmania and Victoria. The introduction of Basslink meant that Tasmania could participate in the National Electricity Market (NEM). This allows Tasmania to buy or sell power into the NEM.

Basslink has numerous benefits;

  • Enhances security of supply in Tasmania and Victoria
  • It protects Tasmania against the risk of drought-constrained energy shortages
  • Provides Victoria and southern states with secure renewable energy during times of peak demand.
  • Allows Tasmania to participate in the NEM
  • The Basslink frequency controller has reduced frequency deviations in Tasmania and strengthened the Tasmanian electricity system.
  • Basslink Telecoms has broken the Telstra monopoly for wholesale telecommunications in Tasmania.

During the period 1 January 2007 and 31 December 2009 the benefits of Basslink were clearly evidenced during the drought period witnessed by Tasmania. Tasmania imported 5239.14GWh during the period compared with total exports to Victoria of 1260.01GWh. Basslink drought proofed the State during a particularly dry period for Tasmania. The value of Basslink was clearly recognised through various media reports released by the Tasmanian Government, Hydro Tasmania and the people of Tasmania.

Basslink can transmit peak load energy from the Tasmanian hydro and wind generators to meet these peak demands.

Increased Competition and Economic Benefits

By opening up the Australian market to Tasmania, Basslink encourages innovation and investment in capacity in Tasmania, particularly for green, clean wind power.

The increased capacity and security of supply in Tasmania enables that State to seek further investment in high-energy users such as manufacturing.


Basslink enables Victorians and other States to access electricity generated by the substantial renewable energy sources – hydro and wind – from Tasmania. By choosing green‚ electricity, consumers in Victoria offset the amount of the greenhouse gases, such as CO2, that is produced. The bigger marketplace also encourages additional investment in green energy, in particular wind.

A two-and-a-half year Combined Approval and Assessment Process by the Federal, Victorian and Tasmanian Governments set up an independent Joint Advisory Panel (which took over 500 submissions, held 33 days of public hearings and produced 415 page report. The three governments accepted the independent findings without reservations and issued approvals to proceed based on those recommendations.
