Approval of Augmentation of Electricity Supply Transmission Systems - Tasmania


You may need approval if you are a Transmission Network Service Provider (TNSP) and intend to augment a part of your electricity supply transmission system. TNSPs manage the high voltage lines that transmit electricity to cities, towns and across state borders.

Approval is required if the augmentation:

  • would be required in order for the system to be likely to meet a network performance requirement
  • is proposed in your power system planning
  • has a construction, operation and maintenance cost estimated to exceed $35 million multiplied by the CPI increase since 2013 for the current year.

Transmission systems must meet minimum network performance standards in order to satisfy the regulatory test in the National Electricity Rules. The network performance requirements constitute the service standards that a Provider must comply with when carrying out power system planning for a transmission system.
