You will 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.
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.
