Interconnection assets are the high voltage alternating current (HVAC) lines that transport electricity around New Zealand.

They're designed to:

  • create incentives on Transpower, through enforceable service measures, to provide interconnection assets at the capacity ratings required by designated transmission customers and other grid users
  • ensure that Transpower provides information on the capacity of interconnection assets, and their reliability and availability, to enable grid users to monitor the capacity and performance of interconnection assets
  • establish processes for the identification of reliability investments and economic investments, and alternatives to such investments, to ensure efficient decision-making on the use of and upgrades to the grid
  • specify the circumstances in which Transpower may permanently remove interconnection assets from service or reconfigure the grid.
