Wind Generation

Wind Generation Investigation Project (Discussion Papers)

During 2007 the System Operator worked with the Electricity Commission on the Wind Generation Investigation Project (WGIP).

The project was to determine what changes to the Electricity Governance Rules and Regulations (EGRs) and industry arrangements would be necessary to accommodate the connection of large scale wind generation in New Zealand. Further work will be done to determine what changes are required to the Electricity Industry Participation Code that supersedes the EGRs.

The investigation looked at the impacts of wind generation on the operation of the New Zealand power system and electricity market, for a specified set of wind generation development scenarios. A number of Implication Analyses are available below.

Wind Generation Investment

Transpower recommend that parties considering wind generation investment in New Zealand (whether likely to be grid connected or not) should contact Transpower as soon as possible to discuss connection and/or asset owner obligations.

The nature of the New Zealand power system (small and islanded) means there are technical requirements for wind generation that can be more onerous than those found in the larger interconnected grids of other countries.

Transpower is keen to help interested parties by providing as much information as possible on these issues. We will treat all inquiries and discussions about future connection as confidential.
