Transmission Planning Report - July 2017

Transpower regularly publishes a Transmission Planning Report (TPR) which details the grid asset capability over the next 15 years.

We have evolved our TPR this year to include a Grid Enhancement Approach. These new sections, in each regional chapter, provide more detail on active and potential investment investigations, linking the current investigation status to our planning processes and portfolio funding.

The Electricity Industry Participation Code (the Code) requires Transpower to publish the Grid Reliability Report (GRR), Grid Economic Investment Report (GEIR) and the ten year forecast fault levels within defined timeframes. The Transmission Planning Report 2017 incorporates both the GRR, GEIR and the forecast fault levels. We will not be publishing these reports separately in 2017.

The latest Transmission Planning Report is available below, as a complete document or as separate chapters.
