Transmission Planning Report 2020

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

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 2020 incorporates both the GRR, GEIR and the forecast fault levels, and is part of Transpower's Integrated Transmission Plan suite of documents.
