Grid Outputs Report 2019

Each year, Transpower publishes a Grid Outputs Report which provides our customers and stakeholders with a summary of the performance of our regulated transmission business over the past disclosure year.

The 2019 report also presents a summary of our service performance and asset health measures, quality standards, targets and incentives the Commerce Commission has determined for RCP3 – the five year regulatory control period starting 1 July 2020.
