Recommendations regarding application of Grid Investment Test by TransÉnergie US (TEUS)

The Commission engaged TEUS to review how the Grid Investment Test (GIT) would be applied to Transpower’s proposed 400kV upgrade between Otahuhu and Whakamaru, and to make comments and recommendations to the Commission that may help the Commission achieve a successful outcome - one that is perceived as fair and correct by the many stakeholders in the process.

This report provides those comments and recommendations, based on TEUS’ review of documents published by both Transpower and the Electricity Commission, and a meeting with Commissioners and a series of meetings with Commission staff in August 2005.
