Transpower's notice of grid reconfiguration

The Code provides that Transpower may only permanently reconfigure the grid, if the reconfiguration results in a net benefit as calculated under clause 12.117(2) of the Code.

Roskill

On 20 March 2009, Transpower advised the Commission that it would change the configuration of the grid in the Auckland region by closing the 110kV ‘split’ between Mt Roskill and Hepburn Road substations with effect from 23 March 2009 (or thereabouts).

A copy of the letter dated 20 March 2009 and details of Transpower’s analysis are available below.

Studholme

On 26 November 2009, Transpower advised the Commission that it would change the configuration of the grid in the South Canterbury region by periodically closing the 110kV ‘split’ between Studholme and Timaru substations with effect from December 2009 (or thereabouts).

The Electricity Commission analysed the data provided by Transpower and agreed that it resulted in a net benefit as calculated according to the Rules.
