Upper North Island dynamic reactive support investment proposal - archive

On 20 May 2010, Transpower New Zealand Limited (Transpower) submitted to the Commission a reliability investment for approval under rule 13 of section III of part F of the Electricity Governance Rules 2003. The investment was part of the 2009 Grid Upgrade Plan.

Transpower's application

Transpower submitted the Upper North Island Dynamic Reactive Support Investment Proposal as a reliability investment on 20 May 2010. The proposal involved a number of measures to provide dynamic reactive support for the upper North Island. Transpower sought approval of up to $110.2 million for the proposal.

Note that some of the information in Transpower's application has been deleted from the attached proposal documentation because Transpower advised that the information is commercially sensitive and/or has been provided to Transpower under an obligation of confidence.

Opportunity for comment

• provide written comments on Transpower’s proposal; and

• request that the Commission consider alternatives to Transpower’s proposal.

Details of how interested parties could provide comments on the proposal and request the Commission consider alternatives were available on the Commission’s Upper North Island Dynamic Reactive Support Investment Proposal consultation page.

Comments and/or requests were sought by the Commission by 5.00 pm on Monday, 21 June 2010. Six submissions were received.

Public conference

Under rule 15.2 of section III of part F of the Electricity Governance Rules 2003, a designated transmission customer, an authorised representative of parties substantially affected by the Grid Upgrade Plan, or Transpower, may, within 10 working days of the date of publication of the notice of intention (that is, by 5pm on 19 July 2010), request that the Commission hold a public conference if they consider that:
