Co-locating equipment on Transpower sites

All customer equipment located on Transpower sites must be documented in the Access and Occupation Licence - also known as the A&O Licence.

The A&O Schedule 6 Licence enables customers to maintain and operate their equipment on Transpower sites.  It is part of the Transmission Agreement which forms part of the Electricity Industry Participation Code.  All applications must be made to:

There are 6 steps to the process:

1. Application

This is made either through the A&O email above or on your behalf (and as agreed) by Transpower's Customer Solutions team, Project or an Engineering Consultant.  The Application must include the AO Questionnaire [ pdf 492.16 KB ]and any documents available at this stage to provide detail of the proposed installation, removal or modification.

2. Approval in principle

The purpose of this stage is to provide confidence to the Customer that Transpower is okay with the works and any potential problems have been flagged.  Transpower's Engineering Consultant is responsible for coordinating the approval process and will liaise with the reviewers (typically 3-8 subject matter experts within Transpower's teams to review an A&O application.  Initial approval is confirmed by an "Approval in Principle" letter to the customer.  This letter will also indicate any further information needed to resolve for the Final Approval Stage.

3. Final approval

Once any  further information requested has been provided the designated Engineering Consultant and the Transpower reviewers assess the information.  If satisfied, Transpower sign off on it, and a final written approval is issued to the customer.

4. Delivery

When the customer receives the final written approval, they can then make the necessary arrangements, including contacting the site Service Delivery Manager, to access the site and complete the work

5. Compliance check

Within 30 business days of the completion of the site works, the Customer must provide Transpower with all the information set out in the Final Approval letter.  Transpower then conducts a compliance check and if everything is in order updates their internal A&O database.  If Transpower doesn't receive the information within the 30 days, the customer and the works become non-compliant.

6. Licence update

As a final step, Transpower updates the A&O Schedule of the Transmission Agreement and provides this to the customer.
