Our connection process

Transpower's connection process adapts to fit the needs of your connection.  A large complex connection might take over 3 years, a small discrete and simple connection might take less than 18 months.  Our connections process diagram provides a matrix of timing based on your connection.


Concept Assessment Requests

We encourage our customers to contact us directly in the first instance so we can discuss your needs and general Transpower connection considerations. After this, when you are ready to request a concept assessment contact us and we will send you a Concept Assessment questionnaire to complete and if applicable a Transpower Services Agreement.  Once we have the information we need and your agreement to any charges, we will allocate your request to our subject matter experts for assessment.

Turnaround times for Concept Assessments vary depending on the level of customer enquiry.  Transpower's standard turnaround time from concept assessments of average complexity is 25 working days during low levels of enquiry, 35 working days during medium levels of enquiry and 45 working days during high levels of enquiry.  Indicative enquiry levels can be seen on the indicator below. This indicator is updated monthly and enquiry levels at the time of your request may vary from that shown.

Note - the volume shown above indicates Transpower workload relating to Grid connection requests, it does not indicate the volume of commissioning work Transpower is processing as System Operator.

Response times will be longer for very complex requests.  We will discuss this with you directly if applicable.
