Consultation

Thanks to all who provided feedback on this consultation - submissions have now been published.

This consultation sought feedback on a Code amendment proposal that would ensure the System Operator has timely access to accurate information about assets connected to the power system.

We propose to amend the Code to:

update and clarify the common quality-related information requirements in the Code, and
incorporate a new system operation document containing technical specifications for the common quality-related information requirements.

The proposal follows on from our consultation Addressing common quality information requirements.

The options will be implemented in a staged approach, allowing us to first address immediate concerns. We will then turn our attention to developing solutions to enable the sharing of common quality-related information between the system operator and Transpower, as a transmission network owner, and with distributors.

We are considering all submissions and plan to publish a decision at the end of 2025.
