Interim Operational Guideline for Connection of New Generation Technology

We have published an Interim Guideline for Connection of New Generation Technology to provide guidance  to expedite the entry of grid and distribution network connected new generating technologies into the power system and the wholesale market.

The document sets out the key considerations and obligations when connecting new generation technology to the power system such as engagement with the System Operator and Grid Owner, registration as a participant, metering and operational communication requirements.

This document has been prepared based on the current arrangements and obligations in the Electricity Industry Participation Code, which is subject to review by the Electricity Authority. This document assumes asset owners are familiar with the other Transpower supporting documentation and guidelines, including the Generation Connection Guide [ pdf 468.68 KB ] and the Companion Guide for Commissioning Generation.

Companion Guide for Commissioning Generation

We have published a Companion Guide for Commissioning Generation to assist in identifying all the activities that need to be considered when connecting new generation, and a Memorandum of Understanding to set guiding principles between Asset Owners and Transpower when preparing to build new generation.

The Companion Guide provides guidance on the typical activities that need to be considered when commissioning and testing or decommissioning generation, and the minimum lead times for critical tasks. Additional reference documents are being developed and will be added to this page as they are completed.

The Memorandum of Understanding sets key principles and identifies communications paths to help make the construction and commissioning of new generation a success.
