This AMP covers the electricity distribution network in the context of increasing complexity and in a time when electricity consumption is changing rapidly as consumers electrify their lives and adopt non-traditional energy solutions. Our electricity network is an interconnected network that operates as a geographically distributed machine with many interdependent elements. The traditional model of remote generation connected to the transmission grid and then connected to lines companies for the distribution of electricity to ‘end-customers’ is being challenged and will not suffice for the network of the future in which low carbon emissions and sustainability will become key factors and where consumers will require a greater say and become active participants in the production and delivery of energy. Distributed energy resources (DERs) are increasing in our network and assets that form part of the decentralised energy network, distributed generation and our distributed energy resource management system (our information model that documents the grid assets and maintains their status at any point in time), are now included in the asset category table below. While Section 4 and Appendix 6 provide details that align with the Information Disclosure asset categories 1 as per Schedule 11A(iii), the broader AMP is developed in terms of the AMP asset categories shown in Table 3-1. In addition to these principles and objectives, Vector’s asset management practice seeks to accord with the principles of ISO 55001 ( Asset management – Management systems – Requirements ) and reflects a whole of lifecycle approach.
Detailed single line diagrams of our subtransmission network can be supplied to interested persons.
