As costs reduce and DERs grow in popularity, capacity stranding and the related thinning of the network will mostly impact subtransmission feeders first and progressively zone substations, while DERs themselves will influence the function and operation of distribution feeders (HV & LV) as bidirectional power flows start to create impact. The functional capability of distribution substations will also alter as DER changes power flows and impacts on customers’ service needs. As these implications become clearer, specific strategies will need to be established that reflects the impact of new technology on these major functional elements of our network. Similarly, our network vision has specific implications for each of our AMP asset categories listed in Table 3-1.
Details of Vector’s electricity distribution network assets, how they are defined and key statistics, are provided in Section 4.
3.3 ASSET MANAGEMENT ORGANISATION AND GOVERNANCE Vector’s asset management organisation and our governance structure is shown in Figure 3-1. This structure provides oversight and controls all aspects of our asset management practice. An overview of the asset management responsibilities and governance roles within this structure are set out below.
