NEW CUSTOMER CONNECTIONS
NEEDS STATEMENT Auckland’s population is growing at a rapid rate. The demand for new housing is outstripping available supply resulting in construction of new high density subdivisions in previously greenfields areas (residential subdivisions) or refurbishing and intensification of existing established areas. The connection forecast for the next ten years is shown in Section 2. Vector is keen to support this growth by investing in reinforcing our network to support subdivision reticulation enabling the connection of these new customers (new connections). Commercial growth differs from residential growth by virtue of the size of the load presented to the network and the way in which we deliver the capacity to meet the customer’s needs. The solutions focus more on the installation of substations, whether new (customer substations) or capacity upgrades of existing substations (capacity changes). Smaller commercial customers may be supplied from street reticulation (business subdivisions) much the same as for residential subdivisions. As part of the reticulation we may be asked to install streetlighting circuits. Vector also takes into consideration the changing energy needs of both residential and commercial customers, such as the predicted increase in the number of Electric Vehicles for private and commercial use, in the design of networks for subdivisions.
OPTIONS CONSIDERED The following options are considered for new customer connections.
