Network Development Plan The network development plan is fundamental in meeting the forecast demand over the planning period. It is expected that our development projects will continue to drive our lifecycle plans as existing assets are upgraded to meet demand. Network development in response to growth helps us to replace outdated technology by replacing assets that are not intelligent enough or assets that are too highly loaded. We have identified a number of zone substation and network constraints likely to occur throughout the planning period. The most pressing of these are the lack of capacity for growth in the Woodend and Pegasus town areas, at MainPower’s Southbrook substation, and at MainPower’s Mouse Point substation (Culverden). The Southbrook and Woodend area constraints have been managed for some years through incremental distribution upgrades to enable load transfers to surrounding areas. The potential for such upgrades is diminishing and if load continues to grow a major zone substation build will soon be required. Planning for the new substation including land acquisition, 66kV (Kilovolt) feeder source and routes, is continuing. The potential piping of the Amuri irrigation scheme has created further uncertainty about the need for, and timing, of a capacity upgrade at Culverden. Planning for the upgrade is continuing in order to minimise the lead time should an upgrade be required. Partial purcha ͔
