cannot be foreseen in advance. An annual provisional budget has been included for HV projects that may arise during the year that need to be carried out with urgency but for which no specific budget has been allocated.
As with the provisional budget for HV projects, we have included a similar non-specific budget for the opportunistic installation of cable ducts for future reinforcement projects. Where we know road reconstruction works will be undertaken and we have forecast future network reinforcement requirements, we will install ducts in anticipation of the future needs. Civil works are the most expensive component of installing cables so by installing ducts during roading alterations we can reduce our overall project cost, and we can avoid the cost, public disruption and adverse PR of future civil works when the reinforcement project is ultimately required. Where these ducting opportunities are foreseen we can include them as stand-alone projects with specific provisional budgets (e.g. City Rail Loop ducts, Warkworth – Wellsford ducts, etc).

OPTIONS CONSIDERED Options are summarised below.
DESCRIPTION
OPTIONS
ESTIMATED COST (NPV IF APPLICABLE)
STATUS
Allow for HV network reinforcement un-foreseen at the time the AMP was prepared
Option 1: Do nothing. Funding for unforeseen HV reinforcement projects would have to be sought from existing budgets already “committed” to existing projects or additional funding sought Option 2: Unspecified HV reinforcement budget - To ensure we carry out necessary network reinforcement for projects that arise during the year Option 1: Do nothing. Loss of opportunity resulting in substantially higher future costs
Rejected
$2.5M (over 10 years)
Selected
Allow for the installation of cable ducts un-foreseen at the time the AMP was prepared
Rejected
Option 2: Unspecified cable duct budget. Prudent installation of ducts in conjunction with other roading works to lower present - day costs, avoiding higher future reinforcement costs

EXPANDING NETWORK MONITORING CAPABILITY
NEEDS STATEMENT The increasing societal dependence on high speed communications, automation (and EV’s,) and computer-based devices across wider aspects of our life is making us increasingly dependent on an uninterrupted supply electricity and lowering our tolerance to outages. To meet this demand, we need to extend our monitoring capability of the network to quickly identify those parts of the network susceptible to overloads which, if not attended to, can lead to outages, and where outages do occur, instigate remedial action to restore power as quickly as possible.
