monitoring systems across all zone substations - this includes replacing the core infrastructure for these systems. The intention is to bring all zone substations up to the same standard to ensure that operationally and functionally they are the same. This improves operational familiarity and maintenance requirements. Our security system improvement will also involve the installation of improved and more secure fencing and gating as and where required with a focus on zone substations that supply critical loads e.g. the fuel depot in Wiri. In certain instances, as and where warranted and required, we will install cameras for remote monitoring – an initiative that will also apply to more strategic zone substations that supply critical load.

STATUS
Option 1: Do nothing
Our fire and security systems in a number of zone substations are reaching end of life and is not supported technically any longer. A ‘Do nothing’ approach will put zone substations and its equipment at risk and this option is rejected Although zone substations fires are rare their consequences are very serious. End of life fire and security systems must be replaced to ensure the continued safety of our zone substations. To be able to integrate and manage all security and fire monitoring systems, core infrastructure has been deployed which will also need to be upgraded to comply with latest Cyber Security requirements.
Rejected
Option 2: Undertake a programme of replacing fire and security systems in zone substations Upgrade of core infrastructure for security and fire monitoring

5.1.2 CUSTOMER CONNECTIONS The interface with the customer is managed by Vector’s Customer Excellence Team. Requests for new connections or changes to existing connections are forwarded to the Customer Excellence Team from our FSPs for small projects and from developers or consultants for subdivision and customer substation works. Provisional budgets are then developed. Work on customer connections also include the connection (and disconnection) of smaller customers to Vector’s network as well as minor extensions to the LV mains to allow connection and installation of service pillars. The service main inside the customer’s property is the responsibility of the customer. Activities also include the livening of the service on receipt of a Certificate of Compliance. Expenditure on each service is variable depending on the complexity and scope of the works to be carried out. For the purposes of estimating the budget for the investment summary the average cost of a connection has been applied to the expected connection numbers for the year and regulatory period.
