Siebel
Siebel is Vector’s Customer Relationship Management system. This system is used for managing customer requests for new connections, quality of supply complaints management, and fault and outage management Gentrack provides records for all connected ICP’s as well as their regulatory and market attributes. It is used to manage energy consumption, revenue assurance and interfaces with the Electricity Authority registry This is a bespoke integration layer that provides reporting, monitoring and associated analytics related to network assets. It is a critical source of information for most of Vector’s asset management processes This is Vector’s SCADA system and is used to monitor and control operations on the network as well provide data on network loading and other critical asset data ARM is Vector’s corporate risk management system. Under the Corporate Risk Policy all asset management risks are recorded, prioritised and managed through this system. A supporting system, RIMS is used to record any associated incidents Stationware is Vector’s system to record and manage all protection settings in its primary and distribution networks

OTHER IMPORTANT SYSTEMS Vector uses a number of other information systems, computer models and computer based tools in the management of is electricity distribution assets. In particular: • DERMS: a Distributed Energy Resource Management System, this application is constantly processing and optimising the use of any DERs connected to it. This optimises asset utilisation through, for example, peak management via community battery storage and ripple control. The system has a 24 hour load forecast across the overall network down to a distribution feeder and will automatically dispatch DERs to overcome network constraints and minimise customer impact. As more DERs are connected the importance of and reliance on this system will increase • OSIsoft PI: is a real-time network performance management system that utilises data from various corporate systems (e.g. SCADA – see above), and provides a Microsoft EXCEL link to support analysis. This tool provides a permanent archive of historical network data • Forecast Scenario Model: this is bespoke load forecasting model used in Vector’s load forecasting practice. It is implemented in Microsoft EXCEL and draws data from other corporate systems and databases and third party sources • Backstop model: this is a bespoke model implemented in Microsoft EXCEL. It is used in Vector’s network planning practice to forecast the ability to backstop a zone substation in the event of failure of the subtransmission supply; • Digsilent: is a network modelling tool that provides network power flow and fault levels analysis. It uses information from Gentrack and Smallworld to maintain its network model • CYMCAP: is a software tool that calculates cable ratings based on ground thermal conductivity test results and standardised cable installation practices. It is used to set the ratings of all subtransmission cables • HV Spec: is Vector’s system of record for all outage information, including fault interruption and duration data. This system is used to calculate and report on Vector’s reliability measures such as SAIDI and SAIFI • Rating Datasheets: this is a Microsoft EXCEL based database that contains summer and winter ratings for subtransmission plant and considers network pinch points. It is manually updated on an annual basis • Ion: Centralised server for data gathering all power quality metering information from zone substations and GXPs • Zone Substation Equipment Ratings: this is a Microsoft EXCEL based database that contains details of the ratings of primary plant in our zone substations and in GXPs. It considers N-1 ratings for winter and summer conditions and identifies points of constraint. It is manually updated on an annual basis 3.9 DATA AND INFORMATION MANAGEMENT Vector has taken a coordinated approach to the management and governance of its information and data assets. The following four capabilities have been aggregated into a single centre of excellence reflecting the operational, strategic and governance overlaps across the disaggregated functions.
A description of the tools used and strategic approach for each capability is detailed in Section 4.
Enterprise Information Management: This function establishes and administers the data management and governance frameworks applicable to both physical and electronic data and information. In addition, this function oversees the
