SCADA UPGRADE, ENHANCED OUTAGE MANAGEMENT AND DISTRIBUTION MANAGEMENT SYSTEM CAPABILITIES
NEEDS STATEMENT The need to invest in SCADA systems has multiple factors:
• Our current SCADA system is a sunset product which poses a substantial risk in not being able to manage utilising new technologies on the network in the medium term • Customers’ demands for faster and more granular information about outages also drives the need to invest in better outage management capabilities • Current systems are not well integrated and the current SCADA system has no provision for standardised interfaces given its age • Health & Safety – to ensure all switching and work activities on the network are being executed without incident, permits and competencies can be managed within the system and every switching plan can be checked against the real network status before being executed • With the increasing amount of DERs on the electricity network, the LV network increases in importance. Real time visibility as well as remote operation of the LV network will be of essence to manage changing customer and stakeholder expectations of the network and the new SCADA system must be able to digest and display the information to Vector’s Control Room • DERMS needs to be fully integrated with the new system(s) to achieve the optimal outcome for our customers DERMS combined with Outage Management and real time LV Visibility, will allow us to be able to provide better outage planning utilising DERs as well as managing peaks with DER support, thus ensuring optimal investment from traditional assets.

DESCRIPTION
DISCUSSION OF OPTION
ESTIMATED COST (NPV IF APPLICABLE)
STATUS
Option 1: Business as usual – Keep existing SCADA
Not investing in a new SCADA system will keep manual processes as relevant systems can’t be fully integrated. This leads to data silos and manual work to synchronize data. In addition, the requirements to manage an electricity network today have changed and the current system does not provide this functionality. Especially as it is a sunset product, no further development is being expected. Modern SCADA system combined with Outage Management and DMS functionality that provides standard interfaces and fits into Vector’s Digital Platform ecosystem. These systems will provide capabilities to manage the electricity network and its current requirements.
Rejected
Option 2: Invest in new SCADA/OMS/DMS
