all distribution stations in Peninsular Malaysia. Over 130 online feeder pillars were equipped with IoT devices and connected to the new DN Utility IoT (UIoT) platform. This integration allows DN to access near real-time information on load and low voltage network parameters, significantly improving load management and analytical capabilities. DN become the first utility in the world to adopt the Integration Standard Common Information Model (CIM): IEC 61968/61970 and 62325, which enables both Geospatial Information System and Advanced Distribution Management System to communicate with one another, thereby setting the foundation of more intelligent network management. A common architecture for the transmission and distribution network was developed, harmonising smart grid initiatives across TNB. This strategic collaboration, jointly developed with experts from both Grid and Distribution Network division, ensures the maximisationof benefits across the network through the Smart Green Utility Masterplan. Expansion of Smart Meter Installations: Advancements in Distribution Automation: Implementation of IoT Devices: Adoption of Operation GIS-ADMS Integrated network Model Automation: Harmonisation Across the Network: TENAGA NASIONAL BERHAD Integrated Annual Report 2023 44 Enhancing Operational Excellence Through a Continuous Drive for Excellence The DN division’s commitment to operational excellence was manifested through reductions in distribution losses and maintaining low interruption durations. A steady decline in distribution losses to 5.42% in 2023 from 6.30% in 2019 underscored the division’s effective utilisation of Advanced Metering Infrastructure and its efforts in deterring illegal cryptocurrency mining activities. Such initiatives have contributed significantly to the efficiency and sustainability of the distribution network. Moreover, the division’s ability to keep the System Average Interruption Duration Index at a world-class low of 46.10 minutes in 2023, only marginally higher than the previous year,
