INGENIEUR Stage 4: Billing tamper detection, supply automation, smart billing (pre/ post-paid) and Time of Use (TOU) The AMI project will be beneficial to the consumers as well as TNB. As for the RMR system, remote meter reading capability will mitigate consumer premise inaccessibility, “estimated bill” issues and billing errors. Customers will be able to monitor their electricity usage using an inhome display or web portal, thereby providing them with the ability to improve their electricity usage pattern and reduce energy costs. Other benefits like outage notification, post/prepaid options and demand side management will also be available. Future Grid Operations through Smart Grid Smart grid is an electricity grid modernisation programme that relies on communications and IT for monitoring control and management of generation, transmission, distribution, storage and consumption of energy, and enables customer participation. Smart grids aim to achieve: Higher grid reliability, ●● Increased energy efficiency, ●● Improved operational efficiency, ●● Reduced CO2 emissions, and ●● Increased customer participation. ●● TNB is currently formulating a seven-year roadmap to implement smart grid projects that will cover the following main areas: AMI/Smart Meters, ●● Distribution Automation/Distribution ●● Management System, Demand Response, ●● Self-healing rings/Wide area intelligent ●● systems, Distributed energy resources, and ●● Advanced Condition Based Maintenance ●● (TNB Research Sdn Bhd, 2014, pp. 3-72). be addressed during system design stage and continuously monitored to minimise business continuity interruption or disaster. TNB’s preparedness to mitigate cyber security threats or attacks is summarised as follows: All cyber security controls to be in-line ●● with the “Confidentiality, Integrity and Availability” fundamentals. Being certified with ISO/IEC 27001:2005 ●● Information Security Management System (ISMS) for its critical power system infrastructure. Establishing cyber security policy, ●● governance processes, skilled resources, Cyber Security Incident Response Teams (CSIRT), business continuity management, technology such as firewall, Intrusion Detection/Prevention System, Anti-malware/spam/web-defacement, Data Leakage Protection, etc. Participating in annual National Cyber ●● Crisis Exercise to ensure timely response and proper handling of cyber security incidents. Conclusion ICT plays a key role in enabling business to achieve operational excellence in electric power utilities as shown through examples of systems used for asset management, customer service and operations in TNB. Automation and systems based processes are replacing manual processes to increase operational efficiency, enhance asset management, improve supply reliability and provide better customer service. ICT will be increasingly used in the future to support new initiatives such as smart grid/smart meter implementation. Cyber security risks require greater attention and comprehensive treatment in the future with the implementation of these new initiatives. REFERENCES Cyber Security The pervasive use of ICT, especially IP network connections for implementing smart grid/smart meters project increase cyber security risks. Cyber security risks include intrusion, ma
