Description
[What the role is]
The key scope of work for the position is to provide operational support of Energy Management Systems which involves round the clock monitoring and control of electricity generators as well as the electricity and natural gas transmission networks. In addition, the position is also required to operate a Cybersecurity Operation Centre to monitor cybersecurity threats and manage Power Sector Critical Information Infrastructure incidents.[What you will be working on]
Energy Management System (EMS) Operations & Supporting Infrastructure
Provide operational and first-level technical support for the Energy Management System (EMS) to ensure high availability and reliability of power system operations. This includes supporting 24/7 monitoring and control of electricity generation, electricity transmission networks, and natural gas transmission system.
Perform operations and maintenance of EMS platforms, supporting operational technology (OT) systems, and associated OT/IT network and security infrastructure. Investigate and resolve technical issues reported by Power System Operators to ensure continuous and reliable system performance.
Support the enhancement and development of mission-critical EMS capabilities, including the integration of renewable energy resources such as solar power, energy storage systems, and electricity imports.
Assist in maintaining and optimizing power system applications used for real-time operations, such as contingency analysis, transmission network analysis, short circuit analysis, automatic generation control, load forecasting, solar PV forecasting, telemetry systems, state estimation, and dispatcher training simulators.
Coordinate with licensees and stakeholders to facilitate the connection of new generation facilities and transmission equipment. This includes updating and validating EMS databases to ensure alignment between system models, field equipment, and operational requirements.
Support the maintenance and operation of critical infrastructure that enables reliable control centre operations, including uninterruptible power supply (UPS) systems, fire protection systems, and physical security access control systems.
Cybersecurity Monitoring and Incident Management
Provide operational support for the Cybersecurity Operations Centre (CSOC) to monitor and manage cybersecurity threats affecting power system operations and the Power Sector's Critical Information Infrastructure (CII).
Responsibilities include analysing security alerts, identifying anomalies, performing incident triage, and coordinating with relevant stakeholders and CII operators to investigate and resolve cybersecurity incidents.
Cybersecurity Risk Management
Support the implementation of cybersecurity controls and mitigation measures to strengthen the security posture of EMS and related systems in compliance with regulatory requirements, including the Cybersecurity Act and relevant Codes of Practice.
Assist in conducting security reviews, risk assessments, and audits to identify vulnerabilities and security gaps. Support remediation activities such as implementing audit recommendations, performing system patching, and maintaining security documentation.
