As a Power System Network Model Engineer, you will be responsible for developing, maintaining and validating Transmission EMS Network Models, ensuring accurate representation of substations, transmission assets, network topology, connectivity, telemetry and operational equipment.

You will support critical EMS applications including Network Topology Processing, State Estimation, Power Flow, Contingency Analysis and Real-Time Operations.

Key Responsibilities

• Develop, maintain and enhance Transmission EMS Network Models.
• Create and manage device relationships across substations, busbars, circuit breakers, transformers, transmission lines, generators and other network assets.
• Build and maintain accurate connectivity and topology models.
• Validate network models and perform data integrity and quality assurance checks.
• Support modelling for new commissioning, network changes and asset updates.
• Ensure consistency between EMS, SCADA, GIS, Asset Management and Planning systems.
• Analyse and resolve model discrepancies affecting EMS applications.
• Support State Estimator, Network Topology Processor, Power Flow and Contingency Analysis functions.
• Participate in network model migrations, system upgrades and integration activities.
• Develop technical documentation, modelling standards and operational procedures.
• Support model governance, audit readiness and compliance activities.
• Manage customer and stakeholder relationships effectively.

Key Skills & Experience

• Strong experience in Transmission EMS Network Modelling and Power System Applications.
• Expertise in device relationship creation and network connectivity modelling.
• Strong understanding of:
  • Transmission network topology
  • Substation configurations
  • Network connectivity
  • State Estimation
  • Load Flow and Contingency Analysis
  • Operational power system principles
• Experience with EMS platforms such as GE PowerOn or GE XA/21.
• Knowledge of IEC CIM standards (IEC 61970/61968) and model exchange processes.
• Experience with SCADA point-to-device mapping and telemetry modelling.
• Understanding of databases, SQL and XML.
• Experience with automation scripting, preferably Python.
• Strong communication and stakeholder management skills.
• Ability to identify and communicate project risks while managing changing priorities.

Experience Required

• Bachelor?s or Master?s degree in Electrical Engineering, Power Systems Engineering or a related discipline.
• 8+ years' experience in Power System Network Modelling, EMS Applications or Utility Operational Technology.
• Experience working with Transmission System Operators (TSOs), Independent System Operators (ISOs), utilities or control centres.

This is a great opportunity for an experienced EMS Network Modelling specialist to contribute to complex transmission network projects and support the systems underpinning real-time power system operations.
