About the Role
We are looking for an experienced Power System Network Model Engineer to support electricity transmission network modelling within an Energy Management System (EMS) environment.
The successful candidate will be responsible for developing, maintaining, and validating detailed network models representing the electrical transmission system. This includes modelling substations, busbars, circuit breakers, transformers, transmission lines, generators, and the connectivity relationships between these assets.
You will work closely with transmission operators, electricity utilities, and/or grid control centre teams to ensure network models accurately represent the physical power system and support real-time monitoring and operational analysis.
Experience with GE PowerOn, GE XA/21, or a comparable transmission EMS platform is highly desirable.
Working Arrangement & Clearance
- SC Cleared: Hybrid working, approximately 2–3 days onsite per week in Wokingham.
- SC Eligible: 5 days onsite per week in Wokingham while clearance is being obtained.
Candidates must be UK-based and remain UK-based for the duration of the assignment.
Candidates must either hold UK SC clearance or be eligible to undergo SC clearance.
Key Responsibilities
- Develop, configure, maintain, and validate electricity transmission network models within an EMS environment.
- Model and maintain electrical assets including:
- Substations
- Busbars
- Circuit breakers
- Transformers
- Transmission lines
- Generators
- Define and maintain accurate network topology and connectivity between electrical assets.
- Ensure the network model accurately reflects the physical transmission network.
- Map SCADA telemetry and live monitoring data to the corresponding network equipment and model elements.
- Support network model validation, testing, and quality assurance.
- Apply knowledge of state estimation, power flow, and contingency analysis to support EMS functionality.
- Investigate and resolve network modelling and connectivity issues.
- Work with control centre, engineering, operational, and technical stakeholders to understand modelling requirements.
- Support network model migration, commissioning, and system upgrades where required.
- Contribute to continuous improvements in network modelling processes and EMS capabilities.
- Ensure models and associated documentation are accurate, consistent, and fit for operational use.
