Protection & Control Engineer - HV Substations & BESS (EPC Projects)
Employment Type: Full-time, Permanent
Reports to: Lead Electrical Engineer / Engineering Manager
Sector: EPC | Power Systems | Energy Storage | Grid Connections
About the Role
We are seeking an experienced Protection & Control Engineer to play a key role in the design and delivery of protection, control, and SCADA systems for high-voltage substations and Battery Energy Storage System (BESS) projects across the UK.
Working within a multidisciplinary EPC delivery team, you will develop and integrate protection and control solutions from concept through to commissioning, ensuring the safe, reliable, and compliant operation of grid-connected assets.
This position requires a strong background in electrical protection design, a solid understanding of the construction and commissioning environment, and the ability to collaborate effectively with engineering, construction, procurement, and commissioning teams.
Key Responsibilities
- Lead or support the design and development of protection and control systems for HV substations (11-400kV) and grid-scale BESS projects.
- Produce, review, and approve protection schematics, single-line diagrams (SLDs), interlocking diagrams, wiring diagrams, relay setting calculations, and SCADA I/O schedules.
- Carry out protection coordination studies, grading studies, and relay settings calculations in accordance with DNO, TO, and NGESO requirements.
- Specify and integrate protection relays, control panels, RTUs, and SCADA systems into overall substation and BESS control architectures.
- Support Factory Acceptance Testing (FAT) and Site Acceptance Testing (SAT), including relay configuration and testing activities.
- Work closely with internal engineering, procurement, and construction teams to ensure designs are practical, cost-effective, and compliant with client specifications and industry standards.
- Liaise with DNOs, Transmission Owners (TOs), and NGESO to obtain design approvals, demonstrate Grid Code compliance, and coordinate protection submissions.
- Provide technical support throughout construction and commissioning, resolving design issues and ensuring the correct implementation of protection and control schemes.
- Manage engineering documentation and deliverables using Procore or equivalent EPC project management platforms.
- Contribute to the continual improvement of engineering standards, design processes, and project delivery methodologies.
- Experience with BESS control systems, including EMS/PCS integration, interface design, and Grid Code compliance testing.
- Knowledge of functional safety, interlocking logic, and control philosophy documentation.
- Experience using Procore or similar digital project collaboration platforms such as BIM 360 or Aconex.
- Chartered Engineer (CEng) status, or actively working towards professional registration through the IET or an equivalent institution
What We Offer
- Competitive salary and comprehensive benefits package.
- The opportunity to work on cutting-edge renewable energy, HV infrastructure, and grid-scale BESS projects that are supporting the UK's transition to Net Zero.
- Ongoing investment in professional development, technical training, and chartership support.
- A collaborative, forward-thinking environment within a rapidly growing EPC organisation delivering critical energy infrastructure projects.
