Protection and Controls Engineer – HV Substations & BESS (EPC Projects) Location: Advance Grid Solutions Glasgow Employment Type: Full-time, Permanent Reports to: Lead Electrical Engineer / Engineering Manager Sector: EPC / Power Systems / Energy Storage / Grid Connections About the Role As a Protection and Controls Engineer, you’ll play a key role in the design and delivery of protection, control, and SCADA systems for our high-voltage substation and battery energy storage (BESS) projects across the UK. You will work within a multi-disciplinary EPC delivery team to develop and integrate protection and control solutions from concept through to commissioning, ensuring safe, reliable, and compliant operation of grid-connected assets. This role requires a solid grounding in electrical protection design, a strong appreciation of the construction and commissioning environment, and the ability to collaborate effectively across engineering, construction, and commissioning disciplines. Key Responsibilities * Lead or support the design and development of protection and control systems for HV substations (11–400 kV) and BESS grid connections. * Prepare, review, and approve protection schematics, SLDs, interlocking diagrams, wiring diagrams, relay setting sheets, and SCADA I/O schedules. * Perform protection coordination, grading studies, and relay settings calculations, ensuring compliance with DNO/TO/NGESO requirements. * Specify and integrate protection relays, control panels, RTUs, and SCADA systems into overall substation and BESS control architectures. * Support factory and site acceptance testing (FAT/SAT), including configuration and testing of relays and control systems. * Collaborate with internal design, procurement, and construction teams to ensure designs are buildable, cost-effective, and compliant with client and grid standards. * Liaise with DNOs, TOs, and NGESO for interface design approvals, grid code compliance, and protection coordination submissions. * Provide technical support during construction and commissioning, resolving design-related issues and ensuring correct implementation of protection and control schemes. * Manage technical documentation and design deliverables within Procore (or equivalent EPC project management platform). * Contribute to continuous improvement of design standards, processes, and project delivery methods. Qualifications and Experience Essential: * Degree (or equivalent) in Electrical or Power Engineering. * Proven experience delivering protection and control designs for HV substations and/or grid-scale BESS projects. * Strong understanding of protection principles, including differential, distance, overcurrent, and earth fault protection schemes. * Proficiency in relay configuration software (e.g., Siemens DIGSI, GE EnerVista, SEL AcSELerator, Schneider Easergy Studio). * Familiarity with SCADA, RTU, and communication protocols (IEC 61850, DNP3, IEC (phone number removed). * Knowledge of National Grid, DNO, and ENA standards. * Experience working in a multi-disciplinary EPC environment, coordinating with civil, mechanical, and commissioning teams. Desirable: * Experience with BESS control systems, including interface design, EMS/PCS integration, and grid compliance testing. * Understanding of functional safety, interlocking logic, and control philosophy documentation. * Working knowledge of Procore or similar digital collaboration tools (e.g., BIM 360, Aconex). * Chartered Engineer (CEng) or working toward professional registration (IET or equivalent). What We Offer * Competitive salary and benefits package. * Opportunity to work on cutting-edge renewable and grid-scale energy projects shaping the UK’s transition to net zero. * Support for professional development, chartership, and technical training. * A collaborative and forward-thinking team culture within a fast-growing EPC business
