Power Systems Design Engineer

Job Description

Job Description – Power System Design Engineer (EPC – HV Substation & BESS Projects) Job Title: Power System Design Engineer 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 We are seeking an experienced Power System Design Engineer to join our Engineering team, supporting the delivery of high-voltage substation and Battery Energy Storage System (BESS) projects across the UK. In this role, you’ll be responsible for developing electrical designs and studies that underpin our EPC projects — ensuring safe, reliable, and grid-compliant operation of complex HV networks and renewable energy systems. You’ll collaborate with multidisciplinary teams (civil, protection, SCADA, construction, and commissioning) to deliver technically excellent, buildable, and cost-effective solutions. Key Responsibilities * Lead and deliver power system design packages for HV substations, grid connections, and BESS projects (typically 11–400 kV). * Develop single line diagrams (SLDs), equipment layouts, cable schedules, interconnection diagrams, and earthing/bonding designs. * Perform power system studies — including load flow, short circuit, protection coordination, harmonic, and dynamic stability analysis. * Support grid connection applications, compliance submissions, and modelling (DNO/TO/NGESO). * Prepare technical specifications for electrical equipment (transformers, switchgear, cables, earthing systems, etc.). * Liaise with DNOs, TOs, and NGESO to ensure compliance with grid code, G99, ENA, and NG standards. * Provide technical support during procurement, construction, and commissioning stages. * Conduct design reviews, ensure adherence to standards and QA processes, and manage deliverables through Procore or equivalent systems. * Work collaboratively with Protection, SCADA, Civil, and Construction Engineers to ensure full design integration. * Mentor junior engineers and support the continuous improvement of design processes and standards. Qualifications and Experience Essential: * Degree (BEng/MEng) in Electrical or Power Engineering. * 3+ years’ experience in power system design within HV substations, grid connections, or BESS projects. * Strong knowledge of HV/LV electrical systems, grid code compliance, and UK DNO/TO standards. * Experience with power system modelling software (e.g., DIgSILENT PowerFactory, ETAP, PSCAD, IPSA). * Familiarity with IEC, ENA, and National Grid specifications. * Experience working in a multi-disciplinary EPC environment. Desirable: * Understanding of BESS operation, control philosophy, and grid integration. * Working knowledge of Procore, BIM 360, or other project management platforms. * Chartered Engineer (CEng) or working toward professional registration (IET). * Familiarity with functional safety, interlocking logic, and commissioning activities. What We Offer * Competitive salary and benefits package. * Exposure to end-to-end EPC project delivery — from feasibility to commissioning. * Opportunity to work on cutting-edge renewable and grid-scale energy projects. * Mentorship and professional development toward chartership (CEng). * Collaborative, innovative, and forward-thinking team culture
