Power Systems Design Engineer - #2178628

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.
