Power System Design Engineer - HV Substation & BESS Projects (EPC)

We’re looking for an experienced Power System Design Engineer to join a growing engineering team, supporting the delivery of high-voltage substation and battery energy storage (BESS) projects across the UK.

In this role, you’ll develop the electrical designs and studies that form the foundation of complex EPC projects - ensuring grid-compliant, safe, and reliable operation of HV networks and renewable systems.

You’ll work collaboratively with civil, protection, SCADA, construction, and commissioning teams to deliver designs that are technically robust, cost-effective, and practical to build.

Key Responsibilities

• Lead and deliver electrical design packages for HV substations, grid connections, and BESS projects (typically 11-400 kV).
• Develop SLDs, equipment layouts, cable schedules, interconnection diagrams, and earthing/bonding designs.
• Perform power system studies including load flow, short circuit, protection coordination, harmonic, and stability analysis.
• Support grid connection applications, compliance submissions, and power system modelling for DNO/TO/NGESO interfaces.
• Prepare technical specifications for major electrical equipment (transformers, switchgear, cabling, earthing systems, etc.).
• Liaise with network operators and stakeholders to ensure compliance with Grid Code, G99, ENA, and National Grid standards.
• Provide design support through procurement, construction, and commissioning phases.
• Conduct design reviews, manage deliverables, and maintain quality control via digital project platforms (e.g., Procore or equivalent).
• Collaborate with multidisciplinary engineering teams to ensure fully integrated project designs.
• Mentor junior engineers and contribute to improving internal design processes and technical standards.

About You

Essential:

• Degree (BEng/MEng) in Electrical or Power Engineering.
• 3+ years’ experience in power system design for HV substations, grid connections, or BESS projects.
• Strong understanding of HV/LV electrical systems, grid code compliance, and DNO/TO standards in the UK.
• Skilled in power system modelling software (DIgSILENT PowerFactory, ETAP, PSCAD, IPSA, or similar).
• Familiarity with IEC, ENA, and National Grid specifications.
• Experience working in an EPC or multi-disciplinary engineering environment.

Desirable:

• Understanding of BESS operation, control philosophy, and grid integration.
• Knowledge of functional safety, interlocking logic, and commissioning activities.
• Experience with digital design or project management platforms (Procore, BIM 360, Aconex).
• Chartered Engineer (CEng) or working toward professional registration (IET).

What’s on Offer

• Competitive salary and comprehensive benefits package.
• Exposure to full EPC project lifecycles - from feasibility to commissioning.
• Opportunities to work on some of the UK’s most innovative renewable and grid-scale energy projects.
• Ongoing mentorship, technical training, and chartership support.
• A collaborative, innovative, and forward-thinking team environment.
