Job description
We are currently working with one of our esteemed clients who are looking for a Power Systems Design Engineer to work on EPC – HV Substation & BESS Projects. The role will be based in the clients head office in Glasgow, with site visits if and when required.
This is a full time role and the candidate will report to the Lead Electrical Engineer / Engineering Manager.
Sector: EPC / Power Systems / Energy Storage / Grid Connections
We are seeking an experienced Power System Design Engineer to join our clients 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 Our Client Offers
- 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.
