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, switch gear, 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 Power Factory, 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
