AIS/GIS substations
and grid connections, focusing on projects from
33kV to 400kV . You will act as a technical authority, mentor junior engineers, and collaborate with clients and stakeholders to ensure designs meet regulatory standards and project goals. Responsibilities Lead
primary plant design
and
equipment specifications
for new substations, extensions, and upgrades (AIS/GIS) up to 400kV. Produce and review technical deliverables, including
single-line diagrams (SLDs) ,
layouts ,
equipment plans ,
technical specifications , and
design calculations . Oversee
load calculations ,
short-circuit studies ,
dynamic force calculations , and
cable rating designs . Ensure compliance with
UK DNO/TO standards
(e.g., National Grid, SSEN) and
CDM regulations , managing design risks and health and safety considerations. Collaborate across disciplines, including civil, structural, and protection and control, to deliver fully integrated solutions. Actively develop and maintain relationships with clients, contractors, and suppliers. Support project delivery to meet quality, cost, and schedule requirements, including attending client and site meetings. Provide technical leadership, mentoring, and coaching to junior engineers. Take responsibility for quality assurance and ensure compliance with industry standards and best practices. Key Deliverables Substation Primary Plant Design : Develop layouts, plant specifications, and equipment designs for transformers, switchgear, busbars, CTs, VT configurations, and ancillary systems. Design Documentation : Deliver technical reports, design intent documents, risk assessments, and tender documentation. Site Surveys and Constructability : Perform site visits to assess design feasibility and address constructability issues. Interface Management : Coordinate with protection and control, civil/structural and HV cables teams. The Skills
Essential Skills Degree in
Electrical Engineering
or related field. Chartered Engineer
(or working towards chartership). Proven experience in
primary plant design
for HV/EHV substations (AIS/GIS) up to
400kV . Proficiency in producing designs compliant with
UK DNO/TO standards . Knowledge of
dynamic force calculations ,
earthing design , and
plant clearances . Expertise in technical specifications for transformers, switchgear, battery systems, and CT/VT selection. Demonstrable leadership and mentoring skills, with experience managing multidisciplinary teams. Desirable Skills Proficiency in
power system analysis software
(e.g., DIgSILENT PowerFactory, ETAP). Experience with
AutoCAD
for layout and schematic design. Familiarity with
European Grid Codes , grid compliance studies, and
protection and control interfaces . Understanding of
