Senior Electrical Design Manager– Substations & Transmission (HV/EHV)
Voltage Levels: 132 kV / 220 kV / 400 kV
Systems: AIS & GIS Substations, EHV Transmission Lines
Job Description
The Senior Electrical Design Engineer will be responsible for end-to-end primary design engineering, technical evaluation, and cost estimation for HV/EHV substations and transmission line projects. The role involves close coordination with multidisciplinary teams, compliance with international standards, and technical support through bidding, execution, and commissioning stages.
Key Responsibilities
- Substation Primary Design Engineering
- Develop and deliver primary plant designs for AIS and GIS substations up to 400 kV, including equipment layouts and elevations, busbar configurations, cable routing and trench layouts, and earthing and grounding systems.
- Prepare detailed engineering deliverables such as Single Line Diagrams (SLDs), layout and elevation drawings, earthing design and calculations, short‑circuit and electrical stress calculations, and clearance/creepage/phase separation studies.
- Protection, Control & Secondary Systems Interface
- Coordinate relay, metering, and protection scheme design, including coordination studies, trip logic and interlocking philosophy.
- Standards, Safety & Compliance
- Ensure all designs comply with client and utility requirements and international and national standards (IEC, IEEE, BS EN, IS).
- Apply Safety by Design principles and HSE requirements throughout all design stages.
- Design Coordination & Stakeholder Engagement
- Coordinate with civil, structural, protection & control, secondary systems, and transmission line engineering teams.
- Liaise with clients, consultants, suppliers, and internal stakeholders to resolve technical queries and optimize designs.
- Design Review & Quality Assurance
- Review designs prepared by contractors or junior engineers for accuracy, completeness, and compliance.
- Participate in design reviews, technical audits, and hazard identification workshops, addressing risks and mitigation measures.
- Cost Estimation & Tender Engineering
- Prepare detailed cost estimates for 400 kV / 220 kV / 132 kV AIS & GIS substations and EHV transmission line projects.
- Analyze tender documents, specifications, drawings, and BOQs; perform quantity take‑offs; prepare feasibility studies and pre‑bid/post‑bid cost comparisons.
- Technical & Commercial Evaluation
- Review technical specifications and identify cost‑impacting requirements.
- Evaluate vendor make lists, technical offers, and alternative solutions for optimization; ensure compliance with applicable standards and client requirements.
- Vendor & Commercial Coordination
- Obtain and evaluate quotations from vendors and subcontractors; conduct rate analysis for materials, labour, equipment, and logistics.
- Prepare cost summaries, price break‑ups, and bid pricing sheets; support commercial clarifications, negotiations, and bid finalization.
- Risk Management & Cost Control
- Identify risks, exclusions, assumptions, and constraints during tendering; include contingencies and escalation provisions in estimates.
- Support management with sensitivity analysis and margin assessments.
- Documentation & Reporting
- Prepare and maintain design records, technical reports, cost estimate and tender documentation, clarifications, deviations, and bid submission documents.
- Maintain version control, traceability, and a cost database for completed and ongoing projects; support post‑award technical handover to execution teams.
- Project & Site Support
- Provide technical support during construction, testing, and commissioning as required.
- Assist in design planning, resource allocation, and scheduling of engineering activities.
Required Qualifications
- Bachelor’s degree in Electrical Engineering (Power Systems / High Voltage preferred).
- Professional certifications (Chartered Engineer, MIET, IEEE) are desirable.
- Minimum 5+ years of experience in HV/EHV substation primary design up to 400 kV.
- Proven experience in utilities, EPC contractors, or power transmission design consultancies.
Skills & Competencies
- Proficiency in AutoCAD, MicroStation, and related design tools.
- Strong analytical, calculation, and problem‑solving capabilities.
- Good communication skills with the ability to work in multidisciplinary teams.
- High attention to detail and commitment to quality and deadlines.
Preferred Attributes
- Exposure to BIM workflows and digital engineering practices.
- Knowledge of transmission line engineering interfaces.
- Leadership mindset with the ability to guide and mentor junior engineers.
