Design Lead (Electrical AC) - Solar

Role Summary

The Design Lead (Electrical AC) will oversee and execute engineering tasks such as creating AC single line diagrams (SLD), building and earthing layouts, cable sizing calculations, transformer sizing, and selection of LT/HT breakers specifically for Solar PV power plants. They will also guide modelers in developing BIM 3D models for these projects. This role demands coordination across multiple disciplines including Civil/Structural, Instrumentation, and MEP to ensure thorough inter-departmental checks. The Design Lead will support the full engineering lifecycle from pre-bid stage through commissioning and warranty phases, extending assistance to the site team throughout.

The position includes leading a team of Design Engineers and Draughtspersons, with a strong focus on delivering high-quality engineering outputs on time and within budget.

Key Responsibilities

• Deliver engineering drawings and documents promptly, ensuring alignment with project timelines.
• Review designs and sizing calculations performed by team members and attain client approvals.
• Evaluate vendor submissions related to engineering and ensure compliance.
• Manage multiple tasks and meet deadlines efficiently.
• Estimate and plan resource man-hours for engineering activities.
• Review Bills of Quantities (BOQ) and provide technical clarifications to the contracts team.
• Coordinate inter-disciplinary checks with various teams.
• Provide necessary support and clarifications to the site execution teams.
• Conduct pre-award technical evaluation of vendors and liaise with supply chain management.
• Inspect equipment from approved vendors post-validation.
• Clarify design and client requirement-related issues to site teams.
• Gather project-specific inputs such as plot details and feeder arrangements from clients and engineering managers.
• Coordinate with operations for design specification approvals.
• Obtain general arrangement drawings from vendors and review equipment, cable routing, cable tray, earthing, lighting, and lightning protection layouts.
• Assist Electrical DC, Civil and Structural teams in reviewing vendor designs.
• Submit resource requirements for design and drawing reviews.

Technical Skills and Knowledge

• Familiarity with Dialux and proficiency in MS Office; knowledge of ETAP is preferred.
• Comprehensive understanding of equipment layouts and electrical engineering calculations linked to Solar PV power plants.
• Expertise in engineering tasks including SLD preparation, layout design, earthing, cable routing, lighting, lightning protection, and cable tray routing.
• Ability to perform calculation and design validation for Busbar, UPS, Battery systems, LT Transformer, Earthing Conductors, and short circuit forces.
• Knowledgeable about national and international electrical codes and standards.
• Capable of interpreting contractual technical requirements and guiding project teams accordingly.
• Broad comprehension of interdisciplinary design aspects involving Electrical, Civil & Structural, Mechanical, and Instrumentation disciplines.

Qualifications and Experience

• Bachelor’s degree in Electrical or Electrical & Electronics Engineering (B.E./B.Tech).
• A minimum of 10 years’ experience with a strong focus on design aspects of Solar PV Power Plants or Power Distribution projects.
