Responsibilities

The following duties are typical of the position but are not all encompassing. Responsibilities include those required to deliver quality service on schedule and within budget in a team environment.

• Lead end-to-end HV (high voltage) substation design (typically 69 kV500 kV):
• Primary: bus configurations (ring bus, breaker-and-a-half, double bus), equipment layouts, general arrangements, sections/elevations, equipment sizing and ratings (including BIL), conductor/busbar selection, lightning protection, insulation coordination.
• Secondary/Protection & Control: SLDs/three-lines, protection one-lines, AC/DC schematics, wiring diagrams, panel layouts, cable schedules, I/O lists, RTU/SCADA integration, points lists, relay logic/settings.
• Grounding/Earthing: ground grid design and studies (touch/step voltages), grounding plans and details.
• Auxiliary systems: station service AC, DC systems and battery sizing, charger selection, UPS as required.
• Prepare technical specifications/datasheets and perform vendor bid evaluations for transformers, breakers, disconnects, instrument transformers (CTs/PTs/CCVTs), surge arresters, control panels, cables, raceways, and ancillary equipment.
• Perform and/or review power system studies: short-circuit, protection coordination, arc flash (per NFPA 70E/IEEE 1584), load flow as applicable; contribute to insulation coordination and ferroresonance/temporary overvoltage assessments as needed.
• Ensure compliance with NEC (NFPA 70), NEMA standards, and NERC reliability and cyber requirements (e.g., PRC/CIP awareness for protection and SCADA).
• Coordinate multi-discipline inputs (civil/structural, telecom, automation) and interface with utilities, ISO/RTOs, and client engineering teams.
• Lead QA/QC reviews, check deliverables from junior engineers/designers, and enforce internal standards and best practices.
• Provide construction and commissioning support: respond to RFIs, review submittals, support FAT/SAT, and prepare as-built documentation.
• Support proposals/estimating, work plans, schedules, level-of-effort, and client presentations; contribute to standardization and process improvements.
• Mentor junior engineers and CAD/BIM designers; help build technical depth in the Mumbai team.
