Short-circuit, voltage drop, earthing, lightning protection calculations,
-
Lighting design using Dialux / Relux.
Schematics & drawings:
-
Single-line diagrams and synoptic diagrams,
-
HV/LV distribution schemes,
-
Cable schedules and lists,
-
Routing plans and layout drawings.
2. Technical Coordination & Interfaces
Coordinate interfaces with:
-
Battery process (coating, assembly, calendaring, etc.),
-
HVAC / utilities (power requirements, control),
-
Safety systems: fire detection (SSI), sprinklers, gas suppression,
-
PLCs, BMS / SCADA systems.
Integrate specific gigafactory constraints:
-
Very high continuous loads,
-
Sensitivity to power continuity,
-
High energy redundancy,
-
Critical environments: dry rooms.
3. Construction Support & Execution Follow-up
-
Reviewing execution studies: calculation notes, schematics, technical documents.
-
Ensuring compliance with standards: NF C15-100, IEC, EN.
-
Handling RFI, technical discrepancies, and participation in design approvals.
-
On-site technical support:
-
Installation checks,
-
FAT/SAT for transformers, switchboards, UPS, etc.,
-
Testing and commissioning.
-
4. Documentation & Project Management
-
Writing: technical specifications (CCTP), calculation notes, design documents (APS/APD/EXE), datasheets.
-
Contributing to tenders and supplier selection.
-
Monitoring design schedules and reporting to the Electrical Lead.
-
Participation in multidisciplinary meetings and BIM reviews (Revit MEP).
Technical Skills Required
-
Medium/Low Voltage: transformers, MV switchgear, main switchboards.
-
UPS, generators, redundancy.
