Responsibilities
- Study the electrical primary technical specifications in bidding documents (Bases de Licitación) of Comisión Federal de Electricidad (CFE), and sort out mandatory clauses, special conditions (high altitude, salt spray, seismic zone design), and technical scoring criteria.
- Identify potential technical risks (e.g., insufficient insulation coordination margin, excessive short-circuit current) and submit Technical Risk Early Warning Reports to the bidding leader.
- Develop electrical main wiring schemes (single bus, double bus, bridge connection, etc.) for substations/boosting stations, and complete general layout and structure/bracket selection.
- Calculate short-circuit current levels and determine rated parameters of main equipment (transformer capacity/ratio/impedance, breaker interrupting capacity, isolator rated current, etc.).
- Prepare technical specifications (English/Spanish) for primary equipment: transformers, GIS/AIS switchgear, reactive power compensation, arresters, busbars, insulators, etc.




- Cooperate with procurement teams to review technical deviation forms from suppliers (Siemens, ABB, Hitachi Energy, Prolec GE, etc.) and verify compliance with CFE LAPEM certification.
- Accurately calculate Bill of Quantities (BOQ) for electrical primary equipment, cables, grounding, lighting, and lightning protection systems.
- Assist cost engineers in cost estimation and quotation analysis for electrical primary systems.
- Coordinate with CFE-certified local design institutes or Chinese partners to conduct internal reviews of preliminary design drawings for bidding.
- Prepare formal written responses to CFE technical clarifications (Aclaraciones).
- Provide structure/bracket loads and foundation dimensions to the civil engineering discipline.
- Provide CT/PT configuration and breaker control voltage requirements to the electrical secondary discipline.
- Define bay layout and conductor tension data for transmission line discipline.
- Establish
