Job Description

Role Overview

The Electrical Senior Design Engineer Solar BESS will serve as the technical authority for the electrical engineering and system integration of utility-scale or CI solar PV and Battery Energy Storage Systems. This role focuses on the complex electrical architecture of hybrid plantsspanning from DC generation and electrochemical storage up to high-voltage grid substations. You will be responsible for ensuring that all electrical designs are optimized for efficiency, safety, and absolute compliance with utility grid codes.

Key Responsibilities

1. Advanced Electrical Engineering System Architecture
- Electrical Architecture: Design complex AC-coupled and DC-coupled utility-scale Solar-plus-BESS plant topologies.
- Core Calculations: Perform and validate critical electrical calculations including AC/DC cable sizing, ampacity, voltage drop, transformer sizing, earthing/grounding grids, and lightning protection.
- Power System Analysis: Conduct or supervise system studies using software like load flow analysis, short-circuit studies, relay coordination,



and arc flash analysis.
- Engineering Deliverables: Author and review comprehensive electrical engineering packages: Single Line Diagrams (SLD), Three Line Diagrams (3LD), schematic drawings for control protection, and cable trench/routing layouts.

2. Equipment Selection Technical Procurement
- Specification Authoring: Define technical specifications and datasheets for key electrical equipment: Power Conversion Systems (PCS), Central/String Inverters, MV/HV Transformers, Switchgears, Ring Main Units (RMU), and Battery Enclosures.
- Vendor Qualification: Lead the technical evaluation of bids from OEMs and EPC contractors. Review and approve vendor drawings (e.g., GA drawings, control schematics) to ensure alignment with project requirements.
- BOM Management: Ownership of the electrical Bill of Materials (BOM) and Bill of Quantities (BOQ) from the conceptual phase to Valuable-for-Construction
