We are looking for an experienced Solar PV + Battery Energy Storage System (BESS) Design Engineer to support the engineering and design of utility-scale solar power plants, standalone BESS projects, and integrated solar-plus-storage projects.

1. Solar PV Plant Design and Engineering

· Develop conceptual, preliminary, and detailed engineering designs for utility-scale ground-mounted solar PV projects.

· Prepare and review DC and AC system designs, including module string configurations, inverter sizing, DC/AC ratio, and electrical equipment selection.

· Prepare Single Line Diagrams (SLDs), electrical layouts, cable sizing and routing, earthing, lightning protection, and illumination designs.

· Undertake transformer sizing, inverter transformer selection, HT/LT switchgear sizing, and auxiliary power system design.

· Prepare and review technical specifications, equipment datasheets, BOQs, and engineering calculations.

· Conduct solar energy yield assessments and performance simulations using PVsyst or equivalent software.

· Review module, inverter, transformer, switchgear, and other electrical equipment technical submissions.

· Support the design of plant evacuation systems, pooling substations, and grid connectivity arrangements.

2. Battery Energy Storage System (BESS) Design

· Develop electrical designs for standalone BESS and integrated Solar PV + BESS projects.

· Perform preliminary BESS capacity sizing based on power rating (MW), energy capacity (MWh), discharge duration, operating profile, and project requirements.

· Evaluate battery technologies, battery configuration, PCS/inverter selection, and energy management requirements.

· Design and review BESS electrical architecture, including battery containers, Power Conversion Systems (PCS), transformers, MV switchgear, and auxiliary systems.

· Coordinate the integration of Battery Management Systems (BMS), Energy Management Systems (EMS), and SCADA.

· Evaluate round-trip efficiency, auxiliary consumption, usable energy, depth of discharge, degradation, and augmentation requirements.

· Review BESS supplier proposals, technical specifications, performance guarantees, and system integration requirements.

· Coordinate with OEMs and technology providers on electrical integration, control philosophy, protection, and grid compliance.

· Support the evaluation of battery safety systems, thermal management, fire detection, and fire suppression requirements in coordination with relevant specialists.

3. Grid Integration

· Support power flow, load flow, short-circuit, protection coordination, and grid compliance studies.

· Coordinate grid synchronisation, reactive power management, power factor control, and voltage and frequency response requirements.

· Evaluate system performance against applicable grid codes, utility requirements, and tender specifications.

· Support the technical evaluation of hybrid renewable energy projects involving solar, wind, and BESS, wherever applicable.

4. Technical Skills

· Demonstrated experience in utility-scale solar PV plant design and preferred exposure to high-voltage systems up to 230KV/400KV

· Practical knowledge of BESS sizing, electrical integration, PCS, BMS, EMS, and grid interface requirements.

· Proficiency in AutoCAD and MS Office.

· Working knowledge of PVsyst and electrical design and analysis tools such as ETAP, PowerFactory, or equivalent software.

· Familiarity with Indian Electricity Rules, applicable CEA regulations, relevant IS/IEC standards, grid codes, and utility requirements.

· Ability to interpret technical specifications, SLDs, layouts, equipment datasheets, and tender documents.

· Strong analytical, problem-solving, documentation, and technical coordination skills.

5. Preferred Experience

· Experience in utility-scale solar projects, preferably > 200 MW.

· Experience in standalone BESS or integrated Solar PV + BESS projects for a capacity > 50MWH

· Exposure to grid-scale BESS, renewable energy integration, and power evacuation systems.

· Experience with EPC contractors, renewable energy developers, engineering consultants, or owner’s engineering organisations.

· Experience in tender engineering, technical bid evaluation, and coordination with domestic and international OEMs.
