BESS Analyst (Design & Estimations)/ BESS Manager – Design, Engineering & Cost Estimation

Company Description

Battery Energy Storage System (BESS) Manager

design, engineering, techno-commercial evaluation, and cost estimation

1 MWh to 100 MWh

Key Roles & Responsibilities

• Lead technical and financial feasibility assessments for BESS deployments integrated with solar, wind, or hybrid renewable energy projects.
• Drive battery sizing optimization based on project needs—such as peak shifting, load smoothing, frequency regulation, or energy arbitrage.
• Prepare and validate cost estimates including CAPEX, OPEX, EPC costs, commissioning, and lifecycle expenses.
• Develop Levelized Cost of Storage (LCOS) models for multiple BESS architectures (e.g., centralized vs distributed).
• Conduct system design using modelling tools, ensuring compliance with performance requirements and cost effectiveness.
• Collaborate with internal teams (engineering, BD, EPC, O&M) and external stakeholders (vendors, consultants) to align technical design and commercial goals.
• Evaluate and benchmark vendor offers for battery packs, PCS, EMS, and BoP equipment; provide Total Cost of Ownership (TCO) analysis.
• Stay updated with policy, regulatory, and market developments impacting energy storage deployment in India (e.g., IEGC, CEA guidelines, SECI tenders).
• Support business development and proposal teams with techno-commercial inputs, tender documentation, and client presentations.
• Contribute to internal knowledge development, standardization of BESS cost libraries, and design templates.
  

Qualifications

Qualifications & Requirements
