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

Job Description:

We are seeking a highly motivated and technically proficient Battery Energy Storage System (BESS) Manager with 510 years of hands-on experience in the design engineering techno-commercial evaluation and cost estimation of BESS solutions in India. The ideal candidate will bring a deep understanding of various BESS technologies their application in hybrid renewable projects (Solar Wind or both) and strong cost modelling capabilities for systems ranging from 1 MWh to 100 MWh.

This role is critical to evaluating BESS deployment for utility-scale projects optimizing technical configurations and supporting investment-grade proposals.

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 needssuch 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 :
