Purpose/Objective

Lead end-to-end design engineering for Battery Energy Storage System (BESS) projects from concept to commissioning.

Own system architecture, detailed engineering, technical governance, and design assurance across batteries, power conversion systems (PCS), EMS/SCADA, balance-of-plant (BoP), and grid interconnection.

Drive compliance, optimization, safety, and cost-performance outcomes, enabling bankable designs and successful delivery of utility-scale and C&I; BESS projects.

Key Responsibilities of Role

1.

System Architecture & Front-End Engineering Design (FEED) - Define project-specific BESS architecture (AC/DC topologies, modularity, containerization, microgrid vs grid-tied).

- Prepare FEED packages: SLDs, DC strings/blocks, PCS sizing, transformer/blade specs, auxiliary systems, and thermal management.
- Conduct application-specific sizing and simulations (peak shaving, frequency regulation, energy shifting, black start, islanding, spinning reserve).
- Detailed Engineering & Design Governance - Deliver IFC (Issued for Construction) drawings and documents: SLDs, GA layouts, cable schedules, earthing layouts, protection coordination, equipment datasheets.
- Lead design reviews, value engineering, and change control (RFI/RFQ management).
- Ensure BESS integration with EMS/SCADA, cybersecurity requirements, metering, protection settings, and grid codes.
- Standards, Codes & Compliance - Ensure compliance with relevant standards: IEC/IEEE (e.

g.

, IEC 62933 series, IEC 62443 for cybersecurity, IEEE 1547), fire codes (NFPA 855), UL listings (UL 9540/9540A),



and local electrical rules (CEA/CEA Grid Code), DISCOM requirements.

- Own HAZOP, FMEA, and design risk assessments; implement design mitigations and ALARP principles.
- Champion functional safety, electrical safety, and battery safety (thermal runaway, gas management, fire suppression).
- OEM/Vendor Technical Management - Evaluate and approve OEM technologies (Li-ion chemistries—LFP/NMC, flow batteries, hybrid storage; PCS—central/string; transformers; switchgear; HVAC; fire suppression).
- Technical due diligence on OEM datasheets, certifications, factory audits, FAT protocols, and warranties.
- Lead techno-commercial comparisons (LCOE/LCOS models, lifecycle degradation, round-trip efficiency, availability, OPEX).
- Grid Interconnection & Studies - Coordinate grid studies (load flow, short circuit, harmonic analysis, protection coordination, agile stability).
- Define protection philosophy (relay settings, islanding, anti-backfeed), metering, and synchronization schemes.
- Interface with utilities, SLDCs, DISCOMs, and regulatory bodies for approvals.
- Controls, EMS & Cybersecurity - Define EMS/PCS control strategies (SoC management, dispatch profiles, droop control, AGC/AR,



frequency/watt-volt control).
- Oversee SCADA architecture, communication protocols (Modbus, IEC 61850), network segregation, and cyber hardening.
- Approve control narratives and FAT/SAT test cases; ensure performance guarantees are testable.
- Project Delivery Support - Support procurement with technical specs and bid evaluations; manage technical deviations.
- Support construction with design clarifications, site queries, as-built documents, and redline mark-ups.
- Participate in FAT/SAT/commissioning and performance testing; close non-conformities.
- Team Leadership & Stakeholder Management - Manage a design engineering team (electrical, controls, civil, HVAC/fire), set priorities, and mentor talent.
- Collaborate with EPC, OEMs, project management, HSE, quality, and finance for integrated delivery.
- Present technical solutions to clients, lenders, and internal leadership.
