BESS Electrical Lead

Roles & Responsibilities

• The Electrical Lead is responsible for leading the electrical design, engineering, and grid?interface activities for utility?scale and C&I battery energy storage projects. The role ensures that all BESS solutions comply with applicable grid codes, safety standards, and customer requirements, from concept through commissioning and handover.

Key Responsibilities

• Lead end?to?end electrical design of BESS plants, including single?line diagrams, cable sizing, grounding/earthing, protection schemes, and equipment specifications (transformers, switchgear, RMUs, UPS, etc.).
• Define and validate grid?connection requirements with utilities (voltage levels, fault levels, protection interfaces, metering, power quality, and grid?code compliance such as frequency/voltage support, reactive power, and ramp?rate limits).
• Review and approve integration of PCS/inverters, BMS, EMS, and SCADA from an electrical and protection perspective.
• Perform or supervise load?flow, short?circuit, and protection coordination studies, and support harmonic and power?quality studies with specialist consultants where required.
• Ensure designs comply with relevant international and local standards (e.g., IEC/IEEE for switchgear, transformers, protection, and storage systems; applicable grid codes; electrical safety regulations).
• Own and maintain internal electrical design standards, templates, and checklists for BESS and grid?connected systems.
• Define protection philosophies and interlocking schemes for safe energization, isolation, and maintenance of BESS and grid?connected equipment.
• Drive design reviews (HIRA/HAZID/HAZOP where relevant) focusing on electrical safety, arc?flash risk, and functional safety for critical controls.
• Technical Leadership & Coordination
• Act as electrical technical authority for BESS projects, providing guidance to internal teams and external partners (EPCs, OEMs, consultants).
• Plan and coordinate electrical engineering deliverables, ensuring scope, quality, schedule, and cost targets are met.
• Review vendor/OEM documentation for transformers, switchgear, protection relays, converters, cabling systems, and auxiliary power systems; provide technical clarifications and approvals.
• Support construction, FAT/SAT, and commissioning teams with procedures, test plans, and resolving site technical issues (protection settings, trips, synchronization, etc.).
• Lead technical discussions with customers, utilities, and regulatory bodies on grid?connection studies, interconnection requirements, protection schemes, and compliance evidence.
• Translate customer requirements, tender specifications, and utility interconnection agreements into clear electrical design inputs and deliverables.
• Provide technical support to sales and bid teams, including concept designs, BOQs, loss calculations, and clarifications during tender stages.
