Deskripsi pekerjaan
Feasibility and system design
● Lead feasibility studies for BESS and microgrid opportunities: load profiling, tariff and demand-charge analysis, diesel displacement, and techno-economic modelling (LCOE / LCOS, IRR, payback).
● Size BESS (power and energy), PV and genset capacity for hybrid and off-grid systems, including degradation, augmentation strategy and end-of-life planning.
● Define system architecture: AC- vs DC-coupled, PCS selection, grid-following vs grid-forming operation, black-start and islanding capability.
● Specify EMS / microgrid controller functions: peak shaving, load shifting, PV smoothing and ramp-rate control, spinning-reserve replacement, frequency and voltage support, and genset dispatch optimization.
Grid integration and compliance
● Lead grid-connection and interconnection studies (load flow, short circuit, protection coordination, dynamic/stability studies) and ensure compliance with PLN grid code and SPLN requirements.
● Ensure designs comply with applicable standards for battery safety and fire protection (e.g. IEC 62933, IEC 62619, UL 9540 / 9540A, NFPA 855) and Indonesian K3 / electrical safety regulations.
Procurement and vendor management
● Prepare technical specifications and RFQs for battery systems, PCS, EMS/controllers, transformers and switchgear.
● Run technical bid evaluations and vendor due diligence (cell supplier, factory audits, warranty and performance guarantee terms, LTSA/O&M scope).
● Negotiate and review technical schedules of supply and EPC contracts, including availability, round-trip efficiency and capacity-retention guarantees.
Operations and performance
● Define performance KPIs (availability, Performance Ratio, Energy Absorption, RTE, SoH, diesel saved, curtailment, BESS Utilization) and monitoring/SCADA requirements.
● Analyse operational data to optimise dispatch strategy, track degradation against warranty curves, and support warranty claims.
Business development and team support
● Support BD and proposal teams with technical solutions, budgetary pricing and client presentations for C&I, mining, industrial and island-grid clients.
● Build internal BESS capability: templates, design standards, lessons learned, and mentoring of junior engineers.
Expected deliverables
● Feasibility and sizing reports with techno-economic models for each opportunity.
● Basic and detailed design packages: SLDs, protection philosophy, layouts, control and EMS functional specifications.
● Grid-connection study reports and PLN submission packages.
● Technical specifications, RFQ packages and bid evaluation reports.
● Fire and hazard risk assessments and safety design basis.
● FAT/SAT and commissioning test procedures and reports.
● Performance and degradation reports for operating assets.
● In the first 12 months: an in-house BESS design and procurement standard for the company.
Requirements
● Minimum 3 years of direct, hands-on BESS and microgrid experience, within a total of roughly 6+ years in power systems, renewable energy or electrical engineering.
● Delivered at least two BESS or hybrid microgrid projects from design through commissioning (ideally ≥1 MWh each), with a clear personal role in sizing, design or commissioning.
● Experience with at least one of: solar-plus-storage hybrid, diesel-hybrid / off-grid microgrid, or C&I behind-the-meter BESS.
