BESS Specialist

• Lead the technical and commercial structuring of BESS components within utility solar tenders — defining system capacity, duration, cycling assumptions, and grid services capability.
• Develop and maintain BESS financial models — including dispatch revenue, grid services income, degradation assumptions, capex/opex buildups, and project IRR contribution.
• Advise on optimal BESS system architecture for each project based on site requirements, grid conditions, and offtake terms.
• Review and validate BESS technical specifications provided by equipment suppliers and EPC contractors.
• Lead BESS component preparation for all LSS6 and future tender submissions requiring storage integration.
• Ensure BESS elements of tender submissions are technically accurate, commercially competitive, and compliant with programme requirements.
• Support the EPCC team in evaluating BESS subcontractors and equipment suppliers for tender nominations.
• Track TNB, EC, and SEDA announcements on grid services, ancillary markets, and storage-related policy developments.
• Assess revenue opportunities from frequency regulation, peak shaving, and other grid services for applicable projects.
• Brief all four pillars on relevant storage policy developments that affect project economics or tender requirements.
• Support financial close preparation for projects with BESS components — preparing lender-ready technical descriptions, operating assumptions, and risk summaries.
• Engage with BESS equipment suppliers, independent engineers, and technology consultants on project-specific requirements.

Requirements

• 3–5 years in battery energy storage, grid-scale energy, or utility-scale solar with storage integration.
• Hands-on experience structuring BESS components for project finance or competitive tenders.
• Financial modelling proficiency — storage dispatch economics, degradation, grid services revenue.
• Familiarity with Malaysian energy policy (LSS, EC guidelines, TNB grid requirements) is a strong advantage.
• Deep understanding of BESS system architecture — lithium-ion chemistry, inverter configurations, DC/AC coupling, BMS requirements.
• Able to review and challenge technical specifications from equipment suppliers and EPC contractors.
• Proficient in Excel financial modelling with storage-specific variables.
