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.
