BESS Design Engineer

INTEC Energy Solutions delivers best-in-class services in Engineering, Procurement, Construction (EPC), Battery Energy Storage Systems (BESS), Development, Consultancy, and Operation & Maintenance, along with New Energy Solutions. With a globally experienced team, INTEC has managed over 190 projects and achieved an impressive installed and secured capacity of 3.9 GWp. Headquartered in the United Kingdom, INTEC also operates offices in Germany, Türkiye, Australia, New Zealand, Azerbaijan, Romania, and Mauritius, with plans for further expansion.

Summary : We are seeking a technically proficient BESS Design Engineer to support the end-to-end EPC delivery of utility-scale Battery Energy Storage System (BESS) projects. This role involves not only system design and performance optimization, but also collaboration across engineering, procurement, and construction teams to ensure designs are practical, cost-effective, and aligned with execution timelines. You will work on everything from feasibility through to construction drawings and commissioning support—bridging the gap between design intent and real-world project delivery.

Key Responsibilities :

• Develop BESS system designs optimized for EPC constructability , including layout drawings, integration schematics, and BoP configurations.
• Specify battery technologies, inverters, protection systems, and associated power electronics for containerized or modular BESS installations.
• Perform load flow, short-circuit, and system performance simulations to validate BESS system architecture.
• Collaborate with electrical, civil, and SCADA teams to integrate designs into overall plant infrastructure and control frameworks.
• Work with procurement and construction teams to ensure technical packages align with vendor offerings and site execution plans.
• Stay current with UK and international codes, such as G99, BS EN 61960, and IEC standards applicable to BESS and electrical systems.
• Participate in technical reviews with DNOs, suppliers, and subcontractors to validate interface points and design assumptions.
• Conduct design risk assessments and value engineering activities to enhance system reliability and reduce lifecycle costs.
• Support project managers in EPC tendering, cost estimates, and design documentation for client and permit submissions.
• Provide engineering support during construction and commissioning phases to resolve design issues or adapt to site conditions.
