  AS part of my role, I am tasked with overseeing the Electrical Systems aspects of the Engineering, Procurement, and Construction (EPC) process for a 350 MW LNG Combined Cycle Power Plant project. This involves a diverse range of responsibilities aimed at ensuring the effective operation and integration of electrical components within the plant. My duties include designing the Electrical Balance of Plant (EBOP), encompassing High Voltage (HV), Medium Voltage (MV), Low Voltage (LV), Direct Current (DC), and Uninterruptible Power Supply (UPS) Systems. I conduct power system simulations utilizing ETAP software to optimize load flow and fault studies, ensuring the system's stability and reliability. Additionally, I design supplementary systems tailored for specific equipment such as Siemens SGT5 4000F Gas Turbine, Siemens SST5 3000 Steam Turbine, and HBG HRSG. I develop a Siemens SPPA-T3000 based Distributed Control System (DCS) for effective monitoring and control of the plant's operations. Safety is a priority, and I design robust earthing and lightning protection systems. I meticulously plan and design cabling systems for HV, LV, and MV systems, as well as Black Start Generator Systems, fire detection systems, lighting, and small power systems. In addition, I am responsible for creating comprehensive reports, deliverables lists, and procurement lists, and I manage the procurement process, including supplier evaluation, selection, and supply chain management. I review supplier drawings and designs to ensure compliance with project requirements. Finally, I oversee the commissioning, energizing, performance testing, and reliability test runs to ensure the functionality and efficiency of the electrical systems under real-world conditions.

This encompassed overseeing the day-to-day maintenance and operation of various electrical systems, including a 220kV HV system, 6kV MV system, LV system, and DC system. Additionally, I managed the maintenance and operation of sophisticated control systems such as the GE Mark VI control system, ABB 800xA control system, Power Generation Information Manager (PGIM) server system, GE Fanuc PLC, and Siemens S7 PLC. In addition to my duties at the combined cycle power plant, I also handled the operation and maintenance of Minihydro power plants and Wind power plants. Furthermore, I served as a Lead Auditor for ISO 45001, focusing on Occupational Health and Safety, and ISO 50001, which pertains to Energy Management Systems. This role involved conducting audits, ensuring compliance with standards, and driving improvements in health, safety, and energy management practices within the organization. Show less
