900 MW Bin Qasim Power Station 3 Project

Also known as: 900 MW Karachi BQPS III Project, 900 MW Bin Qasim Combined Cycle Power Plant Project
Ongoing

Background

K-Electric Co Ltd planned to develop 900 MW Karachi Bin Qasim Power Station 3 Project in Karachi, Pakistan. Consortium of Siemens AG and Harbin Electric International Co Ltd was the construction contractor. China Energy Engineering Group Tianjin Electric Power Construction Co Ltd (Energy China TEPC) was the construction contractor. The project covered the construction of two SGT5-4000F gas turbines, two 450MW combined-cycle power generation units, heat recovery steam generators, gas-insulated switchgear, gas compressor station, steam turbine, bypass stacks, transformers cooling water system, a centralized control room, and upgrades of associated transmission infrastructure. The two SGT5-4000F gas turbines (The SGT5-4000F gas turbine is a heavy-duty gas turbine with a 329MW power output and 50Hz frequency which weighs 318000 kg and has a heat rate of 8780 kJ/kWh) would be installed in the two 450MW combined-cycle power generation units seven and eight. The new units will be situated within the premises of BQPS-I to replace the existing natural gas and HFO-based power generation units three and four. Unit seven will initially operate in open-cycle and, later, in combined-cycle, following decommissioning of BQPS-I unit four. Unit three will be decommissioned to install unit eight, which will also be a combined-cycle unit. The turbine offers low power generation cost and has a service-friendly design, providing improved performance. It also has a dual-fuel capability and its fuel system can switch between fuel gas and fuel oil and vice-versa. The gas turbine house will feature a ventilation system that will also act as emergency ventilation. The SGT5-4000F features an advanced annular combustion system and hydraulic clearance optimization (HCO) active clearance control. It operates at a speed of 3,000 revolutions per minute (rpm) and includes a 15-stage axial-flow compressor. The plant in this project was designed for a life of 30 years. The project would address the supply-demand gap, which was created by the decommissioning of two BQPS-I existing heavy furnace oil (HFO) units. It would also reduce the energy generation cost and improve efficiency. This project would promote the Belt& Road Initiative cooperation between Pakistan and China.
