The Project
The combined cycle power unit will have a generating capacity of 680.8 MW at 25°C and an efficiency of 54.6%. The main equipment to be provided include one M701JAC Mitsubishi gas turbine, one Hitachi steam turbine, one SPX-Air Cooled Condenser, one XIZI HRSG in addition to balance of plant and other electrical/control equipment.
Technology
The M701JAC is an advanced high temperature, high efficiency, low NOx, large capacity gas turbine.
Foreseen Benefits Upon Commissioning
Capacity
Upon completion, this Project will increase the nameplate capacity of Power Station 5 Complex from 1.8 GW to 2.4 GW
Efficiency
The Power stations’ efficiency will increase from 48.70% to 50.99% and from 50.02% to 52.25% during summer and winter respectively with the addition of Power Station 5 Block 4.
Greenhouse Gas (GHG) Emissions
Having a higher efficiency, Block 4 will enable Alba to reduce its Greenhouse Gas Emissions in line with the Kingdom’s Objectives of Net Zero Emissions by 2060 and the Company’s ESG Roadmap.
The Project Management
Alba core team spearheads this Project in collaboration with ESBI International, Ireland.
The Consortium consists of SEPCOIII, Tiejun International DMCC and Mitsubishi Power Limited. Local subcontractors have also been engaged during the execution of works.
