Al Dur II IWPP Combined Cycle (1,500 MW): Comprehensive engineering for Bahrain’s largest power plant
Bahrain
The Al Dur II IWPP Combined Cycle is a major energy project located in the Southern Governorate of the Kingdom of Bahrain, awarded by the Electricity and Water Authority (EWA) to ACWA POWER. This combined cycle power plant, with a total capacity of 1,500 MW and equipped with SIEMENS technology, features two multi-shaft blocks and can operate in both simple and combined cycle modes. IDOM provided complete engineering services, from basic design to detailed engineering, ensuring the plant’s efficiency and sustainability. The Al Dur II IWPP Combined Cycle also includes seawater cooling towers and an expander to maximize energy use from natural gas.
Awarded by EWA (Electricity and Water Authority) to ACWA POWER, the Al Dur II IWPP project consists of a Combined Cycle Power Plant and a Desalination Plant in the Southern Government of the Kingdom of Bahrain. It occupies an area of approximately 192,500 m² immediately south of the existing Al Dur I IWPP plant, on the Arabian Gulf coastal strip.
The combined cycle plant has a 2-block configuration, each in 2x2x1 multi-axis mode, with a total generation capacity of 1,500 MWe. Both gas and steam turbines are supplied by SIEMENS, with gas turbines (SGT5-4000F), single fuel using natural gas. It can operate in both Single Cycle mode and Combined Cycle mode, and the main cooling is carried out by cooling towers using seawater.
The plant has a turboexpander that takes advantage of the high pressure of the natural gas available in the supply network to generate electricity while reducing the gas pressure to the requirements established by SIEMENS for their turbines.
ACWA POWER awarded SEPCOIII the construction project of the Power Plant under an EPC arrangement, for which IDOM has developed the complete engineering (basic and detailed).
