Background

Aluminium Bahrain (Alba) is planning the expansion of its Power Station 5 (PS5) located in the Askar Industrial Area, in Bahrain. PS5 Block 4 project is the addition of a fourth Block of similar 1:1:1 configuration with J-class gas turbine technology and with a minimum nominal ISO rating of 680.9-MW and includes a tie into the existing 220 kV Substation. The efficiency of this combined cycle power plant is much higher than the combined cycle power plants of PS3 and PS4. On completion of the PS5 Block 4 Expansion project, the nameplate capacity of PS5 will increase from 1,800 MW to 2,481 MW.
