PS5 Block 4 Expansion Project

Power Station 5 (PS5) Block 4 is a Combined Cycle Power Plant that is an expansion of the existing PS5.

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 minimum nominal ISO rating of a 680.9 MW and includes tie into the existing 220kV 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 PS5 Block 4 Expansion Project, the nameplate capacity of PS5 will increase from 1,800 MW to 2,481 MW.

Mitsubishi Power & SEPCOIII consortium will be responsible to design, engineer, procure, construct and commission Block 4. PS5 Block 4 commercial operations are expected to begin in Q4 2024.
