PS5 Block 4 Expansion Project

Alba's Power Station 5 (PS5) Block 4 is a new 680.9-megawatt (MW) combined-cycle power plant that expands the existing PS5 facility.

This state-of-the-art J-class gas turbine addition boasts superior efficiency compared to Power Stations 3 & 4. Scheduled for completion in Q4 2024, Block 4 will boost PS5's total capacity to 2,481 MW, while reducing greenhouse gas emissions by 0.5 tonnes of CO2 per tonne of aluminium produced.

A consortium of Mitsubishi Power and SEPCOIII is responsible for the entire project lifecycle, from design and engineering to construction and commissioning. Alba has achieved in April 2024 the first fire of the state-of-the-art GT for Block 4 Project.
