The power plant is based on Alstom’s proven and mature combined-cycle technology, which has over three million operating hours. This has the benefit of not only providing high plant efficiency (>50 %), but also exceptional operational availability and flexibility. The Sohar CCPP exclusively powers a green field aluminium smelter operated by the Sohar Aluminium Company LLC and most importantly is the largest power generation plant in the Sultanate.
