Sargent & Lundy Congratulates Hajr on Winning Top Plant Recognition

Qurayyah IPP combined-cycle project earns numerous accolades

September 15, 2015 – Sargent & Lundy extended its congratulations to Hajr Electricity Production Co. on winning Top Gas-Fired Plant recognition from Power magazine for the Qurayyah IPP Combined-Cycle Power Plant. At 4000 MW, Qurayyah IPP is one of the largest combined-cycle plants in the world and the most efficient power plant in Saudi Arabia. Sargent & Lundy served as the engineer on this highly successful project.

The facility has six 2-on-1 combined-cycle blocks with 12 turbine generating units, 12 heat recovery steam generators (HRSGs), 6 steam turbine generators, and 6 seawater cooled condensers. The plant is designed to endure harsh site conditions from heavy sand storms to temperatures that can exceed 50ºC (120ºF).

Measures to offset the extreme heat include a specially designed inlet chilling system. The system is designed to lower the turbine inlet air temperature to 15 ºC (59 ºF) over a wide range of ambient conditions to increase the plant power output.

The project award was announced in the September 2015 issue of Power. A profile of the project is featured on the Power website.
