Saudi Aramco has awarded Germany’s Siemens a deal worth almost $1bn to supply components for its planned gasification project that will be constructed next to the $7bn Jizan refinery in south west Saudi Arabia.

The deal, worth $966.8m, will see Siemens provide the components for a combined-cycle power plant with a capacity of 4,000MW. This will make it the largest gasification power plant in the world.

The scope of supply will include 10 gas turbines that are designed to run on synthesis gas and diesel fuel, 15 generators and 10 heat recovery steam generators. Six of the 10 gas turbines will be manufactured in the kingdom by Siemens.

Initially the Jizan scheme was to supply the Jizan refinery and other potential industries in the Jizan Economic City, but the new capacity is planned to supply the city of Jizan with additional power capacity.
