German engineering group Siemens has won a $400m contract to supply five large gas turbines to be installed at the Fadhili combined heat and power (CHP) plant.

The five F-class gas turbines will be manufactured in the kingdom installed at the CHP plant, which will supply Saudi Electricity Company’s (SEC) under-construction Fadhili gas extraction plant.

The plant will have an electrical generating capacity of about 1,500MW and will supply about 400MW of electricity and process steam to the gas plant which is located 100km northwest of Dammam in the Eastern Province of the Kingdom.

The additional 1,100MW will be enough to supply power to 1.1 million Saudi households, Siemens said.

All five turbines will be produced at the Siemens Dammam Energy Hub (SDEH).

The turbines will be purchased by the power plant’s engineering, procurement and construction (EPC) construction contractor, South Korea’s Doosan Heavy Industries & Construction Company.

Siemens and Kahrabe, an affiliate of the CHP plant’s developer Engie Group, signed a long-term service agreement for the gas turbines for the Fadhili CHP plant for a period of 16 years.

The Fadhili gas plant including the CHP project is scheduled to be completed by the end of 2019 and will play a key role in expanding the gas production and supply in Saudi Arabia to meet growing domestic energy demand.

Fadhili will produce more than 5 billion cubic feet a day (cf/d) of non-associated gas. Saudi Aramco is investing a total of around SR50bn ($13.3bn) in the Fadhili gas extraction plant.
