Siemens has received an order for five F-class gas turbines for a combined heat and power (CHP) plant in the Kingdom of Saudi Arabia, Diesel & Gas Turbine Worldwide reported.

With a generating capacity of around 1,200-1,500MW, the plant will supply electricity and process steam to a new natural gas extraction plant in Fadhili, which is located around 120km northwest of Dammam, Al Bawaba wrote.

The additional capacity will be sufficient to supply power to 1.1m Saudi households, and the turbines will be produced at the Siemens Dammam Energy Hub (SDEH), the Middle East’s largest gas turbine manufacturing facility.

Siemens’ scope of supply encompasses five SGT6-5000F gas turbines, five SGen6- 1000A generators, the control system SPPA-T3000 as well as assembly and commissioning on site. The long-term service agreement covers maintenance services for the five turbines including Siemens’ advanced Power Diagnostics services, part of the company’s Digital Services for Energy portfolio.

Siemens Power Diagnostics is designed to provide a detailed diagnosis of many actual unit conditions and recommendations for improvements to help minimize unplanned outages and maximize power generation availability.

The new power plant will be largely fired with so-called K-gas, a natural gas from the near Khursaniyah gas field which has a relatively low calorific value. Siemens and Saudi Aramco have been jointly testing the suitability of the F-class gas turbine for this special type of fuel.
