Siemens Energy Invests $1.6 Billion In Renewable Energy Project
Located in the Western and Central regions of the Kingdom, the new power plants, Rumah 2 and Nairyah 2, will figure among the world’s largest combined-cycle power plants.

Siemens energy has secured a US $1.6 billion project to provide key technologies for the Rumah 2 and Nairyah 2 gas-fired power plants in Saudi Arabia. Harbin Electric International will be the EPC contractor for the project.
Located in the Western and Central regions of the Kingdom, Rumah 2 and Nairyah 2 will figure among the world’s largest combined-cycle power plants. They will replace aging oil-fired stations, reducing CO2 emissions by up to 60% compared to traditional oil-based power generation.
The plants will add 3.6 gigawatts of power to the national grid, which will be enough to supply around 1.5 million homes.
Siemens Energy will supply six SGT6-9000HL gas turbines, four SST6-500 steam turbines, eight SGen6-3000W generators, two SGen6-2000P generators and auxiliary equipment. Each site will generate approximately 1.8 gigawatts of electricity.
Core components of the power plants will be manufactured at the Siemens Energy Hub in Dammam.
Rumah 2 and Nariyah 2 will initially be integrated into the grid in simple cycle mode in 2027 and will transition to full operation as combined-cycle power plants by 2028. The project also includes long-term maintenance agreements to support the plants’ operational reliability over the next 25 years.
