Siemens Energy has been awarded a $1.6 billion contract to supply essential technologies for the Rumah 2 and Nairyah 2 gas-fired power plants in Saudi Arabia. The company will collaborate with Harbin Electric International, the project’s EPC contractor, to deliver these critical energy assets.
Set to be built in the central and western regions of Saudi Arabia, the two plants will add 3.6 gigawatts of electricity to the national grid, powering approximately 1.5 million homes. Siemens Energy will also provide long-term maintenance services, ensuring the plants operate reliably for at least 25 years.
A significant portion of the equipment will be locally manufactured at Siemens Energy’s Dammam Hub, which is undergoing expansion to boost production capacity and support the Kingdom’s growing energy demands.
Once completed, Rumah 2 and Nairyah 2 will rank among the world’s largest combined-cycle power plants, replacing older oil-fired units and cutting CO₂ emissions by up to 60% compared to traditional oil-based plants. Importantly, these new plants are also being designed to integrate future carbon capture and storage (CCS) technologies, aligning with Saudi Arabia’s goal of achieving net-zero emissions by 2060.
“This project is a key step toward supporting Saudi Arabia’s energy transition and sustainability targets,” said Ahmed ElSerry, Head of Gas Services Sales for the Middle East at Siemens Energy. “By producing critical components locally at our Dammam Hub, we are not only contributing to the Kingdom’s energy goals but also building local expertise and manufacturing capabilities,” he added.
As part of the contract, Siemens Energy will supply a wide range of equipment, including six SGT6-9000HL gas turbines, four SST6-5000 steam turbines, eight SGen6-3000W generators, two SGen6-2000P generators, and various auxiliary systems. Each plant is expected to generate about 1.8 gigawatts of electricity.
This new order strengthens Siemens Energy’s role in Saudi Arabia’s Independent Power Producer (IPP) market, reinforcing its partnership with the Kingdom following recent major projects like Taiba 2 and Qassim 2, which together add 4 gigawatts of capacity to the grid.
Rumah 2 and Nairyah 2 are scheduled to begin operations in simple cycle mode by 2027, before transitioning to combined-cycle mode in 2028, contributing significantly to the modernization of Saudi Arabia’s power infrastructure.
