Siemens Energy has secured a $1.6 billion contract to supply key technologies for the development of the Rumah 2 and Nairyah 2 gas-fired power plants in Saudi Arabia. The project, in collaboration with Harbin Electric International as the EPC contractor, is a significant step in the Kingdom’s energy transition, enhancing both power generation capacity and efficiency.
Project Details: Rumah 2 and Nairyah 2 Power Plants
Located in the western and central regions, the Rumah 2 and Nairyah 2 plants will add 3.6 gigawatts to Saudi Arabia’s national grid, providing electricity to approximately 1.5 million homes. These plants are set to replace aging oil-fired facilities, improving efficiency and reducing environmental impact. Siemens Energy has also committed to long-term maintenance agreements, ensuring operational reliability for the next 25 years.
Rumah 2 and Nairyah 2 will rank among the world’s largest combined-cycle power plants. By replacing traditional oil-based power generation, they are expected to cut CO2 emissions by up to 60%. Additionally, the plants are designed to accommodate future carbon capture and storage technologies, supporting Saudi Arabia’s long-term net-zero emissions goal by 2060.
Siemens Energy’s Scope of Work
With the Chinese Contractor Harbin Electric International as the main EPC contractor, Siemens will be responsible for supply the power generation systems for both plants, including:
- six SGT6-9000HL gas turbines,
- four SST6-5000 steam turbines,
- eight SGen6-3000W generators,
- and two SGen6-2000P generators, along with associated auxiliary equipment;
It is understood that the balance of plant works are under Harbin Electric, which with over 70 years of track record, has established itself as a recognized expert in hydropower, nuclear power, coal-fired power, gas-fired power, and wind power projects.
A crucial aspect of this project is the manufacturing of core components at the Siemens Energy Dammam Hub, which is currently expanding to boost local production capacity. This move aligns with Saudi Arabia’s broader objective of strengthening domestic capabilities in the energy sector.
Each plant will contribute approximately 1.8 gigawatts of electricity to the grid, which is sufficient to power around 3.16 million homes, ensuring stable and efficient power generation.
Leadership comments on the contract
“Supplying key technologies for the Rumah 2 and Nairyah 2 power plants directly supports Saudi Arabia’s energy transition and its goal of achieving net zero emissions by 2060,” said Ahmed ElSerry, Head of Gas Services Sales, Siemens Middle East. “By manufacturing critical components at our Siemens Energy Dammam Hub, this project further strengthens local production capabilities and builds expertise within the Kingdom, contributing to a more resilient energy sector.”
Rumah 2 and Nairyah 2 Power Plants - Construction Program
The Rumah 2 and Nairyah 2 power plants will be integrated into the grid in simple-cycle mode by 2027. They will transition to full combined-cycle operation the following year, maximizing efficiency and sustainability.
According to Siemens, this contract reinforces Siemens Energy’s established presence in Saudi Arabia’s Independent Power Producer (IPP) market. Following the success of previous projects such as Taiba 2 and Qassim 2—which added a combined 4 gigawatts to the national grid—Siemens Energy continues to contribute to the modernization and expansion of the country’s energy infrastructure.
