Siemens Energy to advance Saudi Arabia’s energy transition with new power plants

Siemens Energy has been awarded a USD 1.6 billion project, with Harbin Electric International as the EPC contractor, to provide key technologies for the Rumah 2 and Nairyah 2 gas-fired power plants in Saudi Arabia. The project includes long-term maintenance agreements to support the plants’ operational reliability over the next 25 years.

Core components for the power plants will be manufactured at the Siemens Energy Dammam Hub, which is currently expanding to increase local production capacity and support Saudi Arabia’s energy sector.

Rumah 2 and Nairyah 2 will rank 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. Additionally, the plants are being designed to be compatible with advanced CO2 capture and storage technologies, supporting Saudi Arabia’s long-term emissions reduction goals.

Siemens Energy will supply six SGT6-9000HL gas turbines, four SST6-5000 steam turbines, eight SGen6-3000W generators, two SGen6-2000P generators, and associated auxiliary equipment, with each site generating approximately 1.8 gigawatts of electricity.

This order further strengthens Siemens Energy’s established presence in Saudi Arabia’s Independent Power Producer (IPP) market, solidifying its role in delivering a significant share of Saudi Arabia’s modern power generation. Building on the success of previous projects like Taiba 2 and Qassim 2 – which together add 4 gigawatts to the national grid – Siemens Energy continues to drive local manufacturing expansion and infrastructure modernization, playing a key role in the country’s energy sector.

Rumah 2 and Nairyah 2 will initially be integrated into the grid in simple cycle mode in 2027, transitioning to full operation as combined-cycle power plants by the following year.
