Siemens Energy has been awarded a $1.6 billion project, with Harbin Electric International Co., Ltd. as the EPC contractor, to provide key technologies for the Rumah 2 and Nairyah 2 gas-fired power plants in Saudi Arabia, the company announced on Wednesday.

Located in the western and central regions, the plants will add 3.6 gigawatts of power to the national grid – enough to supply around 1.5 million homes.

The project includes long-term maintenance agreements to support the plants' operational reliability over the next 25 years, it said.

Rumah 2 and Nairyah 2 will rank among the world's largest combined-cycle power plants. They will replace aging oil-fired stations, reducing carbon dioxide emissions by up to 60 percent compared to traditional oil-based power generation. Additionally, the plants are being designed to be compatible with advanced carbon dioxide capture and storage technologies, supporting Saudi Arabia's long-term emissions reduction goals.

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.
