Siemens Energy and GE Vernova have announced major contracts to support the construction of four large CCGT power units in Saudi Arabia. The gas-fired projects are the Taiba 1 and 2, located in western Saudi Arabia about 60 miles southeast of Madinah city, and Qassim 1 and 2 sited in the central region about 20 miles southeast of Buraydah city.
On the one hand, GE Vernova has secured an order to supply six 7HA.03 gas turbines and two 7E.03 gas turbines to the Taiba 1 and Qassim 1 projects rated 1.9 GW each from the engineering, procurement, and construction (EPC) company SEPCOIII Electric Power Construction. In addition, it signed a 21-year service agreement to support plant operations with National Operations & Maintenance Company (NOMAC), an ACWA Power subsidiary. The facilities are expected to deliver up to 3.8 GW of electricity to the grid in total once they become operational in 2027, enough to power approximately 1.2 million homes in Saudi Arabia.
On the other hand, Siemens Energy will provide its HL-class turbines in combination with steam turbines and generators to the Taiba 2 and Qassim 2, with China Energy International being the EPC and contracting partner for the projects. Siemens has also entered a 25-year maintenance contract for both power plants in a US$1.5bn deal. The facilities are expected to generate nearly 2 GW each to the national grid, and to be connected to the grid in simple-cycle mode in 2026, to later transition towards combined-cycle operation in 2027.
Saudi Arabia has a goal to generate about half its electricity from renewable energy sources and half from gas by 2030, and to reach net-zero emissions of carbon by 2060 by expanding its use of modern and efficient gas-fired power plants, in combination with carbon capture and storage.
