Project Brief

As a key initiative under Saudi Vision 2030, this project aims to improve the nation’s grid stability and optimise its energy mix. It adopts the advanced H-class heavy-duty gas turbine combined cycle technology, featuring three GE 7HA.03 gas turbines, one 7E.03 gas turbine, three heat recovery steam generators, and one steam turbine to achieve a total installed capacity of 1,800 MW.

This significantly enhances energy efficiency while reducing carbon emissions. Boasting a modular design, high-temperature alloys and corrosion-resistant materials, and a multi-layer protection system, the project ensures the stable work of devices and the safety of operators. Additionally, it utilises high-reflectivity, weather-resistant building materials, effectively mitigating the heat island effect and harmonising with the surrounding natural environment.

Project Innovation/Need

This project greatly improves the efficiency, adaptability, and sustainability of energy infrastructure by integrating cutting-edge technologies and systems. Taking the world’s leading H-class heavy-duty gas turbine combined cycle technology as the core, it boasts a thermal efficiency of over 60%, achieving more efficient energy conversion and lower carbon emissions.

The project, capable of dual-fuel operation, enables flexible switching between natural gas and other clean fuels for better adaptability. It also incorporates interfaces for carbon capture, laying the technical groundwork for future net-zero emissions. Further innovations include a modular layout and an integrated design that optimises space utilisation, enhances construction efficiency, and facilitates convenient operation & maintenance.

Design Challenge

To address the challenges (intense heat, strong solar radiation, and wind erosion) posed by desert conditions, the project employs high-reflectivity and weather-resistant building materials to enhance structural durability and environmental adaptability.

Faced with intractable spatial organisation arising from complicated industrial processes, it adopts a modular layout and an integrated design to optimise circulation and workflow, improving operational continuity and convenience. Considering future carbon-neutral requirements, the project features interfaces for carbon capture, supporting integration with clean energy technologies for upgrades. Additionally, it utilises a consistent material language and a low-saturation colour palette, ensuring visual harmony between industrial infrastructure and the local natural environment.

Sustainability

Equipped with the H-class heavy-duty gas turbine combined cycle technology, this project features a remarkable thermal efficiency exceeding 60%, and substantially decreases carbon emissions per kilowatt-hour of electricity generated. It also boasts interfaces for carbon capture, supporting future upgrades for further decarbonization.

Recyclable high-temperature alloys and corrosion-resistant materials applied to critical components, coupled with water recycling systems and exhaust gas purification units, effectively reduce both resource consumption and environmental impact. This project enhances the nation’s grid stability, accelerates the transition to green, low-carbon energy sources, fosters local high-tech manufacturing and engineering capabilities, and creates more employment opportunities, achieving a harmonious unity of economic growth, social development, and environmental sustainability.
