The initiative to boost domestic value through programs like Made in Saudi is further promoting the local production of boilers and supply chain components, increasing domestic industrial involvement and decreasing dependence on foreign imports. Saudi Arabia power plant boiler market by technology is divided into subcritical, supercritical and ultra- supercritical. In Saudi Arabia, the advancement of thermal power technology is influenced more by fuel strategies, flexibility of systems, and integration with industries rather than the evolution of coal-based steam cycles found in countries dependent on coal. Traditionally, subcritical steam technology was prevalent in standard thermal plants utilizing steam cycles, particularly in oil- and gas-powered utility boilers and industrial cogeneration systems. These setups were affordable, easier to engineer, and well-suited for the abundant and cost-effective oil and natural gas fuels. Nevertheless, the modern approach to expanding power generation in the Kingdom has moved away from the older subcritical steam configurations to efficient combined-cycle gas turbine CCGT systems, which effectively bypass the established subcritical/supercritical categorizations by incorporating gas turbines along with heat recovery steam generators.

The technologies of supercritical and ultra-supercritical, usually linked to coal-generated power, have limited applicability in Saudi Arabia’s electricity sector due to the lack of coal in its fuel supply. These technologies aim to enhance efficiency and lessen emissions in coal steam cycles; however, Saudi Arabia’s energy model favors natural gas, readiness for hydrogen, and comprehensive cogeneration systems instead of coal-based steam production. Rather than using supercritical coal boilers, Saudi Arabia achieves elevated efficiency levels through modern gas turbines, digital control of combustion, recovery of waste heat, and extensive cogeneration within refineries and industrial areas. Saudi Arabia power plant boiler market by fuel type is divided into coal based, gas based, oil based and other fuel based. The thermal power framework in Saudi Arabia is primarily based on gas and oil, with no contribution from coal in the national power generation landscape. Coal is not utilized in Saudi utility power production due to its unavailability, ecological strategies, and long-term decarbonization goals.

Therefore, the Coal-Based section is entirely missing from the Saudi market. The leading segment is Gas-Based thermal generation, which is the foundation of Saudi Arabia’s contemporary power infrastructure. Natural gas powers extensive combined-cycle facilities, industrial cogeneration operations, and utility-scale generation plants across the nation. Gas-powered plants are preferred because of their high efficiency, comparatively lower emissions compared to oil, quick ramping capabilities, and compatibility with hydrogen blending. The national plan consistently emphasizes gas as a substitute for liquid fuels, making gas the primary transition fuel for decarbonization efforts and maintaining grid stability. While Oil-Based thermal generation remains in the picture, it is in a declining state.

Historically, Saudi Arabia depended significantly on crude oil and heavy fuel oil for electricity, especially in steam boilers and open-cycle turbines. However, issues of economic inefficiency, the need to maximize export values, and concerns over emissions have prompted policies to limit the use of oil in power generation. Currently, oil-powered plants mainly function in backup, peak load, or remote system capacities, with ongoing initiatives replacing oil units with gas alternatives. The Alternative Fuel Based sector is gaining prominence and is crucial for strategic development. This area encompasses hydrogen, ammonia, synthetic fuels, recycling of waste heat, and hybrid systems linked to renewable energy. Saudi Arabia power plant boiler market by capacity is divided into below 400 MW, 400 to 800 MW and above 800 MW.

The thermal power capacity landscape in Saudi Arabia showcases its function as a vast, industrial energy framework, exhibiting strong presence across all capacity ranges. The category of Under 400 MW is primarily composed of industrial boilers, cogeneration systems, desalination-associated plants, and local utility facilities. These systems are commonly used in refineries, petrochemical plants, water desalination facilities, industrial areas, and remote grid networks. Their main roles include providing process steam, generating local electricity, and supporting the grid, rather than serving as national baseload energy sources.
