Saudi Arabia will burn more imported fuel oil for power this summer due to gas supply loss
Due to reduced natural gas supplies, Saudi Arabia anticipates increased use of imported fuel oil for electricity generation this summer, according to analysts. The drop in natural gas stems from the closure of oilfields after the Iran war, which curtailed the nation’s oil exports.
The rise in fuel oil consumption in power plants, coinciding with peak summer electricity demand for cooling, represents a setback to Saudi Arabia’s efforts to transition to cleaner energy sources.
The world’s leading oil exporter has been compelled to halt over 3 million barrels per day of oil production following an Iranian blockade of the Strait of Hormuz, which disrupted crude exports from Ras Tanura. This disruption has subsequently reduced the associated gas output.
Despite the commissioning of the Jafurah gas field in December, gas production decreased to 10.5 billion cubic feet per day in the first quarter, down from 10.7 bcfd in the fourth quarter of 2025, according to Saudi Aramco’s recent quarterly earnings report.
To compensate for the gas shortfall at power plants, Aramco boosted its fuel oil imports to roughly 1.7 million tons (360,000 bpd) in April, an 86% year-over-year increase, according to Vortexa data. The majority of these imports were delivered to terminals linked to power and desalination plants, including Jeddah South and Shuqaiq Steam.
Rahul Choudhary, vice president of oil & gas research at Rystad Energy, stated that the substantial surge in fuel oil imports indicates a rise in oil consumption compared to last year.
Saudi Arabia’s power demand typically escalates from April, reaching its peak in August, thereby increasing the use of crude, high-sulphur fuel oil (HSFO), and gas in power plants. Choudhary noted that the burning of crude and fuel oil for power could exceed 1 million barrels per day this summer. This would undermine efforts to increase gas and renewable energy use, reversing the low of 991,000 bpd observed in 2025.
Aramco is expected to burn less crude for power this summer, as it prioritizes crude exports, primarily Arab Light, via the East-West pipeline to the Red Sea port of Yanbu, and due to HSFO’s lower cost compared to Saudi crude.
Last year, Saudi Arabia’s direct crude burn averaged 593,500 barrels per day from June to September, according to data from the Joint Organisations Data Initiative (JODI).
Analysts hold differing views on the precise amount of crude Saudi Arabia will use for power generation this summer.
Wood Mackenzie anticipates a decrease of 5,000 to 15,000 bpd in crude burn from an average of 629,000 bpd between June and August 2025.
Jayadev D, an oil research analyst at WoodMac, said that every barrel of Arab Light crude used domestically results in a significant loss of export revenue.
Rystad Energy estimates that crude consumption for power will average approximately 540,000 to 550,000 bpd this summer.
Koen Wessels, head of demand at Energy Aspects, expects Saudi Arabia to burn more crude this summer than in 2025, constrained by how much crude supply it can divert to Red Sea ports. Energy Aspects forecasts that Hormuz transits will remain disrupted through the end of May, with a 50% recovery on pre-war tonnage in June, 60% in July, and 70% in August, Wessels said.
