TEHRAN – Iran supplied more than 22 billion liters of liquid fuel to power plants in the Iranian year 1403 (March 2024–March 2025), a 40 percent increase from the previous year, the Oil Ministry said.

The ministry said stable fuel supply became a top priority at the start of President Masoud Pezeshkian’s administration, given low inventories and rising winter demand.

Average daily deliveries of natural gas, gasoil and fuel oil to power plants reached the equivalent of 272 million cubic meters of gas, up 21 million cubic meters from the previous year.

To boost supply, the ministry expanded transfer capacity from southern refineries to central and northern regions. The first phase of a 26-inch pipeline between Bandar Abbas and Rafsanjan was commissioned ahead of schedule in autumn 2024, adding 13 million liters per day in throughput and eliminating the need for 500 fuel tanker trucks. Six power plants were newly connected to the pipeline system, with three more to follow by year-end.

In logistics, the ministry added 3,700 tankers and rail wagons to the fuel transport fleet, supported by incentive payments to carriers, which helped accelerate deliveries during the winter peak.

Despite public concerns over empty storage tanks, the ministry said power plant reservoirs — with a useful capacity of 3.3 billion liters — were filled and emptied nearly four times during the year. It attributed temporary dips in stocks to surging consumption rather than shortfalls in supply.

On March 3, 2025, Iran set a one-day record by delivering 107 million liters of liquid fuel to power plants, including 72 million liters of gasoil and 35 million liters of fuel oil.

Average gasoil deliveries reached 37.4 million liters per day, up 10 million liters (37 percent) from the previous year, while fuel oil supplies averaged 28.6 million liters per day, up 8.6 million liters (43 percent).
