Despite these complexities, the Iranian Gas Transmission Company set new records and ensured uninterrupted gas supply throughout the season.

Last year, the company played a vital role in maintaining stable energy supply, ensuring no household experienced gas cuts during the harsh winter. In the first half of 1403, meticulous planning and round-the-clock efforts by employees across 10 operational regions enabled extensive preparations.

These included maintenance, repairs, and monitoring of over 40,000 kilometers of high-pressure gas pipelines by 62 operational centers, along with servicing 95 gas pressure boosting stations and 350 turbo-compressors.

Key activities included:

- Complete overhauls of 48 gas turbines 

- Smart pigging and cleaning of 5,000 kilometers of pipelines 

- Replacement of 133,000 square meters of pipeline coating 

- Inspection, monitoring, and repairs at 1,100 points along main pipelines 

- Leak detection operations across 50,500 kilometers 

These preventive measures significantly enhanced the company’s readiness for winter challenges.

 Balancing supply-demand

Over 70% of Iran’s sweet gas is produced in the south, primarily at the South Pars Gas Refinery, while the same volume is consumed in the northern half of the country. This highlights the critical role of the Iranian Gas Transmission Company in moving vast quantities of gas from the warmest southern regions to the coldest northern areas—requiring an extensive network, well-maintained facilities, and dedicated personnel. Their efforts ensure warmth for households and keep the nation’s industries running.

 Record-breaking gas transmission 

Early cold weather in November 2024 triggered a sharp rise in household gas consumption, with temperatures dropping by up to 15°C. On December 8, the company set its first record of the year, transmitting 862 million cubic meters (mcm) of gas in a single day—surpassing the previous record of 855 mcm set in late January 2023.

Further milestones included:

- Total annual transmission exceeding 282 billion cubic meters (bcm)—an increase of 6 bcm compared to 2023 

- A new daily record of 880 mcm on February 2 

- Seven national gas transmission records broken during peak winter 

- Simultaneous operation of 208 turbo-compressor units for the first time 

- Reactivation of 20 pressure boosting stations without backup units 

Gas production also rose by 30 mcm per day to offset energy shortages during the prolonged cold spell.

 Round-the-clock preparedness

Key measures ensuring stable transmission included:

- 24/7 operational readiness across 10 regions 

- Field inspections by the CEO, particularly in cold regions 

- Deployment of 50 emergency teams to remote and harsh locations 

- The public awareness campaign "2 Degrees Lower" to promote consumption management 

 Overcoming crises, extreme cold 

The company faced multiple technical crises during winter, all resolved through swift action:

- Ahvaz’s Shahid Mostafavi Gas Facility: Restored within 24 hours after an outage, preventing disruptions in Khuzestan Province.

- Rasht Facility: Technical issues resolved by Region 9 teams, stabilizing pressure in East Azerbaijan.

- Sarab Pressure Boosting Station: Reactivated after years of inactivity by Region 8 teams, alleviating gas pressure drops in Ardabil.

- Qom’s Sarajeh Facility: Emergency turbine replacement ensured continued operations.

Had these critical actions not been taken, parts of Iran could have faced severe gas shortages.

 Historic cold snap in February 

A nationwide freeze brought subzero temperatures, straining gas pressure—especially in northern and northwestern provinces. Ardabil, at the end of the transmission line, faced -20°C temperatures, heavy snow, and ice. Region 8 teams successfully reactivated the long-dormant Sarab facility, knowing every second counted for thousands of households.

 A winter of achievements 

The successful transmission of 282 bcm of gas in 1403 was made possible by the relentless efforts of employees in both headquarters and operational regions. Key factors included strategic management, optimal pressure boosting station deployment, and precise gas flow coordination.

Peyman Khazraei, CEO of the Iranian Gas Transmission Company, praised his team during a field visit:

"My colleagues’ dedication is beyond commendable—it goes above and beyond duty. They work tirelessly to ensure people’s comfort and well-being."

Winter 1403 was a challenging yet triumphant season for the company. By overcoming crises, setting records, and ensuring uninterrupted gas supply, the company upheld its vital role in Iran’s energy stability—thanks to the unity, sacrifice, and hard work of its employees. Millions of families nationwide enjoyed a warm winter, and the country’s economic cycle remained uninterrupted.
