Houshang Seydali, NIGC’s director of gas distribution coordination, said the expansion of the gas network has been achieved despite significant technical and geographical challenges, particularly in mountainous and remote regions. He noted that difficult terrain, rocky landscapes and environmental protection requirements have increased project costs, as pipeline routes are often adjusted to avoid damaging forests and natural habitats.

Seydali said engineers have focused on strengthening infrastructure to improve resilience against natural disasters. Following heavy rainfall and flooding in Ilam and Golestan provinces in late 2025 and early 2026, exposed pipeline sections were quickly reinforced to prevent future disruptions.

According to Seydali, more than 99% of Iran’s cities — 1,266 in total — are connected to the gas network. Rural gas coverage has reached about 88% and is expected to rise to 90% as ongoing projects are completed, bringing overall national coverage to approximately 96%.

He said Iran is revising its energy strategy in response to growing supply-demand imbalances. The company plans to complete gas projects that are already more than 50% to 60% finished, while alternative energy sources such as electricity and solar power will be considered for areas that remain unconnected.

Seydali added that government agencies are required to meet 20% of their electricity needs through solar energy. Major solar projects are currently underway in Razavi Khorasan and Isfahan provinces, alongside smaller rooftop installations across the country.

He also highlighted the social benefits of rural gas access, saying improved energy services have contributed to economic activity and encouraged some residents to return to rural communities. At the same time, he urged households to improve energy efficiency and avoid excessive gas consumption, particularly during winter months when demand places pressure on supplies.
