Iran’s gas supply network, covering over 95% of the country, is among the world’s most extensive, surpassing the U.S. and Russia’s coverage. Its pipelines stretch significantly more than the distance to the Moon, showcasing Iran’s engineering capabilities and energy sector importance. While the network supports economic development and energy security, a projected gas deficit of 373 million cubic meters by 2027 highlights the need for ongoing investment and adaptation to market competition and environmental regulations. Despite challenges, Iran’s infrastructure positions it as a key regional energy player, crucial for both domestic needs and international relations.
