What is the backbone of the Iranian energy landscape?

NIGC safely operates gas pipelines with Siemens technology. Integrated security systems support in supplying Iran's natural resource efficiently to every corner of the country.
Sustainable Energy

A backbone of Iran’s energy landscape

Did you ever ask yourself how the gas you heat and cook with is transported from the sea to your home? After extraction from offshore sites Iran’s natural and precious resources are transported via gas pipelines throughout the country.

Being one of the backbones of the Iranian energy landscape, TC50 and IGAT5 pipeline supplies natural gas deriving from Bushehr in the Persian Gulf.

The National Iranian Gas Company (NIGC) runs the TC50 and IGAT5 pipeline which is with 1800km one of the longest in Iran. Since 2010, the pipeline has been transporting natural gas that flows from Bushehr in the south through several provinces, including Shiraz, Isfahan, Qom, and Qazvin. 72 units consisting of Siemens gas turbines and centrifugal gas compressors are distributed over 17 stations that pump the gas into the Iranian pipeline. While the first few units were manufactured in Sweden and Germany, OTC was able to quickly take over production for a large portion of the components in Iran. To ensure reliable, efficient and flexible operation Siemens provides engineering expertise to the Iranian pipeline market. With high-technology for mechanical, electrical and digital solutions we cover end-to-end solutions, all certified to be compliant with any environmental and safety standards. Field-proven compressors, gas turbines, electric drives and motors with state-of-the-art control systems and integrated electrification and instrumentation for every application are incorporated. Customers like NIGC benefit from comprehensive engineering expertise and proven experience. In order to make customers ready for future challenges, Siemens also offers digitalization, noise reduction and low-emission power supply solutions that help reducing capital expenditure. Thanks to embedded security and monitoring solutions customers enjoy a peace-of-mind because their assets are protected and operate at the lowest level of lifecycle costs. Siemens supports NIGC with supplying gas to homes in every corner of the country, as well as to power plants which feed the power grid and factories enabling manufacturing of Iranian goods. Siemens portfolio is completed by the reliable local support during long-term operations and trainings for pipeline operators.


Distributing Iran’s resources to every household

After production, natural gas needs to be transported to all the places where it is needed. High-technology drives and compressors installed in a network of gas pipelines forward the country’s precious resource across its vast geography. The National Iranian Gas Company (NIGC) collaborated with Siemens to deliver the technology, enable its local production, and allow access to natural gas for Iranians across the country.
