Case Study

Seoul Metro joins the green approach.

The SCADA Movicon.NExT by Emerson has been chosen
for the improvement of energy efficiency of the Seoul subway
network in South Korea.

Among its various customers, Inter Electric boasts Seoul Metro, which is not only one of the most representative public institutions in South Korea, as it is the company that manages the metro network in the capital and surrounding areas, but also aims to develop urban transport and improving public well-being. The Seoul subway has 22 operating lines and 707 stations, including the Korail lines (Korea Railroad Corporation – the most important South Korean railway company) and those for commuter traffic. It includes 537.4 km of metro lines and is a total of 1131.5 km long including suburban railways. The Seoul metropolitan system is one of the most used urban transport systems in the world, with over eight million daily journeys. The network serves Seoul, Incheon, Gyeonggi-do, the north of Chungcheongnam-do and the western part of Gangwon-do.

The whole project was also made possible thanks to the application flexibility of Movicon.NExT and the constant availability of Emerson technical staff, who actively supported us both in the pre-sale phase during the formulation of the project specifications and in the after-sales phase by providing us with examples and always useful and punctual suggestions that have allowed us a rapid implementation of the project.

Sang Hyun Jeon, Inter Electric Executive Director

Seoul Metro’s request was to provide a system that was easy to use and reliable for the collection and monitoring of energy data from 277 stations, 80 substations and 16 depots and that supported various protocols, including Modbus and BACnet. In addition, a web interface was required. This would allow Seoul Metro staff to collect third-party data from external systems such as DR, Weather, and ERP.
