In 2012, K-water constructed 41 new hydropower generators (50 MW) as part of "The Four Major Rivers Restoration Project". K-water has designed and established a remarkable integration system for the project. The system consists of 1 Headquarter, 5 Control Centers and 16 power plants. The main features of the system are redundant network service, hot-standby function for main servers, triple network circuits, intrusion prevention system for anti-viruses, real-time measuring of generation, partial discharge monitoring of rotors, etc. Moreover, it is not an independent system but rather a working as a part of GIOS.
