Overall Design

H-100 Series units are the world's largest capacity two-shaft gas turbines based on a great deal of experience in manufacturing gas turbines and achievements in the development of the H-25 and H-15 Series. They achieve high efficiency as part of combined cycle plants with heat recovery boilers, co-generation systems or other combined cycle power plants. The H-100 Series features simple cycle gas turbine output of 105 MW to 116 MW and an output range of 150 MW to 350 MW in combined cycle. As two-shaft gas turbines, they are suited to mechanical drive applications.

Heavy duty design: A heavy and highly reliable structure designed in consideration of ease of maintenance and long-term continuous operation
High efficiency: High performance in various power generation cycles (simple, combined and co-generation)
Package type: Easy to carry and install
The series is applicable not only for power generation but also for mechanical drive
