The H-100 gas turbine was originally named “H-80” and, as of April 1, 2015 has been re-named “H-100″ to better reflect its capacity class. The H-100 was introduced in January 2010, when the first unit went into commercial operation at the Shin-Oita Power Station of the Kyushu Electric Power Company, Inc. in Japan.

 In order to meet the North American market demands for flexibility and low NOx emissions, several modifications of the original H-100 have been implemented that make the H-100 an ideal candidate for peaking and load stabilization applications: A single digit NOx combustor is available that was adopted from MHPS larger, advanced 501G/J gas turbines, and a fast-start option allows a 10 minute gas turbine start from ignition to full load.

 Due to its high exhaust energy, the H-100 is very suitable for combined cycle and cogeneration applications and achieves combined cycle plant ISO efficiencies over 56%, which is best-in-class for mid-size combined cycle plants. Moreover, the two-shaft design and associated high starting torque and variable speed range of the H-100 makes it an ideal driver for industrial equipment, such as liquefied natural gas refrigeration compressors.
