    Mitsubishi Hitachi Power Systems, Ltd. (MHPS) has continually contributed to global environmental protection, as well as to the stable supply of energy through the development of gas turbines based on abundant operational achievements and advanced technology research efforts. More recently, we have developed the M501J capable of achieving the world's first turbine inlet temperature of 1,600°C and even a thermal efficiency in gas turbine combined cycle (GTCC) of 61.5% or more, using developments attained in the national "1,700°C-Class Ultrahigh- Temperature Gas Turbine Component Technology Development" project we joined in 2004. Demonstrative operation started in 2011, using the demonstration equipment located within our Takasago Machinery Works, for later implementation of the accumulation of our global sales and operational record. Furthermore, based on the core technologies adopted in the M501J (60Hz unit), the M701J as the 50-Hz unit of the J Series was developed, and its shipment was completed after being tested at the factory. This paper relates to how these state-of-the-art high-efficiency gas turbines are developed and operated.
