Utility companies and gas turbine manufacturer alike are working diligently to improve Gas Turbine Combined Cycle (GTCC) efficiency in order to reduce fossil fuel consumption as well as CO2 emissions.
Tohoku Electric Power Co., Inc. started operating large size GTCC in 1984 with Mitsubishi D series gas turbines. Since then, the company has lead the application of first of class Mitsubishi gas turbines. The company applied the first M701G gas turbine in 1999 and this successful experience was followed in 2010 with the single-shaft Sendai GTCC featuring the first M701F4.
The M701F5 was introduced in 2011 by Mitsubishi Hitachi Power Systems, LTD. (MHPS) and Tohoku Electric pioneered one more time its application at the No.3 Shin-Sendai Power Plant in 2015.
The M701F5 features the combination of technologies verified in other gas turbine frames. This paper introduces the feature of the M701F5 gas turbine including its technologies and verification results.
