Best gasBest gas--fired plant in 2010fired plant in 2010

In December 2010 M701F4 GTCC plant recognized the

Project of the Year by Power Engineering magazine.

“Best Gas-fired Projects Project of the Year. Sendai thermal power station replacement projects,

Shichigahama Town, Japan”

Tohoku-Electric Power Co. wins the Project of the Year for best gas fired project with its 446 MW Sendai

No.4 combined-cycle plant. This plant, located in Shichigahama Town, Japan, replaced three existing 175 MW

coal fired plants that started commercial operation more than 50 years ago. The new and cleaner single

shaft combined cycle plant burns natural gas with 60 percent CO2 emissions reduction and considerable

NOx emissions reductions.

The new plant operating mode is based on a Daily Start and Stop (DSS) duty cycle to compensate the

load variability in the area.

The plant is one of the first applications of the Mitsubishi M701F4, Mitsubishi Heavy Industries’ (MHI’s)

most recent 50Hz class gas turbine upgrade. This machine incorporates changes to six compressor stages

to increase air flow by 6 percent..”
