Coal-Fired Plants in Japan
Haramachi
Location: Fukushima
Operator: Tohoku Electric Power Co Ltd
Configuration: 2 X 1,000 MW
Fuel: bituminous coal, oil
Operation: 1997-1998
Boiler supplier: MHI, Babcock-Hitachi
T/G supplier: Toshiba, Hitachi
EPC: Taihei Dengyo Kaisha
Quick facts: These two USC units were among the most advanced in the world at completion. The project was first mooted in January 1977 and site prep began in Mar 1990. Ground-breaking on Unit-1 was in Feb 1993 and it went commercial on 11 Jul 1997. Unit-2 went commercial on 3 Jul 1998 with slightly higher steam temperatures. Haramachi TPS was considerably damaged by the tsunami resulting from the Great East Japan Earthquake of Mar 2011. Damage included submerged electric systems, plus machinery, and equipment on the first and second floors of the turbine building, destruction of the ESPs, and collapse of coal unloaders. In the restoration work, as many as 5,000 workers were brought in and some work continued in two shifts, 24hrs/day. The unti restarted in April and March 2013, respectively. Photo was talen on 16 Apr 2011. A Power Plant Trading Card was made for this plant.
