Hirono
Location: Fukushima
Operator: Tokyo Electric Power Co
Configuration: 4 X 600 MW, 2 X 1,000 MW,
Fuel: heavy oil, crude oil, bituminous coal
Operation: 1980-2013
Boiler supplier: IHI, MHI, Babcock-Hitachi
T/G supplier: Toshiba, Hitachi, MHI, Melco
EPC: TDKL
Quick facts: This coastal plant is 3km north of Hirono-machi, in Futaba-gun. It was the closest Tepco thermal plant to the epicenter of the the Mar 2011 Tohoku Earthquake. Only Units 2&4 were online at the time, but all turbine buildings were flooded and there were large amounts of debris on the site. After months of work, all 5 units were re-started by 16 Jul 2011. Units 5&6 are coal-fired, USC sets with 48" last-stage blades. Construction on Unit-6 began on 1 Dec 2008 and it went commercial on 3 Dec 2013. Design thermal efficiency is 45.2%, said to the the highest in the world at the time.
