The stage 2 of the Group 4 of Futtsu Thermal Power Plant (the Director: 
Kenji Matsuzaki, place: Shintomi 25, Futtsu City, Chiba Prefecture, rated 
capacity: 507 MW) of TEPCO has stopped the power generation at 9:58 am on 
February 21, since on the same day decrease in exhaust gas temperature of 
the gas turbine was confirmed when it was in operation. 
After the cooling of the gas turbine was completed, we inspected it and 
the damage on the exhaust duct was confirmed. Therefore, we will set out a 
repair work of the damage. 
 
Since the supply capacity is 51,800 MW today, reserve rate of 17.7% is 
likely to be secured.
