Press Release (Aug 20,2011)
Status of TEPCO's Facilities and its services after the Tohoku-Chihou-Taiheiyou-Oki Earthquake (as of 9 AM, August 20)
Due to the Tohoku-Chihou-Taiheiyou-Oki Earthquake which occurred on March 
11, 2011, TEPCO's facilities including our nuclear power stations have 
been severely damaged. We deeply apologize for the anxiety and 
inconvenience caused.
With regard to the accident at Fukushima Daiichi Nuclear Power Station, on 
April 17, we have compiled the roadmap towards restoration from the 
accident and then we updated the progress status of roadmap considering 
the current situation, on July 19. Accomplishment of the Step1 target 
"Radiation dose is in steady decline" has been confirmed. On August 17, we 
updated the further progress. 
By bringing the reactors and spent fuel pools to a stable cooling 
condition and mitigating the release of radioactive materials, we will 
make every effort to enable evacuees to return to their homes and for all 
citizens to be able to secure a sound life.

Below is the status of TEPCO's major facilities.

*New items are underlined

[Nuclear Power Station]
Fukushima Daiichi Nuclear Power Station:
   Units 1 to 3: shutdown due to the earthquake
   (Units 4 to 6: outage due to regular inspections) 

-At 3:30 pm on August 19, as we confirmed the decrease in the rate of
 water injection to the reactor of Unit 2, we adjusted it at approx.
 3.8 ㎥/h.
-At 2 pm on August 19, we stopped the operation of the water treatment 
 system in order to switch to parallel operation of process line from 
 cesium adsorption instruments to decontamination instruments, and another 
 process line of second cesium adsorption instruments.
-At 3:44 pm on the same day, we started up the process line from cesium
 adsorption instruments to decontamination instruments. At 3:54 pm, it was
 confirmed that the rated flow was achieved and there were not any other
 problems to operation conditions. Afterward, at 7:33 pm on the same day,
 we started up the process line of second cesium adsorption instruments.
 At 7:41 pm, the rated flow was achieved and we started parallel operation.

Fukushima Daini Nuclear Power Station:
   Units 1 to 4: shutdown due to the earthquake

Kashiwazaki Kariwa Nuclear Power Station:
   Units 5, 6, 7: normal operation
   (Units 1 to 4: outage due to regular inspection)

[Thermal Power Station]
-Power supply has returned to normal and facilities damaged by the 
 earthquake are now being handled in a timely manner.

[Hydro Power Station]
-Power supply has returned to normal and facilities damaged by the 
 earthquake are now being handled in a timely manner.

[Impacts on Transmission Facilities]
-Power supply has returned to normal and facilities damaged by the 
 earthquake are now being handled in a timely manner.

[Perspective of Power Supply and Demand Balance in this Summer]
In regard to the supply side in this summer, taking in account of the 
acceleration of restoration schedule for Hirono Thermal Power Station, 
more purchase of privately generated power, and excluding the power supply 
from 60Hz areas which had been planned (due to the current difficult 
situation), supply capacity outlook is amended to 55.8GW at the end of 
August.

Also, in order to ensure the supply and demand balance in the Tohoku area 
that have sustained severe damages from the earthquake and torrential 
rains, we would like to supply maximum electricity to Tohoku Electric 
Power Company by thoroughly implementing both supply and demand 
countermeasures. 

Estimated peak demand of 55GW for this summer is 5GW lower than that of 
last year. This incorporates the saving of electricity from "Outline of 
Countermeasures for Power Supply and Demand During Summertime" and 
restoration from decrease of production due to the quake.

As the occurrence of unplanned outage of aged thermal power stations or 
sudden increase of demand due to unexpected high temperature during summer 
may cause difficulties in maintaining stable demand supply balance, in 
order to continue to avoid planned blackouts, we will steadily maintain 
supply capacity, and continue our efforts on reliable operation and 
maintenance of power facilities.

We apologize for the inconvenience this may cause and appreciate for your 
cooperation to save electricity.
