Press Release (Apr 25,2011)
Status of TEPCO's Facilities and its services after the Tohoku-Chihou-Taiheiyou-Oki Earthquake(as of 3:00PM, April 25)
Due to the Tohoku-Chihou-Taiheiyou-Oki Earthquake which occurred on March 
11th 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 17th, we have put together the roadmap towards restoration from the 
accident. 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 have been 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 10:12 am on April 25th, we started water injection to spent fuel pool 
 in Unit 2 by the temporary motor driven pump. The operation was completed 
 at 11:18 am. 
*Work to connect high voltage power panel of Unit 1/2 and Unit 5/6 is 
 continuously under way. Before this work, the power source of pumps to 
 inject water to reactors was switched to a temporary diesel generator a 
 at 10:57 am on April 25th. The pump to inject nitrogen in Unit 1 was 
 stopped from 2:10 pm on April 25th. The pump of the residual heat removal 
 system to cool the reactor and spent fuel pool in Unit 5 was stopped from 
 12:22 pm on April 25th. 
*From 10:30 am on April 25th, the dust inhibiter was sprayed to the total 
 area of 3,800 m2 around the mountain side of reactor building of Unit 5, 
 slope in front of administration building, and gymnasium building. The 
 operation was completed at 12:30 pm. 
Fukushima Daini Nuclear Power Station: 
      Units 1 to 4: shutdown due to the earthquake   
Kashiwazaki Kariwa Nuclear Power Station:  
      Units 1, 5, 6, 7: normal operation 
          (Units 2 to 4: outage due to regular inspection)  
[Thermal Power Station]  
-Hirono Thermal Power Station Units 2 and 4: Shutdown due to the 
-Hitachinaka Thermal Power Station Unit 1: Shutdown due to the earthquake  
[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.  
[Avoidance of further Implementation on Planned Rolling Blackouts and  
Request for Conserving Electricity Consumption] 
Currently, we are working to restore electricity supply after our nuclear 
and thermal power facilities were severely damaged by 
Tohoku-Chihou-Taiheiyou-Oki Earthquake. The widespread understanding and 
cooperation of our customers to conserve electricity have contributed to 
the improvement of this tight power supply-demand balance situation.
Amidst this backdrop, since the electricity supply will be able to balance 
with the demand for the time being, we have decided not to implement 
further rolling blackouts in principle.
However, we sincerely ask for your continued cooperation in reducing 
electricity consumption due to the possible increase in demand caused by 
warmer weather or unexpected trouble at power stations that are currently 
being restored to service. In case the electricity supply-demand balance 
becomes tighter than expected, we may regrettably need to restart the 
implementation of rolling blackouts, with prior notice. We kindly ask for 
your cooperation.
We will do our best to maintain this policy of avoiding further 
implementation of rolling blackouts during the summer.
