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. 
 
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 10:13 am on April 16th, water injection to the spent fuel pool of 
 Unit 2 was initiated using a temporary motor driven pump. It was finished 
 at 11:54 am. 
 
*From 11:00 am on April 16th, we conducted spraying dust inhibitor in  
 order to prevent diffusion of radioactive materials on the ground. This  
 attempt was conducted on trial basis at the mountain side area of the  
 common spent fuel pool in the range of approximately 1,800 m2.  
 
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 
  earthquake 
 -Hitachinaka Thermal Power Station Unit 1: Shutdown due to the earthquake 
 -Kashima Thermal Power Station Unit 6: 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 must 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, as stated, we may reluctantly restart the 
 implementation of rolling blackouts. 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.
