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) 

* From 1:40pm to 2:00pm on April 22nd, we injected fresh water to the 
  spent fuel pool of Unit 3 from the fuel pool cooling and filtering 
  system on a trial basis. 

* From 2:19pm to 3:40pm, April 22nd, water was sprayed to the spent fuel 
  pool of Unit 3 by the concrete pumping vehicle. 

* From 5:14pm to 9:20pm, April 21st, water was sprayed to the spent fuel 
  pool of Unit 4 by the concrete pumping vehicle. 
  Note  On a material released at 11:00am on April 22nd, the time when 
  water was started to sprayed was stated as "7:14pm", but that was a 
  typing error and we meant "5:14pm."  We apologize for the error and 
  revised it.
 
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: resumed generating electricity at 
  4:10 am on April 20th
 
[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, 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.
