Press Release (May 06,2011)
Status of TEPCO's Facilities and its services after the Tohoku-Chihou-Taiheiyou-Oki Earthquake(as of 9:00AM, May 6)

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.
*Updates from previous press release 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 4:36pm on May 5th, we started to ventilate with 6 local exhausters  
 the reactor building of Unit 1 in order to improve the working 
 environment of the building. 
-From 12:19pm to 8:46pm on May 5th, we implemented water spray to the 
 spent fuel pool of Unit 4 by a concrete pumping vehicle.
 
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 Unit 2 and 4: Shutdown due to the earthquake
-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.
