Press Release (Jun 01,2011)
Status of TEPCO's Facilities and its services after the Tohoku-Chihou-Taiheiyou-Oki Earthquake (as of 3:00 PM, June 1)
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 compiled the roadmap towards restoration from the 
accident and then we updated the roadmap considering the current 
situation, on May 17th. 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 10:10 am on June 1, we changed the rate of water injection to the 
 reactor of Unit 3 through reactor feed water system piping arrangement  
 from approx. 12.5 m 3/h to approx. 11.5 m 3/h. 
-At 2:34 pm on June 1, we started the water injection to the spent fuel 
 pool of Unit 3 by a temporary motor driven pump. 
-On June 1, we are spraying dust inhibitor to the roof and exterior wall 
 of reactor building of Unit 2 using a bending spray tower vehicle. 
 On June 1, we are spraying dust inhibitor including the area near the 
 Main Gate.
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
[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] 
We have worked to restore electricity supply after our nuclear and thermal 
power facilities were severely damaged by Tohoku-Chihou-Taiheiyou-Oki 
Earthquake. This time, we revised that the supply capacity in this summer 
would increase because we could plan to secure an additional capacity. 
However, in order to maintain the policy of avoiding further 
implementation of rolling blackouts during the summer, in addition to the 
above increase of the supply capacity, we sincerely ask for your continued 
cooperation in reducing electricity consumption. Now we are creating 
concrete measures considering "Outline of Countermeasures for Power Supply 
and Demand During Summertime" presented by the Electricity Supply-Demand 
Emergency Response Headquarters of the Japanese government. 
                                                    (Previously Announced)

In the event that an unplanned outage such as excessive continuous 
operation in old plants and a sudden increase of power demand due to 
unusual hot temperature occur, there is a possibility to affect a stable 
power supply. In order to maintain the policy of avoiding rolling 
blackouts, we steadily implement to install additional power capacity we 
have planed, and we continuously do our best efforts to secure supply 
capacity.
