Due to the Tohoku-Chihou-Taiheiyou-Oki Earthquake which occurred on March 
11, 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 17, we have compiled the roadmap towards restoration from the 
accident and then we updated the roadmap considering the current situation, 
on May 17. 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 8:00 am on May 31, we confirmed oil leakage to the sea surface 
 around the curtain wall of the water intake canal of Unit 5 & 6 and 
 reported the issue to Futaba Wide-area Fire Headquarters and Fukushima 
 Coastguard Office. As a result of our investigation, we confirmed that 
 oil leaked from pipes around seawall to the port through holes of steel 
 sheet piles and that the leakage already stopped. Since the diffused 
 area was just around the curtain wall and the surface of the sea around 
 Shallow Draft Quay and the oil film was very thin, we confirmed that 
 there is no spread to the outer sea. We completed installing 
 oil-absorbing mat around seawall at 2:00 pm and also completed 
 installing oil fences at 4:50 pm. At 10:00 am on June 14, we closed the 
 open part at the bottom of curtain wall, through which the oil leaked.  
·At 3:35 pm on June 14, water injection was temporarily suspended due to 
 the switch of injection pipeline to Unit 1 reactor. Water injection was 
 resumed at 3:50 pm.
·At 12:14 pm on June 14, water injection was temporarily suspended due to 
 the switch of injection pipeline to Unit 2 reactor. Water injection was 
 resumed at 12:37 pm.
·At 1:02 pm on June 14, water injection was temporarily suspended due to 
 the switch of injection pipeline to Unit 3 reactor. Water injection was 
 resumed at 1:31 pm.
·From 4:10 pm to 8:52 pm on June 14, we injected freshwater to Unit 4 
 spent fuel pool by concrete pumping vehicle (From 4:11 pm to 7:15 pm, 
 hydrazine [corrosion inhibitor] was also injected at the same time).  
·From 10:00 am to 4:00 pm on June 14, we transferred accumulated water at 
 the basement of the turbine building of Unit 6 to the temporary tank. 
·On June 14, we sprayed dust inhibitor to areas including areas 
 surrounding Unit 5 and 6 extra high voltage switching station. (approx. 
 8,750㎡)   
 
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)

It is expected that we will be able to maintain the policy of avoiding 
further implementation of rolling blackouts this June because it is 
estimated that we will be able to secure the capacity exceeding the 
maximum forecasted demand as of now, thanks to your understanding as well 
as cooperation on saving electricity.

However 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. We apologize for the inconvenience this may cause and appreciate 
for your cooperation to save electricity.
