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 11:05 am on June 15, it was confirmed that a worker from a partner 
  company in charge of crane assembling work for the preparing for the 
  installation of the cover for Unit 1 reactor building at the shallow 
  draft quay was smoking with his full mask off. Later it was confirmed 
  the density of radioactive materials in the air at the working place 
  was below the detectable level both for particulate materials and iodine. 
  The evaluation exposure dose is external exposure---0.13mSv and internal 
  exposure---0.24mSv.  
· From 10:00 am to 4:00 pm on June 15, transfer of accumulated water in 
  the Unit 6 turbine building underground to the temporary tank was 
  implemented.
· From 1:10 pm to 8:35 pm on June 15, test operation of decontamination 
  instruments in the water treatment facilities was implemented with the 
  low level contaminated water.
· From 10:40 pm on June 15th to 12:20 am on June 16th, cesium adsorption 
  instruments and decontamination instruments of water treatment 
  facilities were operated with low-level contaminated water by trial.  
· At 12:20 am on June 16th, continuous operation of the whole water 
  treatment facilities with low level contaminated water was initiated  
· From 6:39 pm on June 4th to 8:40 am on June 16th, we transferred the 
  accumulated water in the vertical shaft in the turbine building of 
  Unit 2 to the centralized radiation waste treatment facility (process 
  main building).  
· From 10:05 am on June 14th to 8:46 am on June 16th, we transferred the 
  accumulated water in the basement in the turbine building of Unit 3 to 
  the centralized radiation waste treatment facility (process main 
  building).  
· On June 15, around super high voltage switching stations of Unit 5 and 
  6, we implemented spraying dust inhibitor (7,000㎡).  
 
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.
