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 June 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 approximately 7:00 am on June 24, an unmanned helicopter collecting 
  dust from the open part of the reactor building of Unit 2 made an 
  emergency landing on the top of the reactor building of Unit 2. 
  Thereafter, we confirmed no impact made to the reactor building of Unit 2 
  through the monitoring camera equipped onto the tip of a concrete pumping 
  vehicle. 

- At 10:00 am on June 24, we temporarily stopped the operation of water 
  treatment facilities and replaced Cesium Adsorption Tower. After starting 
  the operation of water desalination facilities for the first time 
  at 12:00 pm, we resumed the operation of water treatment facilities 
  at 12:50 pm. 

- At 10:07 am on June 24, we changed the water amount injected through 
  reactor feed water system piping arrangement from approx. 9.5m3/h to 
  approx. 9m3/h. 

- On June 24, dust inhibitor that prevents the spread of radioactive 
  materials has been sprayed on the north side of the turbine building of 
  Unit 6 by a crawler dump truck. Workers are also spraying dust inhibitor 
  at around Main Anti-Earthquake Building. 

Fukushima Daini Nuclear Power Station: 
       Units 1 to 4: shutdown due to the earthquake 
 
- At 2:45 pm on June 23rd, at check point of service building of Unit 1 and 
  Unit 2, a security agent, who attended materials taking out, caught his 
  clothing to the fire extinguisher on the wall and dropped to injure right 
  foot little finger. The security agent was transferred to the J-village 
  and arrived at 3:58 pm. After the diagnosis by a doctor, he was 
  transferred at 4:30 pm to Sogo Iwaki Kyoritsu Hospital by ambulance. 
  After the treatment, he went home. No contamination was found due to the 
  body survey.
  As a result of another diagnosis on June 24, he has been diagnosed as 
  laceration of the fifth finger on right foot, fracture of distal phalanx 
  and needs about 4 weeks for outpatient treatment. 

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 planned 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.
