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 10:00 am on June 20, we started transferring accumulated water in the 
  basement of the turbine building of Unit 6 to the temporary storage tanks. 
  The transfer was finished at 4:00pm. 
- At 12:45 am on June 21, we started a water flow test using highly 
  concentrated contaminated water in Cesium adsorption Instruments of the 
  water treatment facility. At 7:20 pm on the same day, a pump transferring 
  filtrated water to coagulation settling instrument tripped, and water 
  treatment facility stopped. 
- On June 20, we sprayed dust inhibitors to yards around Unit 5 in an area 
  of approx, 5,800m2, in order to inhibit scattering of radioactive 
  materials on the ground by a crawler dump truck. 
  On June 20, workers sprayed dust inhibitors to materials yards etc to an 
  area of approx. 5,250m2.

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 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.
