Press Release (Jun 22,2011)
Status of TEPCO's Facilities and its services after the Tohoku-Chihou-Taiheiyou-Oki Earthquake (as of 9:00 AM, June 22)
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 1:37 pm on June 20, concerning the accumulated water in the trench of 
  Unit2 turbine building, we started to transfer to condenser in Unit1 
  turbine building. At 5:09 pm on June 21, we stopped to transfer. 
- At 10:00 am on June 21, we started transferring accumulated water in the 
  basement of the turbine building of Unit 6 to the temporary storage 
  tanks. We stopped to transfer at 4:00 pm on same day. 
- At 11:05 am on June 21, we started to transfer accumulated water in the 
  basement of reactor building of Unit 6 to reactor attached building 
  (waste treatment building). At 1:30 pm on the same day completed to 
  transfer. 
- At 11:55 am on June 21, we temporarily stopped operating the nitrogen 
  supply equipment to Unit 1 Primary Containment Vessel due to work to 
  install a transformer in the Power Station. At 6:03 pm we recommenced 
  operation of nitrogen supplying equipment. 
- At 3:32 pm on June 21, we started transferring accumulated water in 
  turbine building of Unit3 to central waste treatment facility building. 
- At 8:23 am on June 22, we started injecting fresh water to reactor well 
  and dry separator pit of Unit 4. 
- On June 21, we sprayed dust inhibitors to the area of approx.5,900m2 in 
  yards around Unit 5 in order to prevent scattering of radioactive 
  materials on the ground by a crawler dump truck. 
  On June 21, workers sprayed dust inhibitors to the area of approx. 
  5,250m2 in materials yards etc.
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.
