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 4:20 pm on June 27, we started to use treated water by water treatment
  system for injecting to the reactors of Unit 1, 2 and 3. At 5:55 pm, we 
  confirmed a leakage from the pipe which supplies water from treated water
  tank to injection pumps of the reactors and we stopped supplying the 
  treated water. We replaced the pipe with a new one and started to operate 
  the transfer pumps of water treatment system at 2:36 pm, June 28. After 
  confirming no leakage and adjusting water volume, we started to operate 
  circulating injection cooling at 3:55 pm, June 28. 

- On June 28, we started construction work of installing covers over the 
  reactor buildings by moving crawler cranes. 

- At 8:06 pm on June 28, we started to inject nitrogen gas into the Primary 
  Containment Vessel of Unit 2. 

- At 9:40 am on June 28, we started injecting fresh water to reactor dry
  well and dry separator pit and finished at 3:29 pm on June 28. 

- From 11 am to 1:20 pm, June 28, we transferred accumulated water on the 
  basement of Unit 6 Reactor Building to the accessory building of the 
  reactor building (Radioactive Waste Treatment Building). 

- On June 28, dust inhibitor was sprayed on the area of approx. 541 m2 
  around filtrate water tank.

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 planned 
blackouts, we will steadily implement installation of additional power 
capacity as we have planned, 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.
