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 9:00 am on June 30, we stopped the water desalination system to treat
 the concentrated saltwater in the storage tank of the system. At 3:52 pm
 on July 1, we have restarted the system.
-At 11:43 am on July 1, we started to clean up the first floor of Unit 3
 Reactor Building using a robot. At 4:36 pm on the same day, we finished
 the cleaning.  

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.
