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 10:46 am on June 30, we stopped the Accumulated Water Treatment
  Facility, for flushing the system. At 1:35 pm on the same day, we
  restarted the Facility. At 2:36 pm, we re-stopped the Instruments due to
  the defect of Coagulation Setting Facility. Now, we are investigating
  the detail. After adjustment of water level set value of Coagulation
  Setting Facility treated water tank, at 6:50 pm on the same day, we
  resumed operation.
- At 7:27 am on July 1, we stopped injecting treated water and started
  injecting only filtrate water, for the installation of the tank for
  injection to the reactor (buffer tank) (no change of injection rate).
- At 1:00 pm on June 30, we started transferring of low radioactive stored
  water from temporary tank to Mega Float. At 7:00 pm on the same day,
  transfer was completed.
- At 3:00 pm on June 30, we started transferring of accumulated water from
  inside of turbine building of Unit 6 to temporary tank. At 7:00 pm on
  the same day, transfer was completed.
- At 7:47 pm on June 30, we started the Alternative Cooling System of
  spent fuel pool of Unit 3. It is currently under control operation.
  After performance evaluation, we plan to bring to a full operation.
- At 5:00 pm on June 30, the installation of temporary storm surge barrier
  was completed.

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.
