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 progress status of roadmap considering
the current situation, on July 19. Accomplishment of the Step1 target
"Radiation dose is in steady decline" has been confirmed.
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 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 7:19 am on August 7, as we observed increase of water injection to
  reactor on unit 3, we adjusted water injection rate to approx. 9.0m3/h.
- Low level accumulated water had been transferred from Unit 6 turbine
  building to temporary tanks. At 10 pm on August 6, we restarted
  transferring the accumulated water from temporary tanks to mega-float,
  and stopped at 5 pm on the same day.
- At 11 am on August 6, we restarted transferring the accumulated water
  on the basement of Unit 6 turbine building to temporary tanks, and
  stopped at 4 pm on the same date.
- At 8:07 am on August 7, water treatment facility has stopped as
  decontamination instrument has automatically stopped due to the trip of
  chemical injection pump of high speed coagulant facility. Water
  injection to the reactor of unit 1 to 3 has been continuing.

Fukushima Daini Nuclear Power Station:
       Units 1 to 4: shutdown due to the earthquake

- From 2:22 pm on August 6, we started commissioning of Residual Heat
  Removal (RHR) system (A) of Unit 2, which had been stopped due to
  tsunami. At 3:02 pm on the same day, commissioning has completed and
  transited to stand by mode.

Kashiwazaki Kariwa Nuclear Power Station:
       Units 5, 6, 7: normal operation
       (Units 1 to 4: outage due to regular inspection)

[Thermal Power Station]
- Power supply has returned to normal and facilities damaged by the
  earthquake are now being handled in a timely manner.

[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]
In regard to the supply side in this summer, taking in account of the
acceleration of restoration schedule for Hirono Thermal Power Station,
more purchase of privately generated power, and excluding the power
supply from 60Hz areas which had been planned (due to the current
difficult situation), supply capacity outlook is amended to 57.2GW at the
end of July, and 56.1GW at the end of August.
Also, in order to support the supply and demand balance in the Tohoku
area, which suffered severe damage from the quake, we would like to
supply maximum of 1.4GW to Tohoku Electric Power Company by thoroughly
implementing both supply and demand countermeasures. The supply capacity
in this regard will be 55.8GW at the end of July, and 54.7GW at the end
of August.
 
Estimated peak demand of 55GW for this summer is 5GW lower than that of
last year. This incorporates the saving of electricity from "Outline of
Countermeasures for Power Supply and Demand During Summertime" and
restoration from decrease of production due to the quake.

As the occurrence of unplanned outage of aged thermal power stations or
sudden increase of demand due to unexpected high temperature during
summer may cause difficulties in maintaining stable demand supply balance,
in order to continue to avoid rolling blackouts, we will steadily
maintain supply capacity, and continue our efforts on reliable operation
and maintenance of power facilities.

We apologize for the inconvenience this may cause and appreciate for
your cooperation to save electricity.
