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. On August 17,
we updated the further progress.
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.

* New items 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 1:00 pm on August 20, we adjusted the rate of water injection into
  the reactor at approx. 7.0 m3/h.
- As we confirmed that there was no problem with the desalting facility
  for the spent fuel pool of Unit 4 through a trial operation at 10:24 am
  on August 20, at 11:34 on the same day we started to operate it fully.

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

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 55.8GW at the
end of August.

Also, in order to ensure the supply and demand balance in the Tohoku area
that have sustained severe damages from the earthquake and torrential
rains, we would like to supply maximum electricity to Tohoku Electric
Power Company by thoroughly implementing both supply and demand
countermeasures. 
 
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 planned 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.
