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 September 20,
 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.

* Updates are underlined.

[Nuclear Power Station]
- On September 28, relating to the water seal work at the southern part
  of Unit 1 to 4 open water channel, we completed countermeasures against
  contaminated water outflow and diffusion by using steal sheet piles at
  the points.
- At 10:00 am on September 28, we resumed transferring accumulated water
  from Unit 6 turbine building basement to temporary tanks. At 4:00 pm on
  the same day, we stopped the transfer.
- At 10:20 am on September 29, we stopped the desalination instrument (RO
  type) (2) as water leakage from the flange connection of transferring
  horse of concentrated water side was confirmed. At 10:45 am on the same
  day, we confirmed stop of water leakage after stop of the instrument.
  At 11:40 am on the same day, we restarted the instrument by using
  another system different from the one that leaked of the 2 systems of
  process lines.
- At around 10:30 am on September 29, the worker of the partner company
  got water from the drain hose to his full-face mask, when conducting
  the transfer of the concentrated waste water at the Water Treatment
  Facility.  Since it is confirmed that the part around mouth of the
  worker was contaminated, we conducted measurement by whole body counter.
  As the result of the measurement, we have confirmed that the worker did
  not take in any radioactive materials.

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

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

[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.

[Impacts on Power Supply and Demand Balance]
Thanks to our all customer's energy-saving efforts, we could
successfully maintain an even supply-demand balance in this summer. We
express our deepest appreciation to the efforts.

While we will continue to exert maximum effort to stabilize the supply-
demand balance, we kindly request your continued efforts in keeping
electricity consumption within reasonable levels.
