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.

*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 3:45 pm on September 15, with regard to the injection into the
  reactor of Unit 2, we adjusted the amount of water injection from the
  core spray system to approx. 2.0 m3/h (the amount from the feeding water
  system is kept at approx. 3.8 m3/h)

 *At 10 am on September 15, we restarted transfer of the accumulated water
  from the basement of the turbine building of Unit 6 to the temporary
  tank and at 4 pm on the day we stopped it.

 *We found that the density of radioactive materials is increasing after
  treatment by decontamination instruments when we check the performance
  of treatment of water treatment instruments (decontamination instrument
  and cesium adsorption instrument). In order to find out causes, at 6:22
  pm on September 15, we stopped operating the water treatment instruments
  and at 6:42 pm started to operate only the cesium adsorption instrument
  and it reached the rated flow (approx. 30 m3/h) at 6:46 pm. With regard
  to the second cesium adsorption instrument, it has been in operation.

- 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.
