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 9:11 am on September 16, with regard to the injection into the reactor
 of Unit 2, as we observed decrease of injection rate of water, we
 adjusted the amount of water injection through the core spray system to
 approx. 2.0m3/h.

*From 10:16 am to 2:15 pm on September 16, at increasing volume of water
 injecting into the reactor of Unit 3, we conducted injection of boric
 acid into the reactor. Thereafter, we increased injection rate of water
 through core spray system and at 3:05 pm adjusted at 8.0m3 (injection
 rate from feed water system remain at 4.0m3/h).

*At 10:54 am on September 16, we could not monitor flow rate and pressure
 due to the fault of control board of second cesium absorption tower
 within the water treatment facility, we manually stopped operation of the
 facility. Thereafter, we replaced the control board and at 2:50 pm on the
 same day, restart the facility and at 2:57 pm returned to normal flow
 rate.

*At 9:53 am on September 16, we started transfer of the accumulated water
 from the condenser of Unit 1 to underground of the turbine building of
 Unit 1. We stopped transfer at 2:35 pm.

*At 3:35 pm on September 16, with regard to the injection into the reactor
 of Unit 2, we adjusted the amount of water injection through the core
 spray system to approx. 3.0m3/h (injection through feed water system
 remain at 3.8m3/h).

*At 3:41 pm on September 16, with regard to the injection into the reactor
 of Unit 1, as we observed decrease of injection rate of water, we
 adjusted the amount of water injection through the core spray system to
 approx. 3.8m3/h.

-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.
