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 November 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.

* Underlined are updates from the previous press release.

[Nuclear Power Station] 

· Fukushima Daiichi Nuclear Power Station: Unit 1 to 3: shut down due to the 
  earthquake
  (Units 4 to 6: outage due to regular inspections)

* At 9:12 am on November 28, the alarm indicating that the difference of 
  flow rates between at the entering and at the exit of the primary pump 
  at the alternative cooling system for the spent fuel pool is big went 
  off, and the system automatically stopped. At 9:16 am on the same day we 
  checked the site and no abnormality such as no leakage was confirmed. We 
  are investigating the cause.

* Approx. at 2:28 pm on November 28, the alarm went off from an indicator 
  installed in front of Main Anti-Earthquake Building to continuously 
  measure airborne radiation dose (continuous dust monitor). In response 
  to the alarm, we instructed to put full face masks on at 2:38 pm 
  accordingly. We are measuring the airborne radiation dose in front of 
  Main Anti-Earthquake Building, and investigating the cause. 
  We confirmed that there are no significant changes in the readings of 
  the monitoring posts.

· 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]
This winter, there will be some minus factors such as the regular 
inspection of Unit 5 at Kashiwazaki-Kariwa Nuclear Power Station. On the 
other hand, there will be several plus factors such as the recovery of the 
common thermal power stations which suffered the earthquake. As a result, 
we expect to secure 54.9 GW (at the end of December), 54.6 GW (at the end 
of January), 53.7 GW (at the end of February) supply power. 
Compared to the maximum demand in the last winter, which is 51.5 GW, we 
will have 2.2 - 3.4 GW generation reserve margin.

We expect to maintain stable power supply this winter, however, as there 
remains possibilities of unplanned shutdowns at our power stations and 
growth in the demand according to the rapid change in the temperature, we 
would like to ask your reasonable effort to save electricity.

We will continue to make our efforts to maintain stable operation and 
maintenance of the power facilities in order to "prevent in principle" the 
planned blackouts and secure power supply.
