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.

* The underlined parts are the 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 1:58 pm on November 20, as it was confirmed that there was a 
    decrease in the water injection amount from the feed water system at 
    unit 1 reactor, injection amount was adjusted from 5.3m3/h to 5.5m3/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]
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.
