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, 2011, we have compiled the roadmap towards restoration from the 
accident and on July 19 we accomplished the Step1 target "Radiation dose 
is in steady decline". Then on December 16 we confirmed the accomplishment 
of the Step 2 target "Release of radioactive materials is under control 
and radiation doses are being significantly held down".
In addition, on December 21, 2011, we have compiled the "Mid-to-long-Term 
Roadmap toward the Decommissioning of Fukushima Daiichi Nuclear Power Units 
1-4, TEPCO".
In addition to the maintenance of the plant's stable condition, we will 
implement Mid-to-Long Term countermeasures towards the decommissioning of 
Fukushima Daiichi Nuclear Power Units 1-4 to enable evacuees to return to 
their homes as soon as possible and reduce the anxiety of the people in 
Fukushima and the whole nation as soon as possible.

Below is the status of TEPCO's major facilities.

* The updates are underlined.   

[Nuclear Power Station] 

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

  - At 9:45 pm on January 29, we started transferring accumulated water  
    from the basement of Unit 2 turbine building to Centralized Radiation 
    Waste Treatment Facility (Miscellaneous Solid Waste Volume Reduction 
    Treatment Building [High Temperature Incinerator Building] and Process 
    Main Building), and at 8:19 am on January 30, we stopped the 
    transferring. 
  - At 9:50 pm on January 29, we started transferring accumulated water 
    from the basement of Unit 3 turbine building to Centralized Radiation 
    Waste Treatment Facility (Miscellaneous Solid Waste Volume Reduction 
    Treatment Building [High Temperature Incinerator Building] and Process 
    Main Building), and at 8:23 am on January 30, we stopped the 
    transferring. 
  - On January 29, we conduct a patrol under the series of water leakage 
    which seems to be occurred by the freeze. At 10:55 pm on the same day, 
    a freeze of Filtrate water was found around the header valve of the 
    circulating cooling equipment for the spent fuel pool. We have been 
    conducting water passing in order to prevent freezing around the area. 
    Also we established a floodlight and warmed the area to protect the 
    facility, we confirmed water passing trough the area in the morning  
    patrol which was started at 6:25 am on January 30. 

    · The water leakage newly found from the previous release (as of 6:00  
      pm on January 29)was as follows; 

    ○The exit line flange of seal water cooler of evaporative distillation  
      apparatus 3B (found at approx. 6:20 pm on January 29) 
      (Filtrate water*: Approx. 30L) 
    ○Minimum circulation pipe flange of water injection pump (A) located  
      upland (found at approx. 9:03 am on January 30) 
      (Filtrate water*: Approx. one drop in 7-8 seconds)  

    *Filtrate water: water taken from the barrage 

· Fukushima Daini Nuclear Power Station:
    (Units 1 to 4: shutdown due to the earthquake)

· Kashiwazaki Kariwa Nuclear Power Station: Units 6: under normal operation
    (Units 1 to 5 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 are some minus factors such as the regular inspection 
of Unit 5 at Kashiwazaki-Kariwa Nuclear Power Station*. On the other hand, 
there are several plus factors such as the recovery of the common thermal 
power stations which suffered the earthquake. As a result, we expect to 
secure 54.6 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 - 3.1 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. 
 
* Correction of Description in [Impacts on Power Supply and Demand Balance]
We described,"there will be some minus factors such as the regular 
inspection of Unit 5 at Kashiwazaki-Kariwa Nuclear Power Station" in the 
previous press release. However, because Unit 5 of Kashiwazaki-Kariwa 
Nuclear Power Station has already conducted a regular inspection since 
January 25, we revise the previous sentence to "there are some minus 
factors such as the regular inspection of Unit 5 at Kashiwazaki-Kariwa 
Nuclear Power Station". We would like to apologize for the correction 
(February 8, 2012).
