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.

* Updates are underlined. 

[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 7:15 pm on January 24, regarding the water injection of Unit 2, we 
  adjusted the water injection amount from core spray system from approx 
  0.6 m3/h to approx 1.0 m3/h since we confirmed change of water injection 
  amount.  
  (We maintain the water injection amount from water injection system at 8 
  m3/h) 
- At 3:24 pm on January 24, we started transferring the accumulated water 
  from the basement of the turbine building of Unit 3 to the centralized 
  radiation waste treatment facility (miscellaneous solid waste volume 
  reduction treatment building [high temperature incinerator building] and 
  process main building). At 8:57 am on January 25, we stopped transferring. 
- At 3:36 pm on January 24, we started transferring the accumulated water 
  from the basement of the turbine building of Unit 2 to the centralized 
  radiation waste treatment facility (miscellaneous solid waste volume 
  reduction treatment building [high temperature incinerator building] and 
  process main building). At 8:53 am on January 25, we stopped transferring. 
- Because of the finding of accumulated water included radioactive 
  materials at the trench between the process main building and the 
  miscellaneous solid waste volume reduction treatment building [high 
  temperature incinerator building](December 18, 2011), we started the 
  inspection of other trenches at the site on January 11.
  As a result of the inspection of January 24, the locations where 
  accumulated water was discovered and the nuclide analysis results 
  (quick estimation) are as follows:   
   · Inside of Connection trench between boiler room and electric equipment 
     room of Unit 1 
     I-131:below measurable limit, Cs-134:approx. 7.9x10-1Bq/cm3, 
     Cs-137:approx. 1.0x100Bq/cm3 
   · We confirmed no puddle in Unit 3-4 heavy oil pipe trench. 
   · Inside of Unit 4 main transformer cable duct 
     I-131:below measurable limit, Cs-134:approx. 7.5x10-1Bq/cm3, 
     Cs-137:approx. 1.0x100Bq/cm3 

· 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) 

   * The 13th regular inspection of Unit 5 started on January 25. 

[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).
