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 since the previous press release 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 2:39 pm on January 11, to protect the decline of facilities which are 
   needed to maintain the stable cold shutdown and improve the 
   high-humidity environment in the Reactor Building of Unit 5, we started 
   up ventilation and air-conditioning system in the building. At 4:20 pm 
   on January 11, we activated the air ventilation/conditioning system of 
   the Unit 6 turbine building. The air out of the conditioning system has 
   been emitted through high-performance particle filter installed at the 
   intake and exhaust side. On January 13, we conducted the nuclide 
   analysis on the samples collected at exhaust stack of Unit 5 and 6. As 
   a result, no radioactive materials were detected. 

 * At 2:46 pm on January 13, we started transferring accumulated water from 
   the basement floor 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 
   the Process Main Building). At 8: 07 am on January 14, we stopped the 
   transfer.

 * At 2:54 pm on January 13, we started transferring accumulated water from 
   the basement floor 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 
   the Process Main Building). At 8: 11 am on January 14, we stopped the 
   transfer. 
· 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. 
  In the inspection conducted on January 13 we confirmed puddle water and 
  the results of nuclide analysis as shown below.
   · Unit 1 radioactive fluid piping duct  
     I-131: below measurable limit, Cs-134: 1.4×100Bq/cm3 ,Cs-137: 1.9× 
     100Bq/cm3 
   · Unit 4 radioactive fluid piping duct 
     I-131: below measurable limit, Cs-134: 2.2×101Bq/cm3 ,Cs-137: 2.8× 
     101Bq/cm3 

· 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 54.6 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.
