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 2:48 pm on January 15, 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 2:57 pm on January 15, 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). 

· 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.
