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)

 *Since the suction of the primary circulating pump of the spent fuel pool
  substitute cooling system of Unit 3 was continuously low, at 11:46 am on
  January 5 2012, we stopped the pump and temporarily suspended the
  cooling of the spent fuel pool to replace the strainer at the entrance
  of this system. (Temperature at the time of suspension: 23.7°C)After 
  that, since we finished the replacing the strainer, at 4:27 pm on 
  January 7, we restarted the pump and the cooling of the spent fuel pool 
  and confirmed restoring the suction of the pump.  (Current Temperature: 
  27.5°C) 

 *At 9:30 am on January 5 2012, we started transferring accumulated water
  from the ground 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 9:27 am on 
  January 8, we stopped the transferring. 

  At 10:01 am on January 3, 2012, we started to transfer accumulated
  water from the basement of 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 9:31 am on January 8, we 
  stopped the transferring. 

 *At 10:00 am on January 8, 2012, we started to transfer accumulated water 
  from the basement of turbine building of Unit 6 to temporally tank. 

 ·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.
