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) 

 * Around 1:40 pm on January 14, extremely small amount of water leakage 
   was found from 2 pinholes of the hose in water transfer line between 
   the vertical shaft in Unit 1 to the centralized radiation waste 
   treatment facility while water passing test was being conducted. The 
   leakage stopped after suspending the pump. The result of sampling 
   indicated Iodine 131 was below measurable limit, Cesium 134 was 
   1.8x101Bq/cm3 and Cesium 137 was 2.0x101Bq/cm3, We estimate that it 
   is mixture of sea water and rain water. The pinholes were closed by 
   plastic.  
   The water leakage point is the outdoor laying part at flushing line 
   that transfer the accumulated water of the vertical shaft in Unit 1 to 
   the accumulated water transfer line in Unit 2. The amount of water 
   leakage is estimated to be less than approximately 1 liter. 

· 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.
