Press Release (Jan 18,2012)
Status of TEPCO's Facilities and its services after the Tohoku-Chihou-Taiheiyou-Oki Earthquake (as of 4:00 pm, January 18)
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 3:00 pm on January 18, 2012, the instrument to measure the 
   concentration of radioactive materials in air continuously (continuous 
   dust monitor), which is located in front of Main Anti-Earthquake 
   Building, issue an alert. Following the alert, based on the operation 
   rule of full-face mask wearing, we instructed to wear the full-face 
   masks from 3:11 pm on the same day. 
   Later, we confirmed that there was no valid fluctuation on the value 
   shown by the monitoring post. We replaced the filters of the 
   measurement instrument, and rebooted the instrument by resetting at 
   3:40 pm on the same day. According to the result of manual measurement 
   of radioactive materials in air in front of Main Anti-Earthquake 
   Building, the concentration of radioactive materials in air at Main 
   Anti-Earthquake Building was less than the detection level (the 
   detection limit: 1.4 x 10-5[Bq/cm3] and the value was less than the 
   standard level to wear full-face masks (1 x 10-4[Bq/cm3]. Therefore, we 
   announced to resume the normal operation which does not require to wear 
   full-face masks.
·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.
