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, we have compiled the roadmap towards restoration from the
accident and then we updated the progress status of roadmap considering
the current situation, on July 19. Accomplishment of the Step1 target
"Radiation dose is in steady decline" has been confirmed. On October 17,
we updated the further progress. 
By bringing the reactors and spent fuel pools to a stable cooling
condition and mitigating the release of radioactive materials, we will make
every effort to enable evacuees to return to their homes and for all
citizens to be able to secure a sound life.

Below is the status of TEPCO's major facilities.

*The underlined parts are the updates from the previous press release.

[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 9:38 am on November 4, we started transferring accumulated water from
 the basement of the Unit 2 turbine building to Centralized Radiation
 Waste Treatment Facility (Miscellaneous Solid Waste Volume Reduction
 Treatment Building [High Temperature Incinerator Building]).

*At 10:00 am on November 4, we started transferring accumulated water
 from On-site Bunker Building to Centralized Radiation Waste Treatment
 Facility.

*From 1:35 pm to 2:35 pm on November 4, we conducted dust sampling at the
 opening for the equipment hatch in the reactor building and truck bay
 door of Unit 1.

*At 2:20 pm on November 4, we arranged the amount of emission from the
 gas management system from 14m3/h to 22 m3/h in order to balance the
 amount of nitrogen injected to the reactor containment vessel and
 exhaust gas from the gas management system of Unit 2.

·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-Kriwa 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 million kW (at the end of December), 54.6 million
kW (at the end of January), 53.7 million kW (at the end of February)
supply power. 
Compared to the maximum demand in the last winter, which is 51.5 million
kW, we will have 2.2 ? 3.4 million kW 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.
