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 August 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.

*Underlined are new items

[Nuclear Power Station]
- Fukushima Daiichi Nuclear Power Station:
         Units 1 to 3: shutdown due to the earthquake
         (Units 4 to 6: outage due to regular inspections) 

*At 9:31 am, August 30, we stopped transfer of accumulated water from the
 vertical shaft of turbine building of unit 2 to Centralized Radiation
 Waste Treatment Facility (Miscellaneous Solid Waste Volume Reduction
 Treatment Building [High Temperature Incinerator Building]) and started
 transfer of accumulated water to Centralized Radiation Waste Treatment
 Facility (Process Main Building) at 9:39 am.

*At 9:46 am, August 30, we stopped transfer of accumulated water from the
 basement of turbine building of unit 3 to Centralized Radiation Waste
 Treatment Facility (Process Main Building) and at 9:54 am, we started
 transfer of accumulated water to Centralized Radiation Waste Treatment
 Facility (Miscellaneous Solid Waste Volume Reduction Treatment Building
 [High Temperature Incinerator Building]).

*In order to modify the software, at 3:32 am on August 30, we stopped the
 evaporative concentration apparatus 2A. At 4:16 am, we stopped the
 evaporative concentration apparatus 2B. After that, at 7:09 am on the
 same day, we stopped the desalination facility (RO) 1A. At 7:16 am, we
 stopped the desalination facility (RO) 2. We started the desalination
 facility (RO) 1A at 12:28 pm, and the desalination facility (RO) 2 at
 12:42 pm on the same day.

- Fukushima Daini Nuclear Power Station:
         Units 1 to 4: shutdown due to the earthquake

*At 12:59 pm on August 30, while operating High Pressure Core Spray
 Component Cooling System*1 and High Pressure Core Spray Component Cooling
 Sea Water System*2 in order to adjust the water quality in High Pressure
 Core Spray Component Cooling System, the motor of High Pressure Core
 Spray Component Cooling Sea Water System Pump stopped. Later, we
 confirmed a defect in insulation resistance at the site. As Unit 2 is in
 cold shutdown and necessary functions of water injection are secured, it
 satisfies obligations under the safety provisions for security management.

 *1 High Pressure Core Spray Component Cooling System
    One of the emergency core cooling systems. In case the water level in
    the reactor decreases abnormally, the system operates to cool the
    facilities to inject water into the reactor.
 *2 High Pressure Core Spray Component Cooling Sea Water System
    A system to cool High Pressure Core Spray Component Cooling System by
    exchanging heat with sea water.

- Kashiwazaki Kariwa Nuclear Power Station:
         Units 5, 6: under normal operation
         (Units 1 to 4 and 7: outage due to regular inspection)

[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.

[Perspective of Power Supply and Demand Balance in this Summer]
- In August and September, we forecast the maximum supply will be 56.1 GW,
  and the peak demand 48.9 GW.

We apologize for the inconvenience this may cause and appreciate for your
cooperation to save electricity.
