Press Release (Jul 29,2011)
Status of TEPCO's Facilities and its services after the Tohoku-Chihou-Taiheiyou-Oki Earthquake (as of 3:00 PM, July 29)
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.
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.
*Updates are underlined.

[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 4:56 pm on July 22, we started transfer of accumulated water from the 
  vertical shaft, T/B, Unit 2 to Centralized Radiation Waste Treatment 
  Facility (Process Main Building). At 9:43 m on July 29, we stopped the
  transfer.
- At 4:53 am on July 22, we started transfer of accumulated water from the 
  basement of Unit 3 T/B to Centralized Radiation Waste Treatment Facility 
  (Process Main Building). At 9:48 1m on July 21, we stopped the transfer.
- At 10 am on July 29, we commenced the accumulated water transferred from
  the basement of Unit 6 Turbine Building to the temporary tank.
- At 10:03 am on July 29, we commenced the accumulated water transferred
  from Miscellaneous Solid Waste Volume Reduction Treatment Building (High
  Temperature Incinerator Building) to Centralized Radiation Waste
  Treatment Facility (Process Main Building).
- From 10:37 am to 12:50 pm on July 29, we implemented the gas sampling of
  Unit 1 Primary Containment Vessel.
- At 11:55 am on July 29, we injected hydrazine into Unit 3 Spent Fuel Pool
  by using circulation cooling system. At 1:29 pm on the same day, we
  stopped the injection.

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

- From July 29, we are conducting major overhauls of 6 Monitoring Posts 
  located (No. 1 to 6) at the boundary of power station's premise out of 7 
  Monitoring Posts.
  (major inspection report)
- MP No. 6: major inspection from 9:31 am on July 29.

Kashiwazaki Kariwa Nuclear Power Station:
   Units 1, 5, 6, 7: normal operation
   (Units 2 to 4: 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 regard to the supply side in this summer, taking in account of the 
acceleration of restoration schedule for Hirono Thermal Power Station, more
purchase of privately generated power, and excluding the power supply from 
60Hz areas which had been planned (due to the current difficult situation),
supply capacity outlook is amended to 57.2GW at the end of July, and 56.1GW
at the end of August.
Also, in order to support the supply and demand balance in the Tohoku area,
which suffered severe damage from the quake, we would like to supply 
maximum of 1.4GW to Tohoku Electric Power Company by thoroughly 
implementing both supply and demand countermeasures. The supply capacity in
this regard will be 55.8GW at the end of July, and 54.7GW at the end of 
August.

Estimated peak demand of 55GW for this summer is 5GW lower than that of 
last year. This incorporates the saving of electricity from "Outline of 
Countermeasures for Power Supply and Demand During Summertime" and 
restoration from decrease of production due to the quake.

As the occurrence of unplanned outage of aged thermal power stations or 
sudden increase of demand due to unexpected high temperature during summer 
may cause difficulties in maintaining stable demand supply balance, in 
order to continue to avoid rolling blackouts, we will steadily maintain 
supply capacity, and continue our efforts on reliable operation and 
maintenance of power facilities.

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