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) 

- From 5:52 am on August 3, in order to replace the nitrogen gas injector 
  device, we stopped nitrogen gas injection into the Primary Containment 
  Vessel of Units 1 to 3. After completion of the replacement, we restarted 
  injection of nitrogen gas into Unit 1 at 8:33 am, into Unit 2 at 8:29 am, 
  into Unit 3 at 8:29. (Regarding Unit 2, we continued injection of 
  nitrogen gas with a backup injector from 5:58 am to 8:27 am.)
- At 4:10 pm on July 30, we started transfer of the accumulated water from 
  the vertical shaft of the Turbine Building of Unit 2 to Centralized 
  Radiation Waste Treatment Facility(Process Main Building). We stopped 
  transfer at 6:49 pm on August 2.
- At 5:05 pm on August 2, in order to fill water in the skimmer surge tank 
  of Unit 4. we started injection of fresh water using an alternate water 
  injection line. We stopped injection at 5:37 pm.
- At 10:00 am on August 2, we resumed transferring the accumulated low 
  concentrated water which was transferred from the turbine building of 
  Unit 6 to the temporary tank to Mega Float. We stopped transfer at 5:00 
  pm.
- At 11:00 am on August 2, we resumed transferring the accumulated water in 
  the basement in the turbine building of Unit 6 to the temporary tank. We 
  stopped transfer at 4:00 pm.

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

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.
