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 around 11:57 am on July 24, the water desalinations stopped with a 
  warning sign. We replaced the faulty equipment with a spare and started 
  it at 7:19 pm. We supplied water to the buffer tank from the filtrate 
  tank and continuing water injection into the reactors of Units 1 to 3.
- At 10:37 am on July 24, freshwater injection started into the reactor 
  well and facility storage pool of Unit 4. We finished freshwater injection 
  at 3:20 pm on July 24.
- At 11:00 am on July 24, we restarted transferring accumulated water from 
  the turbine building of Unit 6 to the temporary tank. We stopped 
  transferring at 4:00 pm on July 24.

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 57.3GW 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 55.9GW 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.
