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 from previous press release 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 8:59 am on August 10, we started injecting fresh water to Spent Fuel
  Pool of Unit 1 using Fuel Pool Cooling and Filtering System. At 9:19 am
  on same day, we finished injecting water.
- From 10:06 am to 11:15 on August 10, we activated alternative Fuel Pool
  Cooling System of Unit1 and conducted conditioning operation. At 11:22
  am on the same day, we started full-scale operation.
- At 12:20 pm on August 10, we adjusted flow rate of injecting water to
  approx.3.8 m3/h due to increasing injected water of reactor of Unit 1
  and 2.
- At 10:06 am on August 10, we started transferring accumulated water
  from On-site Bunker Building to Centralized Radiation Waste Treatment
  Facility. At 2:19 pm on same day, we stopped transferring.
- Around 12:05 pm on August 10, one partner company worker who was mowing
  for curing of water treatment hose at west side of Centralized
  Radiation Waste Treatment Facility (outside) was injured by sickle.
  After the first aid at the sickbay in Fukushima Daiichi Nuclear Power
  Station, he was transferred to the J village by ambulance around 1:12
  pm. At 2:11pm he was transferred from J village to the Fukushima Rosai
  Hospital.

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

Kashiwazaki Kariwa Nuclear Power Station:
  Units 5, 6, 7: normal operation
  (Units 1 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.
