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 4:47 pm on August 10, we started transferring accumulated water at
  Unit 2 turbine building to Centralized Radiation Waste Treatment
  Facility (Process Main Building), and stopped the transfer at 11:43 am
  on August 16.

- At 12:04 pm on August 16, we stopped the operation of the water
  treatment system and started the trial operation of the second cesium
  adsorption instruments.

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 56.1GW at the end of
August.
Also, in order to ensure the supply and demand balance in the Tohoku area
that have sustained severe damages from the earthquake and torrential
rains, we would like to supply maximum electricity to Tohoku Electric
Power Company by thoroughly implementing both supply and demand
countermeasures. 
 
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 planned 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.
