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 10:08 am on July 31, we started alternative cooling system for spent
 fuel pool of Unit 4, and implemented trial run. At 0:44 pm on the same
 day, we conducted its performance assessment, and started the full-scale
 operation.
-At 10:00 am on July 31, we started transferring low-radiation level
 accumulated water, which we transferred from Unit 6 turbine building to
 temporary tank, from the temporary tank to Mega Float.
-At 11:00 am on July 31, we started transferring accumulated water from
 Unit 6 turbine building to temporary tank again.
-At approximately 10:50 am on July 31, we found the leakage between water
 desalination facility and primary storage tank of concentrated water of
 water desalination equipment along the transfer line. At 11:15 am on the
 same day, we stopped the transferring pumps. At 11:20 am on the same day,
 we stopped the water desalination facilities. After that, we closed the
 valves of the transfer line, confirming that the leakage stopped at 0:30
 pm on the same day. After replacing the line material and checking the
 status of leakage, we will start the water desalination facility again.
-At 1:58 pm on July 31, at Centralized Radiation Waste Treatment Facility,
 we started transferring accumulated water at Miscellaneous Solid Waste
 Volume Reduction Treatment Building (High Temperature Incinerator
 Building) to Process Main Building.

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.
