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 roadmap considering the current situation, 
on June 17. 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 8:13 am on June 4, an alarm showing decrease in amount of water 
 injection was confirmed at unit 1 reactor. We adjusted injection rate 
 from approximately 3.0m3 to approximately 7.5m3 with flushing. At 8:50 am 
 on the same day, we adjusted injection rate to approximately 3.8m3. We 
 are currently following up the details.
-At 8:17 am on June 3, we stopped transferring contaminated water due to 
 the buffer tank capacity. Water injection to the reactor and water 
 treatment of accumulated water are ongoing.
-On June 3, we laid steel sheet near the carry in entrance of unit 3 
 reactor building to decrease the exposure dose.
-From 10:00 am on July 1 to 4:00 pm on July 3, we transferred accumulated 
 water from inside of turbine building of Unit 6 to temporary tank. 
-From 10:00 am on July 1, we transferred low radioactive stored water from 
 outdoor temporary tank to Mega Float. At 4:00 pm on June 3, the transfer 
 was paused due to pipe arrangement change.

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]
-Hirono Thermal Power Station Unit 2 and 4: Shutdown due to the earthquake

[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 with 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 56.8GW at the end of 
July, and 55.6GW at the end of August.
Also, in order to support balance of demand and supply 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 55.4GW at the end of July, and 54.2GW 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.
