Press Release (Jul 02,2011)
Status of TEPCO's Facilities and its services after the Tohoku-Chihou-Taiheiyou-Oki Earthquake (as of 3:00 PM, July 2)
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 10:59 am on July 2, we started measuring radiation dose at the first
 floor of Unit 3 Reactor Building using a robot. At 12:14 pm on the same
 day, we finished measuring radiation dose.
-At 10:30 am on July 2, we stopped operation of water treatment system
 for flushing system etc. at 1:45 pm on the same day, we restarted water
 treatment system.

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.
