Press Release (Jul 11,2011)
Status of TEPCO's Facilities and its services after the Tohoku-Chihou-Taiheiyou-Oki Earthquake (as of 9:00 AM, July 11)
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 4:53 am on July 10, we confirmed the leakage at the chemical injection 
  line of the coagulation settling equipment of the water treatment 
  facility, and stopped the operation of the facility. Water injection into 
  the reactor is continued. Afterward, we repaired the leakage point and at 
  5:06 pm on the same day, we started-up the facility. At 5:40 pm, water 
  treatment was restarted. Water injection into the reactor is continued.

- At 3:03 am on July 11, with the restoration work for 2 lines of Yonomori 
  line for the purpose of reliability improvement of site power, we started 
  operations for emergency diesel generator (A) and (B) of Unit 5 and 
  emergency diesel generator (A) and (B) of Unit 6 (offsite power source for 
  Unit 5 and 6 was stopped).

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.
