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 10:00 am on July 13, we resumed transferring low radioactive 
  accumulate water, which had been transferred from Unit 6 turbine building
  to temporary tanks, from temporary tanks to Mega Float. Transfer finished
  at 5:00 pm.
- Between 8:40 - 10:50 am, on July 13, transfer of accumulated water at
  Unit 6 reactor building basement to the accessory building for reactors
  (the radiation waste treatment building) was implemented.
- At 1:00 pm on 13th July, transportable monitoring post, which was 
  monitoring radiation dose at the main gate, recorded zero. We checked the
  monitoring equipment and restored by restarting power at 2:55 pm on the 
  day. At 10:00 pm, we found the same equipment showing zero. As the
  equipment did not restore by restarting, we are planning to either repair
  or replace the equipment.

Fukushima Daini Nuclear Power Station:
   Units 1 to 4: shutdown due to the earthquake

- At 4:05 July 13, regarding some monitoring post (No. 3) installed within
  the station site, we started cleaning such as wiping off the inside of
  the cover covering monitoring device and pole of the monitoring posts.
  Cleaning was finished at 5:00 pm.

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 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.
