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 7:27 am on July 1,we stopped injecting treated water and implemented
  injecting filtered water to ( no change in amount ) due to construction
  of installment of the Tank (buffer tank) for injecting to the reactor. 
- At 6:00 pm on July 2, we started full scale operation of circulating
  injecting cooling which inject treated water by accumulated water
  treatment system to the reactor via buffer tank.
- At 6:55 on July 3, our employee found the leakage of seawater at one of
  outlet piping in 2 residual heat removal systems. Those 2 pumps will be
  stopped hereafter due to change defective piping.

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.
