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 progress status of roadmap considering the current 
situation, on July 19. Accomplishment of the Step1 target "Radiation dose 
is in steady decline" has been confirmed.
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 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 10:56 am on July 16, we started transfer of accumulated water from 
  the vertical shaft, T/B, Unit 2 to Centralized Radiation Waste Treatment 
  Facility (Process Main Building). At 4:04 pm on July 21, we stopped the 
  transfer.
- At 10:50 am on July 16, we started transfer of accumulated water from 
  the vertical shaft, T/B, Unit 3 to Centralized Radiation Waste Treatment 
  Facility (Process Main Building). At 3:59 pm on July 21, we stopped the 
  transfer.
- At 8:38 am on July 21, we stopped operation of the water treatment 
  facility, because the water level gauge, which is set at suppression 
  pool water surge-tank (B), was powered off due to the change of power 
  sources associated with double circuit installation for offsite power 
  at Unit 5 and 6. At 12:28 am on July 22, we started the operation of 
  the water treatment facility, resuming water processing at 12:40 am on 
  the same day.

- At 7:10 am on July 22, the circuit breaker for the bus which supplies 
  electricity to a part of power network in the power station opened the 
  circuit due to overload, resulting in the power off of the following 
  facilities: the alternative cooling facility for spent fuel pool at Unit 
  3, monitoring gauges in the reactor of Unit 3 & 4, water treatment 
  facilities, Main Anti-Earthquake Building, and the cooling facility of 
  common pool. For Main Anti-Earthquake Building, we restore its power 
  supply immediately using backup power generator. For reference, this 
  event did not affect the following operations: water injection and 
  nitrogen gas injection to reactor of each unit, and data of each 
  monitoring post. Currently investigation of the cause of the event as 
  well as power restoration work are underway.
- From 5:06 am to 6:02 am on July 22, dust sampling survey was implemented 
  for the upper part of Unit 2's reactor building, using unmanned helicopter.

- Around 10:06am on July 18, a worker of the partner company fell from the 
  height of about 3m during the connection work of the optical cable on 
  the distribution pole near the power station's gazebo and he was injured. 
  At 10:50 am, he was transported to J village by service car. We requested 
  the helicopter emergency medical service (called "Doctor Heli") at 11:06 
  am. He was transported from multi purpose sports ground in Hirono town to 
  the Iwaki Kyouritsu Hospital by the Doctor Heli at 12:22 pm. According to 
  the result of physical examination, he was diagnosed as "fracture of 
  distal end of right radius, of left radius head, and left ligamentum 
  collaterale ulnare."

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]
- Power supply has returned to normal and facilities damaged by the 
  earthquake are now being handled in a timely manner.

[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 to 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 57.3GW at the end of 
July, and 56.1GW at the end of August.
Also, in order to support the supply and demand balance 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 55.9GW at the end of July, and 54.7GW 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.
