Due to the Tohoku-Chihou-Taiheiyou-Oki Earthquake which occurred on March
11th 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 17th, we have put together the roadmap towards restoration from
the accident. 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) 

-Since May 2nd, we have been working to install the ambient air filtration
 system to improve the work environment in the reactor building of Unit 1.
-At 2:00 pm on May 3rd, we resumed transfer of water accumulated in the  
 basement of turbine building of Unit 6 to a temporary tank. 
-On May 3rd, an unmanned crawler dump truck sprayed dust inhibitor to  
 prevent radioactive materials on the ground from flying to approximately  
 4,000 m2 areas in the west side of the reactor building of Unit 3. On May  
 3rd, we also sprayed dust inhibitor to approximately 5,300 m2 areas in  
 the slope surrounding the former Administration Office building by  
 conventional method.

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 Units 2 and 4: Shutdown due to the
 earthquake
-Hitachinaka Thermal Power Station Unit 1: 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.

[Avoidance of further Implementation on Planned Rolling Blackouts and
Request for Conserving Electricity Consumption] 
Currently, we are working to restore electricity supply after our nuclear
and thermal power facilities were severely damaged by
Tohoku-Chihou-Taiheiyou-Oki Earthquake. The widespread understanding and
cooperation of our customers to conserve electricity have contributed to
the improvement of this tight power supply-demand balance situation.
Amidst this backdrop, since the electricity supply will be able to balance
with the demand for the time being, we have decided not to implement
further rolling blackouts in principle.
However, we sincerely ask for your continued cooperation in reducing
electricity consumption due to the possible increase in demand caused by
warmer weather or unexpected trouble at power stations that are currently
being restored to service. In case the electricity supply-demand balance
becomes tighter than expected, we may regrettably need to restart the
implementation of rolling blackouts, with prior notice. We kindly ask for
your cooperation.
We will do our best to maintain this policy of avoiding further
implementation of rolling blackouts during the summer.
