Press Release (May 05,2011)
Status of TEPCO's Facilities and its services after the Tohoku-Chihou-Taiheiyou-Oki Earthquake (as of 3:00PM, May 5)

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 approximately 12:19pm on May 5th, we started water spray to the spent 
 fuel pool of Unit 4 by a concrete pumping vehicle. 
-On May 5th, we sprayed the dust inhibitor at the west side of Unit 2 
 reactor building by an unmanned crawler dump truck, in order to prevent 
 diffusion of radioactive materials on the ground. On May 5th, we sprayed 
 the dust inhibitor at the mountain side of Shallow Draft Quay etc. by a 
 conventional method. 
-At around 11:00 am on May 5th, a worker fell from the stepladder and got 
 injured when assembling a temporary rest station at the parking area 
 outside the west gate of the power station. The worker was taken to the 
 Fukushima Rosai Hospital by ambulance. There was no contamination to the 
 body. 
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.
