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) 
 
-We calibrated water level gauge of the reactor of Unit 1 from May 10 
 to 11. 
 
-We calibrated pressure gauge of the primary containment vessel of 
 Unit 1 on May 11. 
 
-The pump to inject nitrogen to Unit 1 is stopped from 8:51 am on May 11 
 since part of power source of Unit 1 & 2 has been switched to Okuma Line 
 No.2. 
 
-We have restarted to transfer the accumulated water in the turbine 
 building of Unit 6 to the temporary tank at 10:00 am on May 11. 
 
-Spraying the dust inhibitor to areas including nearby Solid Waste 
 Storing Facility has been carried out in conventional method as of 
 May 11.

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
-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.
