TEPCO has been concentrating every effort to secure electricity supply 
since the Tohoku -Chihou-Taiheiyo- Oki Earthquake, where many of TEPCO's 
power stations have been shut down, as we will be able to foresee securing 
additional capacity, we will restate our peak demand supply capacity of 
this summer will be around 55.2 GW to 56.2 GW upward.
In addition, in order to continue avoiding the rolling blackouts, as it 
is still necessary that we will continue to exert utmost effort to 
strengthen the capacity for power supply as well as would also like to 
ask our customers to cooperate in reducing electricity consumption in 
summer time in light of the "Outline of Countermeasures for Power Supply 
and Demand During Summertime" presented by the Electricity Supply-Demand 
Emergency Response Headquarters of the Japanese government, we have 
summarized our efforts as outlined below.

1.Supply and Demand Status and Outlook
  Due to the foreseeable restoration of all the thermal power stations 
  except for those under long-term scheduled shut down, newly installment 
  of gas turbine generators and further improvement of usage of pumped 
  storage hydro, we will restate our peak demand supply capacity of this 
  summer will be around 55.2 GW (at the end of July) to 56.2 GW (at the 
  end of August) upward.
  Through implementing both supply and demand side countermeasures of 
  this summer, we will contribute by supplying electricity maximum of 
  1.4 GW to mitigate demand supply balance of Tohoku area where suffered 
  from huge damages by disaster. Hence, taking electricity supply to 
  Tohoku area into consideration, the peak demand supply capacity will be 
  around 53.8 GW (at the end of July) to 54.8 GW (at the end of August).
  As it will be anticipated the occurrence of unplanned outage of aged 
  thermal power stations or sudden increase of demand due to unexpected 
  high temperature summer may cause difficulties in maintaining stable 
  demand supply balance, in order to continue to avoid rolling blackouts, 
  we will continue our efforts to steadily implement countermeasures on 
  supply side and ensure additional capacity.



<Additional capacity (changes after the April 15th report)>
(1) Installment of Gas Turbine Generator
    [July +200MW (800MW in total), August +300MW (1,500 MW in total)]
(2) Recovery from the shutdown by earthquake disaster and start up from 
    planned outage
    [July +600MW, August +2,800MW]
    Incorporating all the unit of thermal power stations except for the 
    unit 5 to 8 (each 350 MW) of Yokosuka Power Station which is under 
    long-term scheduled shutdown.
(3) Others
    [▲100MW]
    Net of purchase of excess power of privately owned power generation 
    (increase) and supply from outside supply area (decrease).
(4) Utilization of Pumped Storage Hydro
    [+2,500MW (6,500 MW in total)]

2.Demand-Side Countermeasures (changes after the April 15th report)
  For the purpose of securing stable supple demand balance of this summer 
  period, in light of the "Outline of Countermeasures for Power Supply and 
  Demand During Summertime" presented by the Electricity Supply-Demand 
  Emergency Response Headquarters of the Japanese government today, we 
  will ask to every level of our customers corporations to save power use. 
  We strongly encourage our customer for further corporation to save power 
  usage.

(1) Customers above 500 kW of contract capacity
    ·visit all the customers to encourage saving power usage
    ·solicit demand and supply adjustment contract and expansion
    ·facilitate use of self generating facilities

(2) Customers below 500 kW of contract capacity receiving high-voltage 
    electricity
    ·encourage saving power usage to all customers and ask for the 
      decrease of contract capacity
    ·set up dedicated consultation dial for the customers

(3) Customers receiving low-voltage electricity
    ·endorse to encourage saving power usage to the electricity invoice
    ·distribute teasers
    ·encourage saving power usage to all customers at every opportunity

(4) Encourage saving power usage through media
    ·TV, radio, website, mobile site, Twitter (each includes "Denki
      (Electricity)" Forecast)

(5) Re-examination of implementation of rolling blackout
    ·Review methodology of implementation of rolling blackout which is 
      "avoidance in principle" in anticipation of such situation.

We sincerely apologize for the inconvenience caused, but appreciate your 
corporation to save power usage.
