Since the Tohoku -Chihou-Taiheiyo- Oki Earthquake on March 11, 2011, where
many of TEPCO's power stations have been shut down, we sincerely
appreciate all your understanding and support in saving electricity. 

We would like to announce here a detailed supply and demand outlook for
July and August (equal to 9 weeks), which we have compiled this time. 

In regard with the supply side, 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 56.8GW at the end of July, and 55.6GW at
the end of August. 
Also, in order to support balance of demand and supply 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 55.4GW at the end of July, and 54.2GW at the end of
August.

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 will also continuously ask for additional power supply (1GW) from 60Hz
areas, if the tight demand and supply balance is mitigated in these areas.

<Demand and Supply outlook of each weeks in July and August>    (Unit:GW)  *Maximum peak load is maximum demand outlook of each week,supply capacity
 is average of each week

<Supply and demand outlook at the end of July and August>       (Unit:GW) # Maximum peak load for the last summer was recorded 59.99 GW (July 23rd).
Estimated peak demand of 55 GW for this summer is 5GW lower than that of
least 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. 


<Additional capacity (changes after the May 13th report)>
①Recovery from the shutdown by earthquake disaster and start up from
  planned outage[July +2,200MW]
  Incorporated the acceleration of restoration schedule for Hirono Thermal
  Power Station Unit 1, 2, 4
②Increase of purchase of privately generated power reserve etc [+400MW]
③Reduction as a result of power supply [▲1,000MW]

*Pumped Storage Hydro of 6,500MW is incorporated in this outlook. In case
 of severe demand and supply balance conditions, storage amount of upper
 dam and demand trend at that moment will be taken in account and Pumped
 Storage Hydro capacity will be carefully examined and reflected.

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

                                                                       END
