We have announced "TEPCO Electricity Forecast" since July 1st, 2011 in our 
homepage. This time we found that there were some mistakes in the past 
electricity demand data. We correct these data and reflect today. 

Specifically, since a program to automatically calculate electricity 
demand results was not set up appropriately, receiving power from other 
companies newly received from July 1st was not reflected. Thus we correct 
all hourly data of electricity demand results from July 1st to August 17th, 
and then reflect them on our homepage. 

We have already improved the program since August 18th. Electricity demand 
results after August 18th are properly calculated. 

We apologize for your inconvenience.
