Upon the Tohoku Electric Power Company's request via the Electric Power 
System Council of Japan (ESCJ) for the power supply in order to respond to 
the anticipated severe power demand-supply balance in its service area, 
TEPCO decided to provide power supply to Tohoku Electric Power Company of 
300 MW from 17:00 pm to 18:00 pm today in the form of Power Interchange 
while considering its own power demand-supply balance. 

This operation will not have any negative impact in the power supply in 
TEPCO's service area.  

<reference> Power Interchange (Power interchange across the service areas)
Power interchange conduced between electric power companies in order to 
secure the stable power supply as a nation in case of the power supply 
failure due to accident or demand-supply gap at the time of sharp demand 
increase. 
ESCJ takes a role as an agent in coordinating the power interchange. The 
electric power company asking for the additional power supply makes 
application for ESCJ. ESCJ then coordinate with other electric power 
companies who are capable of supplying power.
