We have decided to supply maximum of 1.4 GW to Tohoku Electric Power 
Company which suffered severe damage from the quake in order to support 
balance of demand and supply. In response to the request from Tohoku 
Electric Power Company, we are conducting power interchanges since August 
4 (previously announced on August 6). 

Our plan for today was to supply maximum of 800MW from 10:00 to 17:15 to 
Tohoku Electric Power Company. However, we received an additional request 
for a power supply (nationwide power exchange) from Tohoku Electric Power 
Company through the Electric Power System Council of Japan. In response to 
the request, based on the supply and demand balance in our service area, 
we have decided to supply additional power, maximum 300 MW as nationwide 
power exchange, from 13:30 to 18:00 today. 

We will be supplying maximum of 1.1 GW in total to Tohoku Electric Power 
Company in the above period today. However, we assume we can maintain 
proper reserve capacity. Therefore, there will be no problem in supplying 
stable amount of electricity in our service area.


 * Our supply capacity before power interchanges (54.3 GW) already 
   reflects the supply of 0.3 GW (300 MW) for Tohoku Electric Power 
   Company from August 8 to August 11and 0.5 GW (500MW) as power 
   interchanges (nationwide power exchanges). 

<Reference> Power interchanges (nationwide power exchanges)
Emergency power interchanges among general electricity utilities to secure 
stable supply and demand nationwide as a countermeasure to the gap between 
supply and demand due to faults in generators in operation and sharp 
increases in demand.
For the exchange of power, Electric Power System Council of Japan ("ESCJ") 
facilitates the process (the general electricity utility in need of 
additional power makes a request to ESCJ. ESCJ inquires other general 
utilities whether they can provide the power or not. By the offer(s) from 
general utiliti(es) who can provide supply, the power exchange is decided.)
