Press Release (May 19,2009)
Performing a Series of Functional Tests for the Entire Plant of the Kashiwazaki-Kariwa Nuclear Power Station Unit No.7 after the Niigata-Chuetsu-Oki Earthquake (Starting generation by temporary main generator synchronization)
The Kashiwazaki-Kariwa Nuclear Power Station Unit No.7 (ABWR: 1,356MW) had been shut down 
since the Niigata-Chuetsu-Oki Earthquake occurred on July 16, 2007. On May 8, 2009, we started 
a series of functional tests for the entire plant, and are performing the pre-planned tests. 

Today, activating a main turbine generator, we started generation by temporary main generator 
synchronization at 6:59p.m.* 

After raising generating power to approx. 20% of the rated output and conducting the pre-planned 
tests, once we will isolate the main generator from the transmission network, and then, will 
verify the function of protective devices of the main turbine generator. Subsequently, we will 
connect the main generator to the transmission network again, and start full-scale generation. 

We will disclose test evaluation results accordingly. 

* Starting generation by temporary generator synchronization: 
 "Starting generation by temporary generator synchronization" is to connect a turbine generator 
 to our transmission network in order to verify the soundness of generator and main transformer, etc.
 Because of this, electricity produced at the Kashiwazaki-Kariwa Nuclear Power Station came to 
 the Tokyo metropolitan area, the first time after the Niigata-Chuetsu-Oki Earthquake. 
 After verifying the soundness, once we will isolate the turbine generator from the transmission 
 network. Subsequently, we will connect the generator to the network again, and start full-scale 
 generation.
