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 pre-planned tests. 

The unit began generating power on May 19, and reached 100% rated electric output at 3:00 p.m. on 
June 5, 2009. We have confirmed operating status to be satisfactory by 7:30 p.m. on the same day. 

We will raise the power until reaching constant operation at rated thermal output, after which 
we will perform pre-planned tests carefully. Constant operation at rated thermal output is 
likely to lead to an electric output of about 1,400 MW.

We will disclose test evaluation results accordingly. 

* "Constant Operation at Rated Thermal Output": 
"Constant Operation at Rated Thermal Output" is an operational mode in which a unit is 
operated with the reactor thermal output being kept constant at 100%. 
The Kashiwazaki-Kariwa Nuclear Power Station has been operating all its units at constant 
operation at rated thermal output since 2002, after receiving confirmation from the Nuclear 
and Industrial Safety Agency of the Ministry of Economy, Trade and Industry on the validity 
of safety evaluation of generation facilities during such operational mode. Unit 7 had been 
operating in constant operation at rated thermal output since August 16, 2002.
