1. Volume of power generated and purchased

(Units: GWh, %)

	September 2010	FY2010 1st half total
Power generated and purchased (% of previous year)	12,417 (112.2)	71,431 (109.9)
Internally-generated power Breakdown: Hydro power (% of previous year)	634 (110.0)	5,536 (107.2)
Internally-generated power Thermal power (% of previous year)	8,568 (98.1)	47,271 (102.5)
Internally-generated power Nuclear power (% of previous year)	1,611 (461.8)	9,852 (224.9)
Internally-generated power Wind power (% of previous year)	1 (-)	6 (-)
Received from other sources (% of previous year)	1,603 (113.6)	8,766 (94.0)

2. Maximum power monthly three-day average

(Units: MW, %)

	September 2010	FY2010 1st half total
Maximum power three-day average (% of previous year)	26,560 (114.8)	26,980 (113.0)

*Calculated by taking the average from the three days within the applicable month on which the highest volume of electricity is recorded.
The days used to calculate the maximum power three-day average for the 1st half occurred in August.

 

3. Flow rate

(Unit: %)

	September 2010	FY2010 1st half total
Flow rate	80.1	111.2

*Flow rate = (Volume of hydro-generated electricity/Average hydro-generated electricity for past 30 years) ×100
Results greater than 100% denote high water flows; results less than 100% denote low water flows.

4. Rate of use of nuclear facilities

(Unit: %)

	September 2010	FY2010 1st half total
Rate of use of nuclear facilities	63.8	64.0

*Hamaoka Nuclear Power Station Reactor No. 5 operations have been suspended since August 11, 2009 (periodic inspection)
