1. Volume of power generated and purchased

(Units: GWh, %)

	March 2010	FY2009 2nd Half	FY2009
Power generated and purchased (% of previous year)	11,898 (109.7)	68,746 (102.0)	133,745 (94.7)
Internally-generated power Breakdown: Hydro power (% of previous year)	973 (125.4)	3,432 (119.4)	8,594 (109.1)
Internally-generated power Breakdown: Thermal power (% of previous year)	7,528 (98.0)	46,109 (97.7)	92,236 (97.2)
Internally-generated power Breakdown: Nuclear power (% of previous year)	1,678 (203.0)	9,749 (109.4)	14,130 (61.8)
Internally-generated power Breakdown: Wind power (% of previous year)	1 (-)	2 (-)	2 (-)
Received from other sources (% of previous year)	1,718 (110.2)	9,454 (112.6)	18,783 (120.7)

2. Maximum power monthly three-day average

(Units: MW, %)

	March 2010	FY2009 2nd Half	FY2009
Maximum power three-day average (% of previous year)	21,250 (104.6)	23,020 (102.7)	23,880 (85.5)

*Calculated by taking the average from the three days within the pertinent month on which the highest volume of electricity is recorded.

*The maximum power three-day average for the 2nd half occurred in January, and that for the fiscal year occurred in July.

3. Flow rate

(Unit: %)

	March 2010	FY2009 2nd Half	FY2009
Flow rate	164.1	111.5	102.4

*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: %)

	March 2010	FY2009 2nd Half	FY2009
Rate of use of nuclear facilities	64.4	63.7	46.0

*Hamaoka Nuclear Power Station Reactor No. 5 operations suspended from August 11, 2009 (periodic inspections from March 15,2010)
