Electricity Generated and Purchased in Fiscal 2004 (Bulletin)

2005/4/15
FEPC

1. Nationwide Summary

Total electricity generated and purchased in FY2004 was up 3.7% across the ten companies to 947.60 billion kWh (up 4.0% adjusted for leap year). The rise was due to increased demand for heating and cooling caused by low winter temperatures and record high summer temperatures.

(Breakdown)

Hydro Although the flow rate was up on last year, decreased use of pumped-storage hydroelectric power resulted in a 2.0% decline in hydroelectric generation. 70.91 billion kWh were generated.
Thermal Increased use of nuclear power resulted in a 1.8% decline in thermal power generation. 457.78 billion kWh were generated.
Nuclear The capacity utilization rate at all companies was up compared to last year, resulting in a 19.0% increase in nuclear power generation. 262.48 billion kWh were generated.
Capacity utilization rates in FY2004 and FY2003 were 67.8% and 58.2% respectively (Japan Atomic Power Company figures excluded).

2. State of the Companies

Business results at all companies rose due to increased demand for heating and cooling caused by low winter temperatures and record high summer temperatures.

[ Monthly Peak Load ]

Combined peak load for the ten companies was 174.00 million kWh (recorded at 15:00, 20 July), up 4.0% on last year.

[ Flow Rates ]

With the exception of Hokkaido, flow rates at all the companies were above average. As a result, the flow rate across the nine companies was 110.8%.
