2005/4/15
FEPC

1. Nationwide Summary

Total electricity generated and purchased in the second half of FY2004 was up 2.1% across the ten companies to 469.17 billion kWh (up 2.7% adjusted for leap year). The rise was due to increased demand for heating caused by lower temperatures in winter.

(Breakdown)

Hydro Flow rates were above that of the previous year's second half, leading to a rise in hydroelectric generation. 29.66 billion kWh were generated, up 8.1%.
Thermal An overall increase in generated and purchased electricity led to a 1.3% rise in thermal generation. 235.43 billion kWh were generated.
Nuclear Although the capacity utilization rate at all companies was down compared to last year due to test operations, nuclear power posted an increase of 1.6%. 124.73 billion kWh were generated.
Capacity utilization rates in the 2nd half of FY2004 and FY2003 were 64.2% and 64.8% respectively (Japan Atomic Power Company figures excluded).

2. State of the Companies

Business results at all companies rose due to increased demand for heating caused by lower temperatures in winter.

[ Monthly Peak Load ]

Combined peak load for the ten companies was 149.684 million kW (recorded at 18:00, 1 February), remaining even with results for the same period 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 121.3%.
