Electricity Generated and Purchased in September 2004 (Bulletin)

2004/10/15
FEPC

1. Nationwide Summary

Total electricity generated and purchased in September 2004 was up 0.4% across the ten companies to 79.89 billion kWh. The rise was due to increased large industrial user demand.

(Breakdown)

Hydro Flow rates were above those of last year, leading to a rise in hydro power generation. 6.63 billion kWh were generated, up 4.9%.
Thermal Increased use of hydropower led to a 0.9% decline in thermal generation. 40.90 billion kWh were generated.
Nuclear The capacity utilization rate at all companies was down compared to last year, resulting in a 2.8% decline in nuclear power generation. 18.87 billion kWh were generated.
Capacity utilization rates in 2004 and 2003 were 59.6% and 62.5% respectively (Japan Atomic Power Company figures excluded).

2. State of the Companies

Business results in Hokkaido, Tohoku, Tokyo, Chubu and Hokuriku rose due to bullish large industrial demand. Those in the rest of the companies declined due to decreased demand for cooling caused by lower temperatures in early September.

[Monthly Peak Load]

Combined peak load for the 10 companies was 155.64 million kWh (recorded at 15:00, 14 September), down 6.5% on last year.

[Flow Rates]

With the exception of Tohoku, flow rates at all the companies were above average. As a result, the flow rate across the nine companies was 121.0%.
