Electricity Generated and Purchased in September 2003 (Bulletin)
（2003/10/17）

1. Nationwide Summary

Total electricity generated and purchased in September was up 4.5%, due to increased demand for cooling caused by higher temperatures. 79.57 billion kWh were generated.


Breakdown
Hydro
Flow rates were above those of last year, leading to a rise in hydro power generation. 6.33 billion kWh were generated, up 44.6%.
Thermal
Decreased use of nuclear power led to a 12.5 rise in thermal generation. 41.29 billion kWh were generated.

Nuclear
The capacity utilization rate at all companies was down compared to last year, resulting in an 18.3% decline in nuclear power generation. 19.41 billion kWh were generated.
Capacity utilization rates in 2003 and 2002 were 62.5% and 76.6% respectively (Japan Atomic Power Company figures excluded).

2. State of the Companies
Business results were up at all companies due to increased demand for cooling caused by higher temperatures.
