Electricity Generated and Purchased in October 2003 (Bulletin)
(2003/11/14)

1. Nationwide Summary

Total electricity generated and purchased in October was down 0.9%, due to decreased demand for cooling caused by lower temperatures. 71.23 billion kWh were generated.


Breakdown
Hydro
Flow rates were above those of last year, leading to a rise in hydro power generation. 4.21 billion kWh were generated, up 1.5%.
Thermal
Decreased use of nuclear power led to a 6.0 rise in thermal generation. 37.57 billion kWh were generated.

Nuclear
The capacity utilization rate at all companies was down compared to last year, resulting in a 15.4% decline in nuclear power generation. 18.06 billion kWh were generated.
Capacity utilization rates in 2003 and 2002 were 56.3% and 66.6% respectively (Japan Atomic Power Company figures excluded).

2. State of the Companies
Business results were down at Tokyo, Chubu, Kansai, Chugoku and Shikoku due to decreased demand for cooling caused by lower temperatures.
