Electricity Generated and Purchased in April 2003 (Bulletin)
(2003/5/16)

1. Nationwide Summary

Total electricity generated and purchased in April was up 3.6%, due to increased large industrial user demand. 69.10 billion kWh were generated.


Breakdown
Hydro
Flow rates were above those of last year, leading to a rise in hydro power generation. 7.40 billion kWh were generated, up 4.6%.

Thermal
Decreased use of nuclear power led to a 40.0% increase in thermal generation. 35.22 billion kWh were generated.

Nuclear
The capacity utilization rate at all companies was down compared to last year, resulting in a 42.7% decline in nuclear power generation. 15.07 billion kWh were generated.
Capacity utilization rates in 2003 and 2002 were 48.5% and 84.7% respectively (Japan Atomic Power Company figures excluded).

2. State of the Companies
Business results at all the companies rose due to increased industrial demand.
