Electricity Generated and Purchased in April 2002 (Bulletin)
1. Nationwide Summary
Total electricity generated and purchased in April was down for the ninth
consecutive month, falling by 0.2%. The decline was due to depressed large
industrial user demand. 66.68 billion kWh were generated.
Breakdown
Hydro
Flow fates were above those of last year, leading to a rise in hydro power
generation. 7.08 billion kWh were generated, up 19.7%.
Thermal
Increased use of hydro power, coupled with increased purchasing of power
from other power suppliers, led to a 7.2% decline in thermal generation.
25.15 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. 26.30 billion
kWh were generated.
Capacity utilization rates in 2002 and 2001 were 84.7% and 88.8% respectively
(Japan Atomic Power Company figures excluded).
2. State of the Companies
With the exception of Okinawa and Kyushu, business results at the rest
of the companies declined due to sluggish industrial demand. Monthly Peak
Load Combined peak load for the 10 companies was 116.338 million kWh (recorded
at 15:00, 17 April), down 3.8% on last year.
Flow Rates
Although flow rates at Chugoku, Shikoku and Kyushu were below average,
those at the rest of the companies were above average. As a result, flow
rate across the 9 companies was 103.0%.
