Electricity Generated and Purchased in September 2002 (Bulletin)
(2002/10/15)


1. Nationwide Summary
Total electricity generated and purchased in September was up 3.4%, due to increased demand for cooling caused by higher temperatures. 76.18 billion kWh were generated.

Breakdown

Hydro Flow fates were below those of last year, leading to a decline in hydro power generation. 4.37 billion kWh were generated, down 19.5%.

Thermal
Decreased use of hydro and nuclear power led to a 9.7% increase in thermal generation. 36.72 billion kWh were generated.

Nuclear
The capacity utilization rate at all companies was down compared to last year, resulting in a 1.4% decline in nuclear power generation. 23.77 billion kWh were generated.

Capacity utilization rates in 2002 and 2001 were 76.6% and 78.5% respectively (Japan Atomic Power Company figures excluded).


2. State of the Companies

With the exception of Okinawa, business results at all the companies were bullish due to increased demand for cooling caused by higher temperatures.

Monthly Peak Load
Combined peak load for the 10 companies was 1693.35 million kWh (recorded at 15:00, 3 September), up 14.0% on last year.
