Electricity Generated and Purchased in the First Half of 2003 (Bulletin)
(2003/10/17)

1. Nationwide Summary
Decreased demand for cooling caused by lower temperatures in July and August led to a decline of 1.5% to 454.07 billion kWh across the 10 companies.

Breakdown

Hydro
The flow rate was up compared to last year's first half, resulting in an increase of 16.7% to 44.94 billion kWh.

Thermal
Decreased use of nuclear power led to a 16.9% increase in thermal generation. 233.57 billion kWh were generated.

Nuclear
The capacity utilization rate at all companies was down compared to last year's first half, resulting in a 38.8% drop in nuclear power generation. 97.75 billion kWh were generated.

Capacity utilization rates in 2003 and 2002 were 51.6% and 84.4% respectively (Japan Atomic Power Company figures excluded).


2. State of the Companies

With the exception of Hokkaido, Kyushu and Okinawa, business results at the rest of the companies were down, due to decreased demand for cooling caused by lower temperatures in July and August.
