1. Nationwide Summary
Increased demand from large industrial users led to a rise of 3.5% to 68.21
billion kWh across the ten companies.
Breakdown
Hydro
Flow rates were above average, leading to a rise in hydro power generation.
7.13 billion kWh were generated, up 11.1%.
Thermal
Increased use of hydro and nuclear power depressed thermal generation.
27.95 billion kWh were generated, down 3.5%.
Nuclear
The capacity utilization rate at all companies was up compared to last
year, leading to a 10.2% rise to 25.23 billion kWh.
2. State of the Companies
Business results at all the companies were up due to recovery in industrial
demand.
Monthly Peak Load
Combined peak load for the ten companies was 130.117 million kWh (recorded
at 15:00, 30 May), up 6.4% on last year.
Flow Rates
Although the companies in northern Japan recorded above-average flow rates,
flow rates at the companies in western Japan were below-average. As a result,
the flow rate across the nine companies was 94.9%.
