Key facts
- Japan's day-ahead electricity price reached $0.16 per kWh, a 20% weekly increase.
- This marks the highest power price in Japan since January 2023.
- An intensifying heatwave is expected to further boost electricity consumption.
- Middle East supply disruptions have significantly increased Japan's LNG and oil import costs.
- Japan has been increasing its use of coal for power generation due to high gas prices.
Japan's nationwide day-ahead electricity price has surged by 20% in a week, reaching its highest level since January 2023. The price settled at $0.16 (25.18 Japanese yen) per kilowatt-hour on Monday, according to data from the Japan Electric Power Exchange cited by Bloomberg.
The surge is attributed to a combination of factors, including an intensifying heatwave expected to peak mid-week, which is driving up consumption, and supply disruptions in the Middle East that are increasing fuel costs. LNG prices have reportedly doubled from before the recent conflict began, with Qatar's supply being affected by blockages in the Strait of Hormuz.
As a result of elevated LNG prices, Japan, a major importer of the fuel, has been increasing its reliance on coal for power generation, a trend also observed across other Asian countries seeking more affordable and available energy sources. The overall increase in oil prices has also contributed to a higher import bill for Japan.
Spot LNG prices for October delivery into Northeast Asia reached a five-month high due to renewed hostilities in the Middle East and the blockage of the Strait of Hormuz. Consequently, fuel costs for power supply in resource-poor Japan have climbed to their highest point in over three and a half years.
