Electricity prices in Japan have recorded a notable rise, reaching their highest levels in about four years, driven by the continuous increase in coal and liquefied natural gas (LNG) costs. This increase has been reflected in spot market indices, which saw significant weekly gains exceeding twenty-five percent, amid clear challenges facing the global energy supply system that directly impact local generation costs.
Record jumps in spot prices
Data from the Japan Electric Power Exchange showed that the spot price of electricity for delivery the next day reached a record level, recording 31.15 yen, equivalent to 19 US cents per kilowatt-hour across the country. The wave of increases included all major consumption areas, as prices jumped on a weekly basis by 61 percent in the Kansai region, while they recorded a 19 percent increase in the Tokyo and Chubu regions amid rising consumption and operational pressures.
Implications of the supply and gas crisis
Tensions and disruptions in LNG supplies have increased pressure on the Japanese energy sector. These conditions pushed many markets toward reliance on coal as an alternative to ensure security of supply, leading to a global surge in demand amid the inability of production in Indonesia, one of the most prominent coal-exporting countries, to meet the accelerating pace of demand. As a result, Newcastle coal futures exceeded the $150 per ton barrier, recording an increase of about 30 percent compared to pre-crisis levels, with the upward trend in prices continuing since late last August.
Declining generation capacity and maintenance work
The surge in fuel prices coincided with the implementation of routine and planned maintenance work at Japanese power plants. Official exchange data showed a decrease in available electricity production capacity by about 12 percent compared to the previous period. The overlap of some power plants shutting down for maintenance with fuel supply bottlenecks contributed to imposing tight conditions on the supply side of the local electricity market as winter approaches.
