Unusually hot summer weather in Tokyo is putting pressure on the city’s power supply, leading the local utility to ask people to use electricity wisely.
Hot weather at the beginning of summer in the northern hemisphere is increasing the need for electricity and tightening the global supply of fuels like gas and coal.
Bloomberg reported that the LNG market is already finely balanced, and prolonged heat in Japan could drive up prices in Asia and Europe.
The price of electricity in Tokyo surged to 21.9¥ per kilowatt-hour this week, the highest since February 2023. According to Bloomberg data, temperatures in the city are expected to reach around 30°C, much higher than the normal 24°C over the past 30 years.

In Japan, unexpected maintenance has reduced electricity generation. A 413-megawatt unit at the Kawasaki gas-fired power plant was recently shut down. At the Kashima Kyodo facility, a 300-megawatt unit will be offline for some time, according to data from the Japan Electric Power Exchange.
Tokyo Electric Power Co. (Tepco) issued a warning about tight power supply, prompting Japan’s grid coordinator to direct a neighbouring utility to share an additional 200 megawatts of capacity.
Consequently, Jera, a joint venture between Tepco and Chubu Electric Power Co., has increased power generation at several plants by nearly 400 megawatts to meet demand in the Tokyo area.
Calls for power conservation are common during peak demand periods in summer and winter, although Japanese authorities have reassured that there is sufficient capacity for this season.
