Japan’s spot power prices surged over the weekend, with fuel‑cost pressures pushing rates in Tokyo and Chubu to multi‑year highs. Next‑day spot prices climbed 1.1% to ¥36.11 ($0.2)/kWh in Tokyo and 7.2% to ¥36.29/kWh in Chubu on Sunday—the highest since September 2022, per Japan Electric Power Exchange data. The nationwide average fell 8.7% to ¥30.09/kWh. Spot LNG prices extended gains to about $34 per million BTU on Friday, more than triple pre‑war levels. LNG flows through the Strait of Hormuz remain below one‑third of pre‑conflict rates. Average household electricity bills in Tokyo are projected to reach a record ¥9,738 in November, driven by rising fuel costs from Middle‑East conflict. If the surge continues, bills could soon exceed ¥10,000, warned Tokyo Electric Power Co. Executive Vice President Hiroyuki Yamaguchi. Japan’s fuel‑cost adjustment system automatically reflects LNG, crude oil, and coal import price changes in electricity rates based on a three‑month average. Escalating tensions after a Pakistani LNG carrier was attacked near the Strait of Hormuz could prolong the waterway’s effective closure, further driving fuel costs higher and pressuring utilities.
The situation highlights how geopolitical disruptions in energy chokepoints directly impact consumer electricity costs and utility profitability in Japan.
