Fuel-cost and other adjustment rates for November 2026 have been published, with rates from low voltage to extra-high voltage changing from the previous month. An estimate of the impact on households has also been provided.
On 29 September 2026, the average fuel prices for June to August 2026, reflecting August 2026 prices for crude oil, LNG and overseas coal, were finalized, and the details of fuel-cost and other adjustments to electricity rates for November 2026 were published.
The fuel-cost and other adjustment rate for low voltage was -¥4.54 for November, a change of +¥3.50. The high-voltage rate was +¥0.75, a change of +¥1.92, and the extra-high-voltage rate was +¥0.74, a change of +¥0.12. All figures include the equivalent of consumption tax and are presented before discounts under the government support program are applied.
For the estimated household impact, the model for metered lighting B, 30A and 230kWh/month shows a basic charge plus energy charge of ¥10,154, a fuel-cost and other adjustment of -¥1,044, a renewable-energy surcharge of ¥961 and a total bill of ¥10,071 for November 2026. This represents an impact of +¥805 compared with October 2026.
