Kansai Electric Power has put figures on what revised grid charges mean for its customers. In a disclosure dated 29 September 2026, the utility said it decided that day to revise electricity charges from 1 November, and it filed a change notification for its regulated retail supply terms with the minister of economy, trade and industry under the Electricity Business Act.
Kansai cites a ministry news release of 11 September for the changes to the wheeling supply terms, and Tokyo Brief's earlier article covered the grid-charge rise. What is new is the company's own bill modeling and unit prices. Kansai says the revision reflects the change in wheeling charges, the fees for using a general transmission and distribution operator's network, which come in a demand-side and a generation-side form. Basic charges, minimum charges and per-kWh energy charges are each revised, and the content differs by plan.
Low-voltage households and small users
Kansai's modeled monthly bills rise between 4.3% and 6.9%. They include consumption tax but exclude the fuel cost adjustment and the renewable energy levy, so actual bills will move with those items. The regulated metered lighting plan A, modeled at 260 kWh a month, goes from ¥6,175 to ¥6,582, a 6.6% rise.
| Plan | Monthly use | Current bill | Revised bill | Change |
|---|---|---|---|---|
| Regulated metered lighting A | 260 kWh | ¥6,175 | ¥6,582 | +¥407 (+6.6%) |
| Regulated metered lighting B (11 kVA) | 1,180 kWh | ¥31,482 | ¥32,841 | +¥1,359 (+4.3%) |
| Regulated low-voltage power (8 kW) | 490 kWh | ¥14,909 | ¥15,743 | +¥834 (+5.6%) |
| Liberalized plan (10 kW) | 610 kWh | ¥14,067 | ¥14,876 | +¥809 (+5.8%) |
| Liberalized plan (6 kW) | 350 kWh | ¥8,416 | ¥8,885 | +¥469 (+5.6%) |
| Liberalized plan | 260 kWh | ¥5,883 | ¥6,291 | +¥408 (+6.9%) |
The unit prices behind plan A are uneven. The minimum charge for the first 15 kWh rises from ¥522.58 to ¥763.81, and each of the three energy tiers rises by ¥0.68 per kWh. Plan B's basic charge rises ¥50.61 per kVA to ¥497.82, and low-voltage power's basic charge rises ¥78.75 per kW to ¥1,211.46.
Charges for the Tokyo-area low-voltage segment are not in this notice. Kansai said it will announce them separately once preparations are complete.
High-voltage and extra-high-voltage users
The percentage rises are smaller here. On the current standard menu, the one that applies to contracts starting by 1 November and predates the 19 August revision, a modeled 820 kW high-voltage user drawing 230,000 kWh a month goes from about ¥5.49mn to about ¥5.61mn, up 2.3%. A 100 kW user drawing 16,500 kWh rises 2.9%. Extra-high-voltage examples, at 3,000 kW and 20,000 kW contracts, each rise 0.5%.
For new contracts from 1 November under the menu Kansai disclosed on 19 August, the same 820 kW example moves from about ¥5.83mn to about ¥5.95mn, up 2.1%. The extra-high-voltage examples again rise 0.5%. As with household plans, these are modeled bills at stated contract sizes and usage, excluding fuel, market-price and renewable adjustments, and rounded to the nearest ¥10,000. Rounding means the stated increase may not match the difference between the two printed bills.
Other terms changing
Three non-price items ride along. From 1 November, usage during a meter fault under regulated terms will be set through talks between Kansai and the transmission operators rather than with the customer; Kansai says the governing standard is unchanged and results should not differ in substance. From the same date, disaster relief measures such as payment extensions will require a disaster certificate only when needed, not as a rule. From 1 April 2027, in the liberalized segment, invoice-issuance fees can also be billed with the following month's charge, but only where bank-account or credit-card payment fails and Kansai issues a payment slip; some plans are excluded.
