TEPCO EP Residential Tariff Structure (従量電灯B)
1. Progressive 3-Tier Pricing Model
To encourage energy conservation while safeguarding essential living standards, Japan utilizes progressive inverted block tariffs:
- Tier 1 (First 120 kWh): ¥29.80/kWh — Basic essential lifeline consumption.
- Tier 2 (121 to 300 kWh): ¥36.40/kWh — Average household consumption rate.
- Tier 3 (Over 300 kWh): ¥40.49/kWh — Higher rate to discourage excess power use.
2. Fuel & Green Energy Adjustments
Every monthly power bill includes two floating adjustment lines:
The Fuel Cost Adjustment (燃料費調整額) reflects changes in global crude oil, coal, and liquefied natural gas prices compared to TEPCO's regulated standard base price.
The Renewable Energy Surcharge (再エネ賦課金) is set annually by METI to finance national solar, biomass, and wind feed-in tariffs across Japan.
Frequently Asked Questions
How is the TEPCO Metered Lighting B (従量電灯B) base charge calculated by amperage? ▼
TEPCO charges a fixed monthly base fee (基本料金) determined strictly by the breaker amperage installed in your residence: 10A (¥311.75), 15A (¥467.63), 20A (¥623.50), 30A (¥935.25), 40A (¥1,247.00), 50A (¥1,558.75), and 60A (¥1,870.50). Most typical 1-2 person apartments use 30A, while family homes use 40A to 50A.
What are the 3 consumption energy rate tiers for TEPCO residential plans? ▼
Energy charges (電力量料金) are progressive across three tiers: (1) First Tier (up to 120 kWh): ¥29.80/kWh (lifeline rate), (2) Second Tier (121 to 300 kWh): ¥36.40/kWh (standard household consumption), and (3) Third Tier (above 300 kWh): ¥40.49/kWh (high consumption usage rate).
What is the Fuel Cost Adjustment (燃料費調整額 Nenryouhi Chouseigaku)? ▼
Because Japan imports almost all of its fossil fuels (LNG, coal, crude oil), TEPCO applies a monthly Fuel Cost Adjustment per kWh consumed. When import fuel costs drop below baseline reference prices, this adjustment becomes a negative credit (discounting your bill); when global energy prices surge, it is billed as a positive surcharge.
What is the Renewable Energy Promotion Surcharge (再エネ賦課金 Saene Fukakin)? ▼
Mandated by the Ministry of Economy, Trade and Industry (METI) under the Feed-in Tariff (FIT) law, the Renewable Energy Surcharge is a uniform nationwide fee levied on every kilowatt-hour consumed (set at ¥3.49/kWh for FY2024/2025) to fund renewable solar and wind grid integration.
Does Japanese Consumption Tax (10% JCT) apply to electricity bills? ▼
Yes. All component tariffs (base charge, tier 1-3 energy consumption, fuel adjustment, and renewable surcharge) are subject to standard 10% Japanese Consumption Tax, which is already integrated into the regulated METI retail unit prices.
