## Key takeaways

- Two-part power tariff distinctly separates fixed capacity charges from variable kWh usage.
- High load-factor industrial facilities can lower electricity expenses by 5% to 8%.
- Incentivizes production shifts into off-peak overnight hours, flattening grid peak demand.

The Ministry of Industry and Trade is finalizing the pilot framework for a two-component electricity pricing mechanism, marking a transition from Vietnam's traditional volumetric volumetric-only billing to international power market standards.

### Capacity and Energy Cost Allocation Flow

The reformed billing model delineates capital infrastructure expenditure from variable fuel combustion:

```flow
[
  "1. Industrial manufacturers contract peak operational demand (P_max) based on plant audits",
  "2. National grid dispatcher reserves substation capacity and transmission transmission headroom",
  "3. Grid operator bills fixed capacity charges (VND/kW) tied to reserved capacity limits",
  "4. Metering infrastructure bills volumetric energy consumption (VND/kWh) based on metered draw"
]
```

### Two-Part Electricity Billing Formula

Monthly utility costs under the two-component tariff are governed by:

$$\text{Total Bill} = C_{\text{capacity}} \times P_{\text{contracted}} + C_{\text{energy}} \times A_{\text{consumed}}$$

Where $C_{\text{capacity}}$ reimburses grid capital expenditure and network maintenance, while $C_{\text{energy}}$ recovers generation fuel expenses (coal, gas, renewables).

  }
}
```

### Volumetric Single-Part vs. Two-Component Tariff

| Metric | Legacy Volumetric Tariff | Modern Two-Component Tariff |
| :--- | :--- | :--- |
| **Billing Foundation** | 100% lumped into volumetric kWh | Clear split between capacity (kW) and energy (kWh) |
| **Operational Incentives** | No financial reward for flat load profile | Directly rewards 24/7 continuous stable power draw |
| **Cross-Subsidization** | High load-factor users subsidize peaky users | Eliminates cross-subsidies across customer classes |
| **Steel & Chemical Impact** | Capacity costs unoptimized | Saves 5% – 8% on electricity bills at high load factor |

### Grid-Wide Efficiency Dividends

The tariff encourages heavy industries to shift flexible batch operations into off-peak overnight hours, shaving peak grid demand and postponing costly peaker generation investments.

## Frequently asked questions

### What cost components comprise the two-part electricity tariff structure?

The structure splits billing into a fixed capacity charge (VND/kW of peak contracted demand) and a variable energy charge (VND/kWh consumed).

### Which consumer group is eligible for the initial regulatory pilot program?

The Ministry of Industry and Trade proposes piloting the scheme for large industrial manufacturing facilities consuming over 200,000 kWh per month.
