Tariff rates
The tariff information below is effective for consumption on or after 1 Jan 2024. It applies to business customers that do not use electricity for residential purposes only.
The Non-residential Tariff is based on monthly meter-readings. It includes the following items:
This is the charge for electricity consumption. The rate is 106.0 cents per unit.
The Fuel Cost Adjustment amount may increase or decrease your bill. It is based on the difference between forecasted fuel prices and actual fuel prices (oil, gas and coal). The Fuel Cost Adjustment is updated every month to reflect the latest fuel price changes.
This rebate decreases your bill. It only applies to bills with a total monthly consumption of 400 units or less. Refer to the table below for the rebate rates:

The fuel cost adjustment amount may increase or decrease your bill. It is based on the difference between forecasted fuel prices and actual fuel prices (oil, gas and coal). The fuel cost adjustment is updated every month to reflect the latest fuel price changes.
To qualify for the High Load Factor Rider (HLFR), your average monthly total consumption per kVA of average monthly “Maximum Billing Demand” in the preceding 12 months must be more than 500 units per kVA.
HLFR lowers the energy charge for each unit over 500 units per kVA of Maximum Billing Demand in the month. The reduction in the energy charge is calculated at the following rate:
Reduction (cents/unit)
Each of the 501 to 600 unit per kVA of Maximum Billing Demand.
5.2
Each unit over 600 units per kVA of Maximum Billing Demand.

Pro-rated adjustments
If the period between 2 successive meter-readings is outside the 25 to 35 day range, your Energy Charge will be pro-rated.
Your adjustment will be made as follows:
Applicable block units = Normal block units x N / 30
N refers to the number of days between two successive meter-readings.
If the billing period is less than 22 days at the beginning or end of supply, your demand charge will be pro-rated.
Your adjustment will be made as follows:
Billed demand charge = Unadjusted demand charge x P / 30
P refers to the number of days in the period billed at the beginning or end of supply.

The tariff information below is effective for consumption on or after 1 Jan 2024. As a business customer, you may apply for Large Power Tariff if your current or expected demand is 3,000 kVA or more.
The Large Power Tariff (LPT) is based on monthly meter-readings. It includes the following items:
This charge is based on your monthly maximum demand in kilovolt-amperes (kVA) according to time periods. Demand Charges are higher during peak periods than off-peak periods.
Please refer to the table below for more information.
Period

Billing demand shortfall
If your maximum total billing demand is less than 3,000 kVA, you will be charged for a billing demand shortfall. To calculate the shortfall amount, we will take the difference between:
- 3,000 kVA; and
- Your on-peak billing demand or off-peak billing demand (whichever is higher).
The rate for billing demand shortfall is HK$120.3 per kVA short of 3,000 kVA.
This is the charge for electricity consumption. The rate varies according to time periods. Energy charges are higher during on-peak periods than off-peak periods.
Please refer to the table below for more information.
