1. Customers whose present or expected monthly consumption is not less than 20,000 units may apply to the Company in writing for supply under Bulk Tariff.

2. This Tariff is based on monthly meter-readings.

3. This Tariff will be the aggregate of the following items:

(a) Demand Charge

Based on the monthly maximum demand in kilovoltamperes (kVA):

On-Peak Period

Each of the first 650 kVA


Each kVA above 650


(Minimum on-peak billing demand : 100kVA)

Off-Peak Period

Each off-peak kVA up to the on-peak billing demand


Each off-peak kVA in excess of the on-peak billing demand


(b) Energy Charge

On-Peak Period

Total Monthly Consumption Block

Rate (Cents/Unit)

Each of the first 200,000 units


Each unit over 200,000


Off-Peak Period

Total Monthly Consumption Block

Rate (Cents/Unit)

Each unit


(c) Fuel Cost Adjustment

The fuel cost adjustment is 24.3 cents per unit.

The amount by which the actual cost of fuel is less or more than $700 per 44 gigajoules shall be credited or debited to the Fuel Clause Recovery Account. A fuel cost adjustment will, if appropriate, only be made following review of the cost of fuel and the balance of the Fuel Clause Recovery Account.

4. High Load Factor Rider

(a) The High Load Factor Rider (HLFR) is available to Bulk Tariff customers whose average monthly total consumption per kVA of average monthly "Maximum Billing Demand" in the preceding 12 months is higher than 500 units per kVA

(b) HLFR provides lower charges for energy consumption over 500 units per kVA of "Maximum Billing Demand" in the month

(c) The reduction in the energy charges to the customers will be calculated at the following rate:

Each of the 501st unit to 600th unit per kVA of "Maximum Billing Demand"

5.2 cents

Each unit over 600 units per kVA of "Maximum Billing Demand"

10.5 cents

5. This Tariff, the Supply Rules and other conditions are subject to revision from time to time.

6. Payment of any bill received later than the due date will be subject to a late payment charge of 5% of the original amount due.

7. A customer's application for supply under this Tariff may be refused if, within 12 months prior to such application, he/she has ceased to be supplied under this Tariff at his/her own request.

8. Customers' energy and demand charges shall be adjusted in the following circumstances on a pro-rata basis.

  • Energy Charge

If the period between two successive meter-readings is outside the 25-35 days range, an adjustment to the block size under paragraph 3 (b) of the respective applicable energy charge tariff rate will be made, as follows:

Applicable block units = Normal block units x N / 30

N = Number of days between two successive meter-readings 

  • Demand Charge

For any billing period less than 22 days at the beginning or end of supply, the demand charge will be calculated on a pro-rata daily basis, as follows:

Billed demand charge = Unadjusted demand charge x P / 30

P = Number of days in the period billed at the beginning or end of supply

Note: In this rate table,  

-"Unit" shall mean one kilowatt-hour (kWh) of electricity  

-"Monthly" shall mean the period of approximately one month between a meter-reading (including estimations) and the next one. -

"Maximum Billing Demand" is the higher of on-peak billing demand and off-peak billing demand for the month.  

-"Off-peak Period" is the daily period between 2100 hours and 0900 hours and all day Sundays and Public Holidays (i.e. General Holidays as defined in Holidays Ordinance).  

-"On-peak Period" comprises all other hours.
