Tariff for Electric Means of Transport ^[1] is applicable to electricity supplied by medium or low voltage and used for charging of electric means of transport.

 

According to the power consumption characteristics of electric means of transport, the tariff is classified into Public Charging Tariff and General Charging Tariff. 

 

Subscribed Voltages

Low voltage (LV):  230/400 V

Medium voltage (MV): 11,000 V

Public Charging Tariff

 

Public Charging Tariff is applicable to the charging facilities set up by CEM in public car parks and public parking spaces. Based on the rated output power of the charging facilities, Public Charging Tariff is charged according to "time-of-use" and "charging duration". 

• Slow Charge : Charge based on "time-of-use".
• Medium / Quick Charge : Charge based on charging duration

 Public Charging Tariff is charged per each charging transaction and is calculated based on the following items: 

 

Subscribed Demand (in unit of kVA)
The rated maximum output power of the charging facilities selected by user.
 

Consumption (in unit of kWh)
Total units of electricity consumed during the charging period.
 

Tariff Clause Adjustment 
Adjustment in tariff to reflect fluctuation in energy production cost that is fixed quarterly.

Rated Output Power	Tariff Periods	Time	Subscribed Demand (MOP/kVA)	Consumption (MOP/kWh)
Slow Charge (Up to 7.4 kW)	Low-load hours (10 hours)	23:00 - 09:00	0.00	1.420
	Full-load hours (14 hours)	09:00 - 23:00	0.00	2.150
Medium Charge (Above 7.4 kW to 25 kW)	First period	Within the first 60 minutes	0.00	3.430
	Subsequent period	Afterwards	0.00	3.940
Quick Charge (Above 25 kW)	First period	Within the first 30 minutes	0.00	3.830
	Subsequent period	Afterwards	0.00	4.400

Calculation method:

Charging fee = Demand + Energy charged (kWh) x (Consumption + TCA)

Example:

Generally, the battery capacity of electric vehicles (EVs) on the market is about 80 kWh. If it is charged from a remaining power level of 20% to 80%, 48 kWh is required to be charged. The following are the costs at different charging speeds and time periods. No matter which one is selected, it is cheaper than fuel.

 

Charging Speed	Charging period	Time required	Charging fee  (MOP)
Slow Charge	Low-load hours	Approx.7 hours	48 kWh x ($1.420+$0.400) = $87.36
	Full-load hours		48 kWhx ($2.150+$0.400) = $122.40
Medium Charge	First 60 minutes: 14.5 kWh Afterwards: 33.5 kWh	Approx. 2.5 hours	First 60 minutes:14.5 kWh x ($3.430+$0.400) =$55.54 Afterwards：33.5 kWh x ($3.940+$0.400) = $145.39 Total: $200.93
Quick Charge	First 30 minutes: 14.7 kWh Afterwards: 33.3 kWh	Approx. 1.5 hours	First 30 minutes:14.7 kWh x ($3.830+$0.400) = $62.18 Afterwards：33.3 kWh x($4.400+$0.400) = $159.84 Total: $222.02

Remarks：

- Based on the oil price in June 2022, which is MOP 13.32/liter (including discounts).

- TCA in Q3 of 2022 is MOP 0.400.

- The energy charged for the first period of quick and medium speed is 30%, while 70% for the subsequent period.

- Slow charge is calculated at complete full-load hours and low-load hours, while private charging is calculated by charging 10 times a month (once every 3 days), with 20 kWh per charge.

- Considering the differences in model, battery status, charging rate and charging mode of EVs, the calculation results are for reference only. The actual cost is subject to the actual charging conditions.

General Charging Tariff

 

General Charging Tariff, namely private charging, is applicable to the charging facilities not covered by the Public Charging Tariff.  General Charging Tariff is charged according to "time-of-use".

General Charging Tariff is charged according to the total charging consumption in a month and is calculated based on the following items:

 Subscribed Demand (in unit of kVA)
Maximum electric load available as stated in the supply contract and controlled by the meter size and protection device.

 

Consumption (in unit of kWh)
Total units of electricity consumed during the billing period.

  

Tariff Clause Adjustment (TCA)
Adjustment in tariff to reflect fluctuation in energy production cost that is fixed quarterly.

  

Government Tax 
Monthly tax payable for the usage of electrical installation.

Demand

Subscribed Demand	Subscribed Demand Charge
Up to 3.4 kVA	8.224 (MOP)
Above 3.4 kVA to 6.9 kVA	18.796 (MOP)
Above 6.9 kVA	3.372 (MOP/kVA)

Consumption

Tariff Period	Time	Consumption
Low-load hours (10 hours)	23:00 - 09:00	0.817 (MOP/kWh)
Full-load hours (14 hours)	09:00 - 23:00	1.552 (MOP/kWh)

 

Calculation method:

Charging fee = Demand + Energy charged (kWh) x (Consumption + TCA)+ Government tax

Example:

	Unit	Unit Price (MOP)	Amount (MOP)
Demand	6.9 kVA		18.80
Consumption (low-load hours)	160 kWh	0.817	130.72
Consumption (full-load hours)	40 kWh	1.552	62.08
Tariff Clause Adjustment	200 kWh	0.400	80.88
Government Tax (0.75 x √6.9)			2.00
Total			293.60
