1. Active energy is the energy which ensures functioning of all electrical appliances and devices in the household. Active energy of high tariff/calculated to the customers with two-tariff meters – represents electricity consumed in the period between 7:00am – 23:00pm (8:00am – 24:00pm in summer) during one billing period (30 days), when consumption is calculated at high tariff (high-tariff electricity).
2. Active energy of low tariff /calculated to the customers with two-tariff meters - represents electricity consumed in the period between 23:00pm – 7:00am (24:00pm – 8:00am in summer) during one billing period (30 days), when consumption is calculated at low tariff (low-tariff electricity).
3. Active energy of single tariff/calculated to the customers with single tariff meters – represents consumed electricity, as well as the price of consumed electricity during one billing period.
4. eactive energy of high/low tariff – reactive energy is not calculated to households. Reactive energy does not ensure operation of devices, i.e. it is not transformed into useful work; however, it is necessary because it ensures creating of magnetic field necessary for starting certain devices, such as: engines, transformers, fluorescent and street lighting…
Reactive energy is calculated depending on the period of consumption at high/low tariffs (high 7:00 – 23:00/8:00 – 24:00; low 23:00 – 7:00/24:00 – 8:00).
5. Reactive energy of low tariff – (explained above)
6. Consumption of indirect customer - is calculated exclusively to those customers that have indirect consumer and do not have own meter point, and the consumption cannot be invoiced separately. Amount of indirect consumption is deducted from the amount of direct consumption and it represents a monetary liability of indirect customer, on the basis of prior consent of both parties.
10. Power demand charge - Measured peak power demand of customers that have devices for continuous metering and registration of power demand in fifteen-minute intervals is the maximum load during a 15-minute interval of a monthly billing period at high-tariff, and in case of customers that have devices which are metering and registering only the peak power demand during high-tariff period, such registered power demand will be used. The power that may be drawn by a customer is specified in the electric power authorization.
11. Use of transmission capacity – amount which refers to use of transmission capacity is a price of lease for electricity transit from power plant to connection to the distribution network, i.e. to the direct customers (high voltage level KAP, Steelworks, Railway). Voltage level at power plant gate amounts to 24 kV which is not sufficient for economical electricity transit to longer distances. Transit to longer distances requires high voltages, such as: 35, 110, 220, 380 (400) kV and higher (e.g. voltages in Russia are up to 500, 750 and 1150 kV). Therefore, a transformer is placed in the power plant and it increases voltage to the required level and energy is transmitted to a distance at that voltage level. Transmission network (of 400, 220, 110 kV voltage level) is owned by Crnogorski Elektroprenosni Sistem to which EPCG every month pays the money collected on the basis of this item and that money is used for functioning, maintenance and modernization of transmission network.
12. Use of distribution capacity - amount which refers to use of distribution capacity is variable, i.e. depends on the consumption and it implies the price of electricity transit from the boundary point of the transmission network (transformer station 110/35 kV) to customers (households…) Money paid by customers for the use of distribution capacity is used for development and modernization of distribution network (transformer stations 35/10 kV; 10/0,4 kV; poles, 35 kV, 10 kV, 0,4 kV overhead/underground power lines).
13. 14. Losses in transmission system of high/low tariff – Each electricity transit from the power plant to distribution network connection, i.e. to direct customers (high voltage level KAP, Steelworks, Railway) implies certain level of electricity losses which are result of certain physical processes on conductors (heating…) Transmission losses represent an integral part of electricity selling price everywhere in the world, but most countries do not distinguish this item on the electricity bill. Percentage of losses is determined by ERA.
15. 16. Losses in distribution system of high/low tariff - Electricity transit both in transmission and distribution network implies certain level of electricity losses which are result of certain physical processes on conductors (heating…) Distribution losses represent an integral part of electricity selling price everywhere in the world, but most countries do not distinguish this item on the electricity bill. Percentage of losses is determined by ERA.
17. Supplier's fee – Functional unit Supply is a part of EPCG and it carries out activities of delivery and invoicing of electricity to tariff customers, as well as collection of receivables from electricity sales, i.e. to households, as well as to industrial and commercial customers. Supplier's fee is a fee which is paid by an electricity customer for the mentioned services of FU Supply. Supplier's fee is an integral part of the electricity selling price everywhere in the world, but most countries do not distinguish this item on the electricity bill. Amount of the fee is determined by ERA.
21. Common area electricity consumption – is exclusively calculated to the customers who live in apartment buildings for electricity consumed for lighting of entrances, accesses, operation of elevators, etc.
22. Fixed portion of the fee for use of distribution capacity – amount calculated to the customers at low voltage level (households…) and it refers to the costs of maintenance of distribution network (entire low voltage infrastructure including the meter of a customer). Amount under item 22 is fixed, i.e. the same for all customers. Maintenance costs are integral part of electricity selling price everywhere in the world, but most countries do not distinguish this item on the electricity bill. Amount of this fee is determined by ERA.
31. Discount - of 5 % is automatically calculated to the customers that duly settle their liabilities and do not have outstanding debts. Right to 5% discount is exercised by the customers that pay invoice for the previous month by the end of the current month.
32. Adjustment – if consumption is incorrectly calculated due to an error during meter reading or due to defect of meter, etc., adjustment will be made after customer's complaints and it will be given under item 32.
33. 34. 35. Subsidy I, II, III - the following customers are entitled to subsidies for electricity bill: social security beneficiaries, beneficiaries of disability allowance, of custodial care, of substitute family placement, as well as of beneficiaries of allowance for veterans. Subsidy for electricity bill implies 40% discount on the bill amounting up to €60, and if the amount of bill is higher, it will be reduced by €24. Subsidy is not automatically calculated but the right to subsidy is exercised by the customers who are allowed the subsidy on the basis of the submitted Application for subsidy.
41. VAT –value added tax
51. Amount of bill excluding VAT
52. Amount of bill including VAT
53. Previous debt – Amount of the previous debt of a customer excluding the amount of the current invoice
54. Payment – amount of the last payment
55. Interest – default interest is calculated to the previous debt for the bill older than 30 days (e.g. if a customer does not pay the bill for January, the interest will be calculated from March 1). Interest is determined semi-annually by Centralna banka Crne Gore and it is published in the Official Gazette of Montenegro. The interest rate in the last decision amounts to 8%.
