This is the coefficient that converts the consumption measured by the meter, expressed in cubic meters, into the unit of measurement used for billing, i.e., Standard Cubic Meters. The conversion coefficient C is necessary because the volume of the same quantity of gas, and therefore the same energy content, depends on the pressure and temperature at which that quantity is delivered. For example, the same quantity of gas occupies a different volume depending on whether it is delivered to a seaside or mountain location. To ensure that all customers pay the same amount for the same amount of energy consumed, this conversion is necessary: ​​for example, if the consumption measured by the meter is 110 cubic meters and the value of the coefficient C is 1.027235, then the standard cubic meters billed will be: 110 x 1.027235 = 112.99585 Smc.

Electricity costs differently depending on when it's used: during the day, when electricity demand is highest, it costs more; in the evening, at night, and on holidays, it costs less. All installed electronic meters will be programmed to record customer consumption by distinguishing the time slots in which it occurs (F1, F2, F3). These time slots have been defined by the Energy Authority. For supplies to large users connected to high or medium voltage, it's possible to access a system, called multi-time slots, which provides different purchase rates depending on the time slot of the day: for peak hours (F1), high load hours (F2), medium load hours (F3), and off-peak hours (F4). The daily and weekly distribution of these time slots is different for medium voltage supplies than for higher voltage supplies.

Electricity supply taxes are: State consumption tax (excise duty), municipal surcharge, and provincial surcharge. They are applied to the amount of energy consumed and provide, for "domestic use" customers, a tax relief system for supplying electricity to their registered residence, which reduces or exempts the amount in the case of low consumption. Surcharges were abolished on January 1, 2012 in ordinary statute regions and on April 1, 2012 in special statute regions. Value added tax (VAT). It is applied to the total cost of the service, and currently the rate applied to energy supply for "domestic use" customers is equal to the reduced rate; for "other uses" customers, it is equal to the standard rate.

Taxes include the state excise tax, the regional surcharge, and the value added tax (VAT). The state excise tax for "civil uses," including domestic uses, varies between the two macro-zones of North-Central and South-Central (formerly Cassa del Mezzogiorno) and also varies based on four consumption brackets: 0-120, 120-480, 480-1560, and over 1560 Smc. The state excise tax for "industrial uses" has a single rate for consumption up to 200,000 Smc. The regional surcharge is determined independently by each region through its own provision, taking into account the limits imposed by general tax legislation. Value Added Tax (VAT), calculated on the sum of all items on the bill, including excise duties, is reduced for civil uses (and therefore also for domestic uses) for the first 480 cubic meters consumed in the year, and is standard for all other consumption and fixed amounts. For customers with "industrial uses," the standard rate is always applied, unless the customer requests the application of the reduced rate as provided by law.

It covers additional gas supply costs (costs arising from the activities of wholesale suppliers of last resort for the period 2006-2007 and from the contribution to limiting gas consumption). In provisions establishing or modifying the economic conditions of protected gas supply, this item is technically referred to as QOA. It does not apply to customers with free market contracts.

These are charges, payable by all users of the service or by all users who fall within a certain category. They serve to offset costs incurred in the general interest of the system, for example, to support solidarity efforts in the event of natural disasters or for social benefits.

General charges are established by law and are paid by all end-users of electricity services; they are included in the bill as Network Services. They are intended to cover various charges: Component A3: promotion of energy production from renewable and similar sources; Component A4: financing of special tariff regimes; Component A5: financing of research and development activities; Component A6: coverage of costs already incurred by companies and not recoverable following the liberalization of the electricity market; Component AS: coverage of charges arising from the adoption of tariff protection measures for electricity sector customers experiencing economic and/or physical hardship pursuant to the Interministerial Decree of December 28, 2007; Component UC4: coverage of tariff supplements for smaller electricity companies; Component UC3: coverage of cost equalization mechanisms for electricity transmission, distribution, and metering; Component UC7: to cover costs arising from measures and interventions to promote energy efficiency in end-use applications; Components A2 and MCT: decommissioning of nuclear power plants and territorial compensation measures.

It's a 14-digit code that identifies the physical point where natural gas is delivered by the supplier and collected by the end customer. Since it identifies a physical point on the distribution network, the code doesn't change even if you change supplier.

These are the natural energy losses generated during the transport of electricity from the power plant to the point of supply. They are conventionally set by the Energy Authority at 10.8% of the energy withdrawn: that is, if 110.8 kWh of electricity is injected from the generation plant into the transport grid on behalf of the supplier, 100 kWh of this electricity arrives at the withdrawal point (for example, the customer's home). Energy prices can be expressed net of grid losses, or they can include them. Depending on the case, grid losses can be invoiced in different ways that do not affect the total amount payable.

Energy losses that occur during the transmission of electrical energy in electrical networks at different voltage levels. The electrical energy losses of a network, over a given period, are calculated as the difference between the energy fed into the network and its consumption.

It includes the months from April to September.

It includes the months from January to March and from October to December.

It's a code composed of letters and numbers that reliably identifies the physical point where energy is delivered by the supplier and collected by the end customer. Because it identifies a physical point on the distribution network, the code doesn't change even if you change supplier.

Corresponds to the power contracted at the user

This is the maximum drawable power, above which the energy supply may be interrupted due to the meter automatically tripping. For customers with contractually committed power up to 30 kW, the available power corresponds to the contracted power plus 10%.

This is the power level indicated in the contracts and made available by the supplier (technically, this is called contractually committed power). The committed power is defined based on the customer's needs at the time of signing the contract, based on the type (and number) of electrical appliances typically used. For most homes, and therefore domestic customers, the committed power is 3 kW.

This parameter indicates the energy supplied to the customer through a standard cubic meter of gas; it is used to convert gas consumption, expressed in cubic meters, into gas consumption valued in terms of energy (a relevant parameter for the end customer). The PCS parameter, in fact, represents the amount of energy contained in a cubic meter of gas supplied at standard temperature and pressure conditions.

Energy prices, based on the supply contract, can be classified as single-rate, dual-rate, or multi-rate. The price is called single-rate when it is the same throughout the day; dual-rate when it varies based on two different time slots (F1 and F2+F3); and multi-rate when it varies for each of the three time slots (F1, F2, F3).

These are the unit prices paid by the customer for each kWh of energy, kW of power, Smc of gas or per unit of time (days, months, years).

Some unit prices have a differentiated value for annual consumption brackets. Each bracket is between a minimum and a maximum level (e.g., 0-1800 kWh; 1801-2640 kWh, etc.). On each bill, the kWh billed are divided into the applicable brackets based on the customer's average daily consumption. For example, if the customer's average daily consumption is 8 kWh, the average annual consumption is 8 x 365 = 2920 kWh, so the first three brackets will apply to the customer. Specifically, on the bill, the customer's average daily consumption of 8 kWh will be divided as follows: * 4.93 kWh in the 1st bracket (1800/365); * 2.30 kWh in the 2nd bracket (840/365); * 0.77 kWh in the 3rd bracket (280/365). Where 1800 and 840 represent the size of the first two brackets and 280 is the portion of annual consumption that falls within the 3rd bracket.

Some unit prices have a differentiated value for annual consumption brackets. Each bracket is delimited by a minimum and a maximum level (e.g., 0-120 Smc; 121-480 Smc, etc.); a customer who consumes 400 Smc in a year will pay the price set for the first bracket for the first 120 Smc delivered; the price set for the second bracket for the remaining 280 Smc delivered.

Reconciliation method between delivered and redelivered electricity, applied in the event that the delivery and redelivery of electricity do not occur simultaneously.
