Interpretation of the electricity bill and choice of parameters that allow lower monthly household expenditure on electricity. Far from going into technicalities of specialists in the power sector, should clarify the electric bill, so that any ordinary person can interpret and engage optimally.
If you take a receipt type, different concepts that we determine the total expenditure contracted power, energy consumed; Tax on electricity; Measurement equipment rental; VAT.
Electric power contract:
The concept called “contracted capacity” is determined by three parameters: the contracted power itself, the days billed and the power term.
* The contracted power: At present there are different degrees of electrification, the most common, basic level of electrification, with a limit of 5,750 watts. More than enough power for a housing type, with the usual appliances and some air conditioning equipment (eg living room and a bedroom).
* Days billed: Each receipt shows the number of days billed, which may vary between 30 and 60 days, depending on whether the bill takes a month or two.
* Power term: Is a fixed parameter in euro / kW day.
Relationship between power and intensity
The power to contract depends on the limiting current that can flow through the facility, “a simile easy to understand, would equate the electric current passes through the facility, with the water flow that could pass for the water supply.
When hiring, there are different levels of power supported by the company, depending on the devices that limit the input current in the system. When we say we hired 5,750 watts, we are actually limiting the installation to a current of 25 amps.
Intensity equivalent power
Equivalence relationship with current contracted capacity contracted, indicating the limitations of the market: 2,230 watts 10 amps, 3450 watts 15 amps, 4600 watts 20 amps, 5750 watts 25 amps, 7360 watts 32 amps, 9200 watts 40 amps.
Election of the power to hire
This first concept reflected in the receipt shows that the higher the contracted power, the greater the expense. It is therefore important to determine the power that we need, thus, cling to the power required. Although it is customary to hire 5,750 watts (25 amps), with 4,600 watts (20 amps) would be more than sufficient in many cases, which would save.
The formula for determining the term “contract power” is: Contracted power = Power x days x Tp.
* Power: power that we’re hiring.
* Days: are the days of billing.
* Tp: the term of power.
Energy consumed
The concept “Energy efficiency” is determined by two parameters: the power consumed and the energy term.
* The power consumed. The number of watts that we consumed. The invoice appears expressed in kWh, which is equal to 1,000 watts per hour. An iron with a power of 500 watts, if used for two hours, consume 1,000 watts, equivalent to 1 kWh.
* Energy term. Is a fixed parameter expressed in euros Kw h. This value may vary according to the company, because if there free market, there are differences in rates.
Choice of power company
The second concept reflected in the receipt shows that the higher the power consumed and the greater the energy term that we offer the company, the greater the expense. It is therefore important to make a comparison of the different offerings of the utilities.
The formula for determining the concept of “energy efficiency” is: Energy = Power x Te consumed
* Power: power consumption.
* Te is the energy term.
Tax on electricity
It is a percentage applied to the sum of the two previous concepts.
Measuring Equipment Rental
Fixed fee per day rental counter
It is possible to buy the counter at the time of hiring, which would no longer rent. In this case, if a fault occurs on the counter, we can not claim from the airline.
VAT: Value added tax, which applies to the sum of the above concepts.
The contracted power and electricity rates are the parameters that we choose to get to optimal recruitment and thereby reduce the amount of the invoice.
