    energy_price: float = 0.0697,
    feed_in_tariff: float = 0.0608,
    taxes: float = 0.0149,
    time_delta_seconds: int = 900,
) -> Dict

Performs the calculation of the yearly electricity bill.

Parameters:

Name	Type	Description	Default
`taxes`	`float`	See https://www.bdew.de/service/daten-und-grafiken/bdew-strompreisanalyse/	`0.0149`
`grid_tariff`	`GridTariff`	A `GridTariff` which defines the costs of using the electricity grid. See `grid_tariffs.py` for different tariffs.	required
`list_of_grid_power_utilization`	`Iterable[float]`	The power profile in kW that defines how the grid was used.	required
`energy_price`	`float`	Price per kWh energy. The default value is set by using the arithmetic mean of the 1st half of 2024 of the day ahead stock market prices (https://energy-charts.info/).	`0.0697`
`feed_in_tariff`	`float`	Defines how many € is paid per kwh energy fed into the grid. The default value is based on the EEG 2024 and holds for PV systems between 100 and 1000 kWp. For more information see: https://www.bundesnetzagentur.de/DE/Fachthemen/ElektrizitaetundGas/ErneuerbareEnergien/EEG_Foerderung/start.html	`0.0608`
`time_delta_seconds`	`int`	Defines the delta in seconds between two power values in the `list_of_grid_power_utilization`.	`900`

Returns: A dict representing the electricity bill.

nrgise.economics.behind_the_meter.electricity_bill_calculator.main.calculate_grid_charges ¶

calculate_grid_charges(
    grid_tariff: GridTariff,
    time_delta_seconds: int,
    list_of_grid_power_utilization: Iterable[float],
) -> GridCharges

Calculates the grid charges based on the so-called usage hours ("Benutzungssstunden").

nrgise.economics.behind_the_meter.electricity_bill_calculator.main.calculate_grid_power_cost_for_one_year ¶

calculate_grid_power_cost_for_one_year(
    list_of_grid_power_utilization: Iterable[float],
    power_price: float,
) -> float

Calculates the part of the grid charges caused by the power utilization of the grid. Note that the price is calculated on a yearly basis. Please see https://www.energie-lexikon.info/registrierende_leistungsmessung.html for more information on how the power prices are determined.

nrgise.economics.behind_the_meter.electricity_bill_calculator.main.calculate_usage_hours ¶

calculate_usage_hours(
    list_of_grid_power_utilization: Iterable[float],
    time_delta_seconds: int,
) -> float

The calculation of the grid charges ("Netzentgelte") depends on the so-called usage hours ("Benutzungsstunden" or "Jahresbenutzungsdauer"). Note that the usage hours are calculated per year. The benutzungsstunden are calculated by: "benutzungsstunden" = "sum of energy of one year in kWh" / "max power of this year in kW"
