12.4 Outgoing Cost of Energy from Utility Grid
Here you are given a detailed list of variables for energy use under the headings: Kilowatt-
Hours, Load and Discounts/Supplements, and the resulting costs (payments to the
electricity utility). The values are given for two scenarios: With PV System and Without PV
System.
Without PV System - the cost of electricity used is determined by the energy consumption
of the electrical appliances.
With PV System – the cost of electricity used is determined by the amount of energy
drawn from the grid.
Depending on the supply concept (see Tariffs), the energy used by the electrical
appliances plus the energy used by the PV system itself is provided exclusively by the grid
(Full Supply), or, with Net metering, the amount of energy generated by the PV system
must be deducted from this amount.
The name of the tariff on which the calculation is based is shown in the field at the top of
the window. The tariff is defined under the menu Conditions > Tariffs.
The results of the tariff calculation are given in a detailed table, divided into three areas:
Work, Power and Discounts/Supplements. A summary with the final result Total Payment
is given in a field at the bottom of the window.
Work:
Specific Costs: Average specific costs in the given period.
Energy from Grid: The number of kilowatt-hours of energy drawn from the grid in the given
period.
Costs: costs before the deduction of discounts and the addition of supplements.
Payments: costs after the deduction of discounts and addition of supplements.
Power:
Set Load Price: the set demand price as entered or the estimated price for wholesale
provision of power to the utility.
Heavy Load Peak: for heavy/light load capacity measurement, the heavy load peak is
given here.
Billing Load (Output Value): The output that is included in the billing calculation is given
here, or, if a 96 hour tariff is in use, the output value is given.
Specific Load Price: Average specific load price in the given time period.
Consumption Dependent Load Price: billing load * specific load price.
Total Power Payment: represents the sum of the set and consumption dependent power
prices after deduction of discounts and addition of supplements.
