Output peaks during low output periods are only considered if the monthly low output
peak reaches a level above the given annual peak power output at peak load times. The
monthly differences of these values are sorted according to size and an average value is
calculated. The resulting difference is only partly used in the calculation, the factor is
entered in the Load Price dialog. The number of months used for producing a figure for
the light load peak is also entered in the Load Price dialog. The sum of the heavy load
maximum and the allowed for light load share gives a figure for the calculated power.
Set Load Price:
The electricity payment is made up of two parts: a set price and a price dependent on
consumption. The set load price must always be paid separately from the price for grid
power actually used.
Hourly Peaks in the Defined Load Plus:
(only for Standard Calculation and Heavy/Light Load Maximums)
Depending on the grid utility company, monthly power outputs are measured in ¼ or ½
hour averages. The highest output during the year is multiplied with the given specific
load price, in order to give a figure for the annual load price that will have to be paid. In
the programme the highest monthly output figure is the highest occurring average
hourly output in each month (to account for the time stages). This leads to lower output
peaks because the ¼ hour variations are levelled out. In order to correct this the
highest monthly outputs for calculating the highest annual output are multiplied by the
¼ hour peaks in the defined loads plus. Depending on the type of appliance, the size of
the area supplied, and any measured loads to hand, a percentage figure between 0%
and 50% must be entered here. For typical housing estates with an annual consumption
of more than 100,000 kWh, an annual consumption of 5-10% can be used for the
calculation.
Minimum Power Output:
(only for Standard Calculation and Heavy/Light Load Maximums)
This measure is only used in the calculation if the maximum output is less than this value.
Wholesale Provision:
(only for Standard Calculation and Heavy/Light Load Maximums)
Instead of a set load price, a price for wholesale provision can be requested. This is paid if
the hours of full use (HFU) do not reach the set threshold value. The wholesale provision
price (WPP) is calculated as follows:
WPP = price [€/kW] * max. power output
* (1 HFU/hours of minimum use)
Max. power output: the maximum power output calculated by the programme, or possibly
the minimum output.
HFU:
Hours of full use = total annual kWh output/maximum output
