Simplified peak billing
Last modified:
The simplified peak billing model is similar to peak billing but uses data from external weather services rather than data measured on-site. It is based on the German "vereinfachte Spitzabrechnung” but can be applied to any system that meets the prerequisites. VCOM searches the last 3 months of data for a valid reference period.
Prerequisites
Irradiation data from an external weather provider.
Relative active power setpoint value of any source.
The derated power must be lower than the expected power.
The measured power must be lower than the expected power.
Note
As data from external weather providers is usually only available the night after the specific event, the simplified peak billing can only be calculated on the next day.
