How are savings, as well as old and new bills, calculated in the simulation?
Savings=Sum of old bills for all consumers−(Sum of new bills for all consumers−Feed-in tariff)
In principle, all consumers and generators can already exist (and thus be counted toward old bills) or be newly planned (of course, this does not apply to fossil heating systems).
All consumers can be assigned their own energy prices, which are then used to calculate the bills.
Consumers:
Old heating system (oil/gas, pellets, district heating)
Heat pump
Wallbox
Household electricity
Generators:
PV system (including feed-in tariff)
Note: Currently, wallbox, heat pump, and PV systems cannot yet be included as existing systems in the before/after simulation. This function will be available soon.
