Fixed-price tariffs are usually more expensive in the long term,
because the supplier adds a margin to the purchase price and intelligent electricity consumption is not rewarded.
Dynamic electricity tariffs pass through the exchange electricity price and therefore create incentives to
consume more at cheaper times.
So this not only means that a dynamic electricity tariff is cheaper in the long term, but also that with smart
consumption (through a heat pump, solar, wallbox), significant additional costs can be saved.
