To be dependent on stock market power prices can bring some challenges. With the correct use of the dynamic tariffs, costs can be saved.

Coupling to the EPEX Spot Markt

While conventional electricity tariffs contain a fixed basic price and working price, dynamic electricity tariffs are linked to the “Epex Spot Markt”. This changes the prices for consumers every hour. In paragraph 3 No. 31d of the Energy Industry Act, dynamic electricity tariffs are defined as “a electricity delivery contract with a final consumer in which the price fluctuations on the spot markets, including the day-aha-outside and intraday markets, are reflected in intervals that at least correspond to the accounting intervals of the respective market”.

Profit with high consumption

By coupling to the electricity exchange, households with high power consumption can benefit. However, electric cars, battery storage or heat pump should be available in order to be able to shift part of the load in times of low prices. Without such a relocation option, “the risk of rising prices outweighs the advantages far,” explains the consumer center.

According to a model calculation of the ADAC, the electricity costs in a household with four people and an energy requirement of 4,000 kWh could be reduced by more than 350 euros per year. The costs can be contained further, you have a photovoltaic system: “If you have a PV system, you can supplement the independence obtained with a dynamic electricity tariff and thus save as much as it is when you remain the remaining network cover. Because the e-car battery or the home memory can be exhausted at night-if the wind blows particularly strongly at night”, emphasized Merlin, “emphasized Lauenburg, head of Germany of Tibber, in conversation with the ADAC.

Prerequisite: smart meter

An intelligent measuring system, a smart meter, is required to bill the hourly price changes. This measures consumption once a day and transmits this data to the measuring point operator. Only since January 1, 2025, households have been able to charge installation. Households with heat pump or electric charging station are 50 euros per year for the measuring system.
