Dynamic Electricity Tariffs: Fixed Prices Often Cheaper According to Verivox
The Challenges of Dynamic Tariffs
Dynamic electricity tariffs have gained popularity as a method for households to potentially save on energy costs by adjusting their electricity consumption according to changing market prices. However, a recent analysis by the comparison portal Verivox suggests that these tariffs may not always be the best option. Households with fixed-price contracts appear to fare better, particularly those not optimizing their usage patterns.
Key Findings from the Verivox Analysis
In the first half of 2026, households using fixed-price contracts were found to spend less than those relying on dynamic tariffs. Specifically, a three-person household with a typical annual consumption of 4,000 kilowatt-hours (kWh) could save money by opting for a fixed rate. Dynamic tariffs, which adjust their rates according to market prices, only yield savings if consumers actively shift their usage to low-cost times.
For example, those who successfully managed their electricity use—running appliances like washing machines and dishwashers during cheaper hours—spent roughly €604. However, without this optimized behavior, costs escalated to €645.
Comparisons with Different Tariff Models
When compared to households using the basic supply tariffs—often subscribed by those who have not switched providers—dynamic tariffs initially seem attractive. The latter group recorded significantly higher bills of around €787 during the same timeframe, highlighting the potential savings that might emerge from utilizing dynamic pricing.
Conversely, in cases where an electric vehicle (EV) is involved, dynamic tariffs can show more substantial benefits. An EV household, consuming about 6,000 kWh, would typically see costs of €821 on a dynamic tariff. This is a considerable drop compared to the €1,189 incurred under basic supply conditions, showcasing how nighttime charging during low market prices can be economically advantageous.
The Role of Customer Bonuses
Households signing contracts under the lowest fixed-price offerings, including welcome bonuses, reported even lower costs of approximately €588. This not only illustrates a more favorable outcome for users of fixed contracts but emphasizes the appeal of more predictable expenditure in the often-fluctuating electricity market.
Dynamic tariffs could potentially offer even more savings with the introduction of time-variable network fees, enabling consumers to benefit from lower charges during off-peak hours. However, many network operators have yet to implement these structures fully.
Requirements for Use of Dynamic Tariffs
To engage effectively with dynamic tariffs, households must invest in smart meters equipped with smart meter gateways. The operating costs associated with these setups generally range between €30 and €110 annually, based on the household’s electricity consumption, further contributing to the overall expenditure for dynamic tariff users.
Methodology for Analysis
The basis for Verivox’s analysis involves statistical models reflecting the electricity consumption patterns of typical households throughout the day. The data used for market prices was gathered from the Day-Ahead auctions of the European Epex Spot exchange, which provides insights into how much electricity will cost on the following day.
Dynamic tariffs considered in this analysis included additional costs of 0.731 cents/kWh and a monthly base fee of €5.03, correlating to the lowest rates available at the time. The optimization scenario reflected a practice where 15% of daily consumption was shifted from high-cost evening hours to the three cheapest hours available.
Conclusion
While dynamic tariffs may present a future-forward approach to electricity pricing, current data indicates that fixed-price contracts often provide more financial security and lower overall costs for the average household. Those considering dynamic tariffs must weigh the potential benefits against their capability to adapt their usage effectively. As electricity markets continue to evolve, so too will the strategies households use to manage their energy expenses.
