The “Mäi Stroum dynamic” electricity price follows the evolution of the EPEX SPOT (European Power Exchange) Day‑Ahead wholesale market, the European trading platform where electricity is bought and sold. The Day‑Ahead prices can vary significantly from one quarter‑hour to the next and from one day to another.
Here are two examples that illustrate the extent of these fluctuations. Please note: These two days intentionally show very extreme price situations. They are real cases, but provided purely for illustrative purposes and do not reflect either the general price trend in 2025 or future prices.
Example 1: a day with very high prices
Monday, 20 January 2025
- During the night, when electricity consumption is generally low, prices were still around €116/MWh.
- By the end of the day, at the consumption peak (around 5 p.m.), prices rose sharply to €583.4/MWh.
In winter, especially in the early evening, demand is very high, which leads to rising prices: people arrive home, turn up electric heating, charge their cars, etc.
Example 2: a day with mostly negative prices
Saturday, 4 October 2025
- At 3:15 p.m., the price dropped to –€5/MWh.
- The highest price of the day was reached at 7:30 p.m. and even then, it was only €4/MWh.
Prices can turn negative when electricity production is very high while demand is low (for example on weekends).
In these situations, producers literally pay consumers to take the excess electricity off their hands.
