From October 1, 2025, the European electricity market will undergo a radical change. The price of electricity will no longer be calculated per hour, but per 15 minutes. This means 96 price intervals per day. These so-called quarter-hourly energy prices will provide more dynamism, more transparency, and above all: new opportunities to reduce your energy bill.
What are quarter-hourly energy prices?
Until now, electricity was purchased in one-hour blocks. Suppliers, for example, bought 100 units of electricity for an hour, but in reality, demand was often much more erratic: 120 units in the first quarter, 80 in the last.
With the introduction of quarter-hourly electricity prices, this will be a thing of the past. The market adjusts every 15 minutes to actual supply and demand. This leads to:
- Lower imbalance costs
- More efficient grid usage
- More accurate billing for consumers and businesses
Why switch to quarter-hourly prices?
The growth of solar and wind energy makes our electricity system less predictable. Sun and wind fluctuate rapidly, making the old hourly system inadequate.
With dynamic energy prices per quarter-hour, you can take advantage of times when electricity is cheap, for example, when there is a lot of sun or wind. Smart users can save up to 15% on their energy bill.
Which suppliers offer dynamic energy prices?
More and more energy suppliers are offering contracts with quarter-hourly prices or dynamic tariffs. Pioneers give customers the chance to automatically control their consumption through smart systems.
Other suppliers will temporarily stick to hourly prices. Therefore, it is important to check which contract you have and whether you can already benefit from quarter-hourly prices.
What does this mean for consumers and businesses?
For households:
- You pay exactly for the moment you consume electricity.
- With smart batteries, charging stations, or heat pumps, you can automatically charge during cheap quarter-hours.
- You avoid peak hours with high prices.
For businesses:
- Dynamic energy management structurally lowers costs.
- Energy storage (such as batteries) and solar farms become more valuable.
- You gain control over peak load and grid costs.
