MTU stands for Market Time Unit – the smallest time interval for electricity prices on the exchange. In Germany, the MTU has been 15 minutes since 2021.
What Does This Mean?
- 96 prices per day: A new price every 15 minutes
- More flexibility: Finer control of consumption and storage
- Better arbitrage: More opportunities for price differences
Why Was MTU Shortened?
Previously, MTU in Germany was 60 minutes (24 prices/day). The switch to 15 minutes was made to:
- Better integrate renewable energies (rapid fluctuations)
- Increase flexibility for storage and controllable loads
- Advance European harmonization
