15 snips
Oct 3, 2025 Jerome Le Page is the Chair of the Electricity Committee at Energy Traders Europe, while Jean-Paul Harreman is the Director at Montel Analytics. They discuss the recent rollout of 15-minute day-ahead auctions and its impact on market volatility. Le Page shares insights on trader sentiment and legislative contexts, while Harreman explores zigzag pricing patterns linked to cross-border capacity calculations. Both emphasize the potential for this new granularity to attract flexibility providers and enhance market integration of renewables.

Episode notes
Salt-Tooth Pattern From Hourly Capacity
- A 'salt tooth' pattern seen before reappeared: some quarter-hours within the hour consistently differ due to flow-based hourly capacity calculations.
- Hourly cross-border capacity rules remain a frontier to harmonize for true quarter-hour consistency.
Test Auctions During Stress Events
- Monitor weekend and high-wind days to test how auctions handle more complex bids and volatility.
- Prepare for more bids and different dynamics as renewables and shaping needs increase.
Mobilize Smaller Flexibility Players
- Encourage smaller flexibility providers to participate by exposing day-ahead price signals and enabling aggregators.
- Use price signals to mobilize demand-side response alongside production-side flexibility.
