The generation mix (trailing 30 days)

Wind 8.3% Solar 21.1% Hydro 31.2% Nuclear 9% Fossil 28.4%

RO is a genuinely mixed system with hydro as the largest recent source (31.2%). No single technology sets the price every hour, so the merit order shifts across the day — renewables' output decides which plant is marginal, and that plant's fuel decides the price. Expect weather-driven volatility layered over a fuel-cost floor.

The zone has cleared negative 167 hours so far this year (live counters on the tracker), inside a year-to-date range of -97.55 to 954.59 €/MWh. Our serving model (volt-4) currently runs 18.6% less error than the naive baseline (backtest, 29 scored days) — verified daily on the public scorecard.
