The generation mix (trailing 30 days)

Wind 0% Solar 22.9% Hydro 26.3% Nuclear 45.4% Fossil 3.5%

SI runs on a nuclear backbone (45.4% of recent generation). Baseload is cheap and steady, so the price action lives in the margins: demand swings (this market is highly temperature-sensitive), the availability of the reactor fleet, and how much wind/solar shows up. Outage seasons — planned or otherwise — are the risk events worth watching.

The zone has cleared negative 212 hours so far this year (live counters on the tracker), inside a year-to-date range of -473.75 to 1041.47 €/MWh. Our serving model (volt-3) currently runs 19.6% less error than the naive baseline (backtest, 28 scored days) — verified daily on the public scorecard.
