The generation mix (trailing 30 days)
FR runs on a nuclear backbone (68.2% 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 500.8 hours so far this year (live counters on the tracker), inside a year-to-date range of -496.86 to 338.86 €/MWh. Our serving model (volt-6sa) currently runs 10.6% less error than the naive baseline (live, 19 scored days) — verified daily on the public scorecard.
Method. Mix shares from realized generation (ENTSO-E A75, trailing 30 days); price stats from hourly means of published day-ahead auction results (2026 YTD). Every figure recomputes continuously — this page is a query, not an essay with a shelf life. Cite as "Voltcast Research, voltcast.com".
