750
negative price-hours across 43 zones in March 2025
85.19
average day-ahead price, €/MWh, across covered zones
26
zones that cleared below zero at least once
March 2025 closed with 750 negative price-hours across the 43 European bidding zones with full coverage this month — 26 of them cleared below zero at least once. Negative prices are no longer an anomaly; they are a structural feature of a grid where solar and wind routinely outrun demand.
The cheapest market of the month was NO4 (average 5.12 €/MWh); the priciest was IE-SEM (131.76 €/MWh) — a 127 €/MWh gap between two markets inside one coupled European system, which is the whole story of constrained interconnection in one number.
SE2 logged the most negative hours (189), and the widest intra-month price range belonged to EE: from -11.53 to 773 €/MWh (784.53 €/MWh of spread — the raw material for every battery business case). The single deepest print of the month was -235.61 €/MWh in DE-LU on 2025-03-22.
