average day-ahead price, €/MWh, across covered zones

zones that cleared below zero at least once

September 2019 closed with 28 negative price-hours across the 37 European bidding zones with full coverage this month — 4 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 NO1 (average 29.87 €/MWh); the priciest was GR (60.95 €/MWh) — a 31 €/MWh gap between two markets inside one coupled European system, which is the whole story of constrained interconnection in one number.

DE-LU logged the most negative hours (14), and the widest intra-month price range belonged to FI: from 6.56 to 199.98 €/MWh (193.42 €/MWh of spread — the raw material for every battery business case). The single deepest print of the month was -48.48 €/MWh in DE-LU on 2019-09-30.
