zones that cleared below zero at least once

December 2019 closed with 147 negative price-hours across the 38 European bidding zones with full coverage this month — 10 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 DE-LU (average 31.94 €/MWh); the priciest was GR (59.7 €/MWh) — a 28 €/MWh gap between two markets inside one coupled European system, which is the whole story of constrained interconnection in one number.

IE-SEM logged the most negative hours (46), and the widest intra-month price range belonged to IE-SEM: from -11.86 to 205.25 €/MWh (217.11 €/MWh of spread — the raw material for every battery business case). The single deepest print of the month was -50.43 €/MWh in DE-LU on 2019-12-08.
