118
negative price-hours across 34 zones in October 2017
41.26
average day-ahead price, €/MWh, across covered zones
6
zones that cleared below zero at least once
October 2017 closed with 118 negative price-hours across the 34 European bidding zones with full coverage this month — 6 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 NO2 (average 27.14 €/MWh); the priciest was IT-SICI (74.28 €/MWh) — a 47 €/MWh gap between two markets inside one coupled European system, which is the whole story of constrained interconnection in one number.
AT logged the most negative hours (35), and the widest intra-month price range belonged to AT: from -76 to 120.23 €/MWh (196.23 €/MWh of spread — the raw material for every battery business case). The single deepest print of the month was -91.94 €/MWh in AT on 2017-10-29.
