26
negative price-hours across 34 zones in August 2017
40.47
average day-ahead price, €/MWh, across covered zones
5
zones that cleared below zero at least once
August 2017 closed with 26 negative price-hours across the 34 European bidding zones with full coverage this month — 5 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 20.76 €/MWh); the priciest was IT-SICI (68.91 €/MWh) — a 48 €/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 (10), and the widest intra-month price range belonged to SI: from 5.06 to 199 €/MWh (193.94 €/MWh of spread — the raw material for every battery business case). The single deepest print of the month was -31.06 €/MWh in AT on 2017-08-20.
