Italy's zero-price hours jump 340% in H1 2026

Italy's wholesale market recorded 88 zero-price hours in the first half of 2026, up from 20 in the same period of 2025, per pv magazine. The fourfold rise points to accelerating solar-driven oversupply during daylight windows in the Italian zone.

The pattern fits a broader European dynamic flagged by Reuters on 31 July: summer power prices across the continent are reaching levels that historically matched winter peaks. That divergence means zero-price floors at midday and high-price ceilings during heat-driven evening demand. It compresses capture prices for solar assets and widens the spread for flexible generation and storage.

For Italian market participants, the 88-hour figure is the clearest H1 data point yet on how structural oversupply is reshaping the price duration curve in the zone.
