Weekly Market Snapshot — Belgium, 2026-w34

Belgium's electricity market experienced a highly volatile week (10–17 August 2026), with day-ahead prices averaging €137.69/MWh against a backdrop of a pronounced inverse price profile — off-peak hours (€156.46/MWh) outpricing peak hours (€121.81/MWh) — driven by strong midday solar suppression and sharp evening demand ramps. Renewable generation averaged 53.6% of the mix for the week but deteriorated sharply toward week-end, collapsing to just 9.6% on 17 August as solar and wind output dropped, pushing fossil gas dependency to 90.4% and prices toward their weekly highs. Belgium remained a significant net importer throughout, drawing heavily from the Netherlands (avg. 2,085 MW) and France (avg. 1,129 MW) to bridge the gap between domestic generation and demand.

Weekly Market Snapshot — Germany-Luxembourg, 2026-w34

The DE-LU bidding zone experienced a highly stressed week (10–17 August 2026) with a mean day-ahead price of €132.1/MWh and an extreme intraday range spanning from near-zero (−€0.18/MWh) to €487.38/MWh, reflecting acute supply-demand imbalances driven by solar-heavy midday surpluses and sharp evening scarcity. Renewable penetration averaged 66.6% across the week but collapsed to just 30.7% on 17 August, exposing significant thermal dependency and residual-load volatility. DE-LU maintained a net exporting position across most interconnectors, though bilateral flows with NL and FR revealed notable scheduled-versus-physical deviations indicative of unplanned loop flows and cross-border congestion.

Weekly Market Snapshot — France, 2026-w34

France's electricity market recorded a highly elevated mean price of €136.5/MWh over the 7-day period (10–17 August 2026), with extreme intraday volatility driven by a pronounced solar generation mid-day trough and steep evening demand ramps. Nuclear dominance at 65.6% of total generation underpinned supply adequacy, while a steady week-on-week decline in renewable penetration — from 29.3% on 10 August to just 13.8% on 17 August — tightened residual load and supported persistently high prices. France maintained a net export position across all interconnected neighbours, confirming its role as a regional price-setter and power exporter despite the elevated market price environment.

Weekly Market Snapshot — Netherlands, 2026-w34

The NL bidding zone experienced an exceptionally volatile week (10–17 August 2026), with day-ahead prices averaging €132.64/MWh against a standard deviation of €72.14/MWh, reflecting a pronounced solar-driven mid-day price collapse juxtaposed with extreme evening scarcity spikes reaching €487.38/MWh. A sustained decline in renewable penetration from 37.6% on 10 August to just 9.6% by 17 August drove intensifying fossil thermal dispatch and tightening supply margins. The Netherlands remained a structural net exporter — particularly to Belgium at near-capacity utilisation — while a highly anomalous off-peak premium over peak prices signals a fundamental inversion of the conventional daily load curve driven by solar generation.
