Weekly Market Snapshot — Belgium, 2026-w31

Belgium's electricity market over 20–27 July 2026 was characterised by exceptionally high price volatility, with a weekly mean of €107.72/MWh masking a swing from -€11.35/MWh to €212.00/MWh and a standard deviation of €62.29/MWh. A pronounced solar-driven midday price collapse contrasted sharply with steep evening ramp prices, while the zone remained a significant net importer, drawing heavily from France (avg. 2,421 MW) and the Netherlands (avg. 1,139 MW). Renewable penetration averaged 58.4% across the week but fluctuated dramatically day-to-day, directly driving the residual load and thermal dispatch requirements.

Weekly Market Snapshot — Germany-Luxembourg, 2026-w31

The DE-LU bidding zone recorded a highly volatile week (20–27 July 2026), with day-ahead prices averaging €104.06/MWh against a standard deviation of €65.17/MWh — reflecting extreme intraday swings driven by solar saturation midday and elevated evening demand. Renewable generation dominated the fuel mix at 69.7%, with solar alone contributing 32.1% of total output, yet 12 negative-price hours signal persistent midday oversupply that thermal and storage dispatch could not fully absorb. The zone maintained a net export position across most interconnectors, with France emerging as the dominant import counterparty and NL, AT, and PL absorbing the bulk of DE-LU exports.

Weekly Market Snapshot — France, 2026-w31

The French electricity market exhibited extreme price volatility over the 7-day period (20–27 July 2026), with day-ahead prices ranging from -€11.32/MWh to €204.95/MWh against a weekly mean of €90.98/MWh and a standard deviation of €70.01/MWh — reflecting the deep solar-driven midday price collapse and steep evening ramp characteristic of high-renewable summer dispatch. Nuclear baseload dominated generation at 68.9% of the mix, underpinning France's strong net export position of approximately 1.4 TWh across all interconnectors over the period. A notable decline in renewable share from 33.1% on 20 July to just 17.0% by 27 July signals tightening supply conditions entering the following week.

Weekly Market Snapshot — Netherlands, 2026-w31

The NL bidding zone experienced a highly volatile week (20–27 July 2026), with day-ahead prices averaging €105.2/MWh but ranging from -€13.24 to €213.38/MWh, reflecting extreme solar-driven midday suppression and steep evening ramp events. Renewable penetration fluctuated sharply between 19.8% and 56.7% across individual days, creating significant residual load swings that kept the thermal fleet — dominated by gas (30.6%) and hard coal (26.1%) — under substantial dispatch pressure. NL maintained a net import position from DE-LU while simultaneously exporting heavily to BE, acting as a transit hub with near-capacity utilisation on the NL→BE interconnector.
