Germany and Luxembourg Wind, Solar and Electricity Prices, 2026

In Germany and Luxembourg, across 398 days from 2025-08-18 (18 August 2025) to 2026-09-19 (19 September 2026), the average day-ahead price on the quarter of days with the highest wind and solar share was EUR 66.96/MWh, against EUR 123.96/MWh on the quarter with the lowest share (EUR 57.00/MWh lower). The correlation between the two is -0.61, a strong tendency for days with more wind and solar to have lower average prices. Prices are day-ahead, in EUR per MWh as published, and are not converted. Correlation is not causation.

What the Correlation Says

The Pearson correlation between the daily wind and solar share and the daily mean day-ahead price in Germany and Luxembourg is -0.61 over 398 days: a strong tendency for days with more wind and solar to have lower average prices. Among the 39 zones on the main page, it ranks 6 from the strongest negative link.

Correlation is not causation. Season, weather, demand, gas prices and imports all move at the same time as wind and solar output, so this figure describes how the numbers moved together in this window, not what wind and solar caused. It uses daily averages only.
