France expands renewable curtailment mechanism amid negative prices, lowers threshold to 1 MW
France will expand its renewable curtailment mechanism to more solar and wind installations, lowering the capacity threshold from 10 MW to 1 MW in two stages from December 2026. The rules target periods of negative electricity prices, with EDF preparing affected operators for remote shutdowns while maintaining existing compensation arrangements.

Three-year testing assesses wind flow dynamics in solar plants
A French research team analyzed nearly three years of wind and turbulence measurements over a 140-hectare photovoltaic park in southwestern France, comparing it with a nearby pine forest to understand airflow behavior above PV canopies. They found that wind direction relative to panel rows strongly controls turbulence and drag, and they developed a generalized wind-profile parameterization to better represent PV parks in land–atmosphere and weather models.
