Turbine blades in Finland iced over

In Finland, wind turbine blades iced up, causing electricity generation to drop from 9,433 MW to approximately 430 MW—less than 5% of nominal capacity. According to industry experts, the cause was severe cold from the east, dubbed 'Russian frost.' These weather conditions, they say, were not accounted for in planning the country's green transition and significantly limited wind farm operations.

Context

Finland is actively developing wind power as part of its goals to switch to renewable energy sources.
