Wind turbines in Finland set an all-time high production record on Sunday evening, according to the national grid operator Fingrid.
At around 7pm, the turbines generated electricity at an average power of 6,448 megawatts (MW), which is equivalent to the output of four Olkiluoto 3 nuclear reactors.
At that time, 12,265 MW of electricity were generated per hour, meaning that half of all electricity produced in Finland came from wind power.
"In the evening, almost as much electricity was exported from Finland to Estonia and Sweden as the transmission connections allowed," said Arto Pahkin, manager of the Main Grid Control Centre at Fingrid.
Due to the electricity surplus, hydroelectric power production was minimised, and Olkiluoto 3 also decreased its output.
Among Finland's nuclear power plants, Olkiluoto 3 participates in the electricity regulation market, allowing its production to be temporarily adjusted as needed.
Thanks to strong and favourable wind gusts, the price of electricity on the exchange dropped to a low level over the weekend.
Despite reaching an all-time high production record, wind turbines in Finland were still operating below their maximum capacity of 7,898 megawatts.
