A 2021 published study revealed that in the connected grid of in eleven countries surrounding the North and Baltic Sea areas, it was found that almost all periods tagged as Dunkelflaute events (with a length of more than 24 h) are in November, December, and January for these countries. On average, there are 50–100 h (2 to 4 days with no windpower nor sunpower) of such events happening in each of these three months per year. Through an interconnected EU-11 power system, the mean frequency of Dunkelflaute drops from 3–9% (I don't know what that means, does that come from: 2 days/90 days=2% - 4 days/90 days=4%) for the individual countries to approximately 3.5% for the combined region. [1] What is also relevant is the article on our EU-27 Synchronous_grid_of_Continental_Europe I need help. Sorry, no more time. Thy, SvenAERTS ( talk) 23:19, 5 September 2022 (UTC)
The unsourced text declares a low sun/wind event shall be longer than one day to be called Dunkelflaute. Next paragraph (sourced) states that most events are less than one day. Unless a source is provided for the first statement, it should be removed. Votpuske ( talk) 06:57, 22 November 2022 (UTC)
The text includes a calculation, 150h/8760h=1.5%. It is both arithmetically incorrect (should be 1.7%) and appears out of place: modern humans cannot survive without electricity for few days, no matter how small percentage of a year this interval constitutes. Unless a source tying the calculation to the subject of the article is provided, I think that the calculation shall be deleted. Votpuske ( talk) 07:02, 22 November 2022 (UTC)
