Electricity Generation #DK

Generation of wind electricity is very intermittent due to weather fluctuations. It is obvious to everyone that wind speed is very variable, but what is less obvious is the fact that these variations are coherent over whole countries such that the total country-wide wind power output can fall to very low values.

The largest component of generation is wind power at 56%. Data on fuel mix demand variations.

The lows in wind power generation are generally compensated by increased fossil fuel generation. Some countries use imports and exports to compensation for wind lows and highs.

Denmark is the largest European country where wind+solar energy dominants the electricity generation. To compensate for the large wind fluctuations it has a large dependence on imports which are 17% net over the year but often much greater for short periods
