The total capacity as of May 2020: 6.19
The figure is reported by ens.dk
2019 average capacity factor:
CF = 8273 / 365 / 24 / 6.10 x 100 = 15%
The Battery Solution
Many people, even on government level, suggest that we can rely on wind
for 100% continuous of our electricity by installing batteries.
This idea implies that we no longer need power from conventional power stations.
We would first need to have more windmills, so that practical CF covers
max consumption plus energy loss.
Next we need batteries for when to sustain balance, inertia and times when the wind is weak.
Let us optimistically assume we will never have wind weak period of longer than 7 days
and optimistically assume the a 7 day period of optimal wind will follow to recharge plus supply consumption.
Battery capacity would the need to be for 5 GW max consumption.
7 days (168hours) * 5 GW = 840 GWh
or about 17 million 50 kWh electric car batteries to be replaced
every 10 years or so.
The above 840 GWh estimation is just to give a pointer to the size of grid scale battery capacity needed,
and it is extremely optimistic.
All these resources, seascape and landscape use could be avoided by using existing conventional power plants
and forget the elite's expensive dream that sounds nature friendly, but is in fact:
- increasing the rates
- increasing the taxes
- increasing the nature destruction
- increasing the mineral depletion
- increasing the international dependency
- increasing the pollution
