An interesting article from Pat Swords:
There is now in 2019 approximately 3,700 MW of wind energy installed in the Republic of Ireland with an additional 1,300 MW installed in N. Ireland. As can be seen from the Figure 1 below, for extended periods there is little or no wind power output, and then when a low pressure system moves in, the wind turbines all rush on to the grid at the same time.

This is also clearly demonstrated in Figure 2 overleaf showing electricity demand and wind power output from early September 2019 to early October 2019. For large periods of the time, there was simply little or no wind energy, which when it was available generally rushed on to the…
