Chris,

As UK wind energy in some months are better than others, the conventional, quicker-ramping plants, such as CCGTs and OCGTs, have to reduce their outputs as wind energy surges and increase their outputs as wind energy ebbs many times per day, 24/7/365. Other conventional plants need to operate at lower loads because of wind energy displacing their energy

Such part-load-ramping operation by these conventional plants is inefficient (just as your car would be) and consumes more fuel/kWh and emits more CO2/kWh. Also, almost all these plants need to be kept in good operating condition and staffed, at a significant Owning+O&M cost, to provide energy when wind energy is nearly absent, as often happens in the UK and mainland Europe.

The extra fuel and CO2 nearly offset the fuel and CO2 wind energy was meant to reduce, as shown by the below studies of the Colorado, Texas, Ireland, and Dutch grids which show only a small reduction of CO2 reduction/kWh, much smaller than claimed by wind energy promotors.

These studies were written by engineers, diploma engineers, doctor engineers and professors, most of whom are retired and have decades of experience as energy systems analysts and energy consultants. Study the articles before preemptively dismissing.
