Wind power is a total joke. It is just an excuse to rape the taxpayer and rate payer for the benefit of landowners, windmill manufacturers and politicians.
Peak is one thing. The complete duty cycle is quite another. I’ll bet that overall the average number of MWe generated is less than 20% of nameplate capacity.
Plus, peak production is when the wind conditions are optimal. How often do we suppose those peaks line up with demand? In fossil and nuke plants you can ramp up production for predictable peak demand times. Plants can be in ‘spinning reserve’ ready to go online when dispatched to accommodate demand. Gas turbine plants can be quickly started when there are frequency drops due to trips or unexpected outages.
The point is the utility can throw a switch and bring up a power plant on line with a reasonable expectation that it will respond. You can’t just whistle up a few thousand MWe of wind.
