He speaks the truth. The frequency of the system can deviate slightly from 60Hz to take care of small differences between power produced and consumed. Intertie connections can also be used to “socialize” the imbalance.
“Feathering” is limited in some cases as this technology has not been fully spread to all wind generation. Bottom line is wind and solar are poor forms of power relative to hydro and nat gas. Once a grid has too much wind and/or solar reliability goes. It is very much a case of diminishing returns as wind is added to a grid.
Something doesn’t line up here. Wind turbines don’t have to spin at constant rate to match the 60 hz line, at least not the modern ones. They have power freq converters to match the output of the generator to the line freq. That’s pretty fundamental.
If you can cite for me the electrical specs for a modern wind generator, that say it has to spin at exactly the right speed to match the 60 hz line freq, I’ll stand corrected. But that’s not my understanding.
BTW, I think large scale wind plants are foolish as hell. Small scale wind generation works fine. Say, household or farm size. Large scale is a boondoggle.

Don’t forget ‘smart’ meters. They’ll simply shut off crap in your house when the wind stops blowing, or the sun stops shining - or they’ll just black you out if they need to. We will be living a new lifestyle with those monsters.
