I’m not really that qualified either but fwiw the quotes in the article from the NREL paper on grid stability in low inertia settings ignore that the NREL also mentions that ERCOT has managed to deal with higher renewables penetration successfully using load response, and that we likely won’t see this as an issue in the US in the next decade. Rest assured that ancillary services markets absolutely incentivize frequency regulation (if not inertia directly), and in fact a significant portion of energy storage returns so far has been from providing frequency control (and getting paid for it). Overall I also found this post to be fear-mongering.
